Building operational weather and climate services for sustainable development in the global South

Weather and Climate Services (WCS) involve the production, translation, delivery, and use of science-based information for decision-making. The production of WCS makes use of long-term climate projections, climate and weather predictions from daily to decadal timescales, historical hydrometeorological data, and sectoral models to predict risks of climate impacts to society. These services are developed and delivered in support of (i) climate-sensitive sectors such as agriculture, management of water resource, health, energy and disaster risk reduction, and (ii) developing countries where the vulnerability to climate change and extreme weather events is high. This session, interdisciplinary in nature, aims at showcasing tools, products and methodologies that could be standardized for an operational and innovative system of WCS delivery in developing countries. The session invites contributions that include a) improvements of models and data analysis for WCS; b) engagement with end-users of WCS; c) assessment of the value of WCS’s outcomes and the corresponding impacts on societies and the environment; d) strategies for broad communication of WCS information to multiple audiences; and e) WCS partnerships between multiple stakeholders such as end-users, NGOs, government ministries, policymakers, and the private sector. The session particularly encourages lessons learned and results from different case studies coming from the global South.

Between 1970 and 2019, 79% of disasters worldwide involved weather, water, and climate-related hazards. These disasters accounted for 56% of deaths and 75% of economic losses from disasters associated with natural hazards reported during that period. As climate change continues to threaten human lives, ecosystems and economies, risk information and early warning systems (EWS) are increasingly seen as key for reducing these impacts. The majority of countries, including 88% of least developed countries and small island states, that submitted their Nationally Determined Contributions (NDCs) to UNFCCC have identified EWS as a “top priority”.

This latest multi-agency report, coordinated by WMO, highlights progress made in EWS capacity – and identifies where and how governments can invest in effective EWS to strengthen countries’ resilience to multiple weather, water and climate-related hazards. Being prepared and able to react at the right time, in the right place, can save many lives and protect the livelihoods of communities everywhere.

Despite recent and mostly global efforts to promote climate services in developing countries, Africa still faces significant limitations in its institutional infrastructure and capacity to develop, access, and use decision-relevant climate data and information products at multiple levels of governance. The Enhancing National Climate Services (ENACTS) initiative, led by Columbia University’s International Research Institute for Climate and Society, strives to overcome these challenges by targeting the way climate-sensitive decisions are made at the local, regional, and national levels. The ENACTS approach is executed by working directly with the National Meteorological and Hydrological Services (NMHS) to build capacity for improving the availability, access, and use of quality climate data and information products at relevant spatial and temporal scales. The ENACTS approach has shown to be an effective means to transform decision-making surrounding vulnerabilities and risks at both national and local scales in over a dozen countries at the national level as well as at regional level East and West Africa. In the ENACTS approach, challenges to the availability of climate data are alleviated by combining quality-controlled station observations with global proxies to generate spatially and temporally complete climate datasets. Access to climate information is enhanced by developing an online mapping service that provides a user-friendly interface for analyzing and visualizing climate information products. Use of the generated climate data and the derived information products are promoted through raising awareness in relevant communities, training users, and co-production processes.

In the former Cordex program, regional climate models were run over Africa and only covered the western part of the South Indian Ocean at a coarse 50-km resolution while a 12-km resolution was used for Europe. A 50-km resolution is insufficient for island territories as small and steep as those in the Indian Ocean. Yet this area is especially vulnerable to natural catastrophes related to the effects of climate change: it is the third region in the world most affected by extreme climatic events. The need for climate services over that populated area has now become a critical issue.

Both dynamical and statistical downscaling from a few ongoing CMIP6 simulations were therefore used to obtain regional climate information on a large area of the southwest Indian Ocean that includes most of the inhabited countries from the coasts of Mozambique (33°E) to 74°E as well as the main area of tropical cyclone genesis [2-28°S]. The limited area model ALADIN was implemented in its climate version at 12-km resolution and the first runs were coupled by outputs from one of the CMIP6 Earth Simulation Coupled Models named CNRM-ESM2-1.

We will present the numerical and statistical tools used for this regional climate study as well as the first projections obtained for ssp126 (RCP2.6), ssp245 (RCP4,5) and ssp585 (RCP8.5) scenarios over the 2015-2100 period. Results will be illustrated for the southwest Indian ocean basin as well as for the main islands of the IOC member countries: Madagascar, Reunion, Mauritius, Seychelles, and Comoros where observations over the 1981-2010 period were used for model bias correction using the quantile-quantile matching method. For climate uncertainty representativeness, the 2015-2100 evolution of both ALADIN and CNRM-ESM2-1 temperature and precipitation averages over our region will be compared to that of the other available CMIP6 simulations.

This work is part of the BRIO (Building Resilience in the Indian Ocean) project which aims at supporting the Indian Ocean Commission (IOC) member countries in the implementation of their adaptation policies with respect to climate change (regarding water resources, health and other issues). This project will provide a set of high quality climate-related data on a free-access online regional portal as well as climate services. It is funded by the Agence Française de Développement (AFD), through the Adapt’Action Facility, in cooperation with the IOC.

The aim of the Flagship Pilot Study (FPS) “Modelling the Southeast African regional Climate” is to study processes and phenomena relevant to regional climate change in south-eastern Africa. The region is vulnerable to climate change due to socio-economic factors as well as its exposure to weather and climate extremes such as floods, droughts and heat waves. The FPS will foster regional collaboration on modelling and the analysis of precipitation and temperature that will be beneficial for the society in general. The FPS South-eastern Africa includes various scientists from the National Meteorological and Hydrological Services (NMHSs) and academia of South Africa, Mozambique, Zimbabwe, Malawi, Tanzania, Kenya, Rwanda, Burundi and Norway. The research will involve analysis of local observations, reanalysis, simulations from regional climate models (RCMs) and empirical-statistical downscaling (ESD) to study dependencies between large-scale conditions and local variability in the rain and temperature statistics. The expected impacts of the FPS are skills development in data analysis and modelling, and a better understanding of regional climate that is fundamental to climate services and provides guidance to decision-makers and planners. The involvement of NMHS in the project provides access to their observational networks, whose use will assist with verification of model simulations, and also increase the value of NMHSs’ work with observations and data management. Actionable information will be extracted for decision-makers, based on a synthesis of multiple sources of information which take into account the local climate, past and future trends, models’ skill, known weather/climatological phenomena, and other geographical information. Biases between the model climate and observations will be adjusted through appropriate adjustment methods such as the Quantile Mapping approach. The work will also involve capacity building on R programming language as well as other tools (e.g. CDO, python) and use R-based shiny web applications in distillation efforts and to provide a gateway to the information embedded in complex data structures.

Flooding is a rapidly growing concern in West Africa. In 2020 alone, several hundred people died and 100 000 were displaced by the floods that occurred across the region. The floods damaged houses and crops and washed away livestock, threatening the livelihoods of millions. Niamey, the capital of Niger, experienced a record flood with the highest ever recorded water levels in nearly 100 years. Flooding is also projected to increase with climate change. One component in addressing this challenge – and a concrete way to adapt to the changing climate – is to provide operational forecasting and warning services to enable pre-emptive stakeholder action and thereby minimize damages.

Since 2018, a pre-operational flood forecasting and warning service for West Africa has been co-designed, co-developed, co-adapted, and co-operated within the FANFAR project (https://fanfar.eu/, https://doi.org/10.5194/egusphere-egu2020-7660). This study presents results from two approaches employed to assess the accuracy and utility of the service.

Firstly, representatives from hydrological services, emergency management agencies, river basin organisations, and regional expert centres in 17 countries have contributed to develop and evaluate the service. Specifically, each participating organisation was asked to test the service during the 2019 and 2020 rainy seasons, to record the most critical flood events and the extent to which FANFAR captured the location, timing, magnitude and severity of the floods. The results indicate that both the use and accuracy of the service varies substantially (e.g. from 90% correct in some countries to not even used in others). This people-centred assessment approach also provided an important opportunity to learn about the many events that occur outside of hydrometric monitoring networks, and the way in which agencies communicate flood risk information to multiple audiences for appropriate decision-making.

Secondly, we evaluated FANFAR forecasts against conventional gauge observations at key locations (e.g. Niamey). The effect of different system configurations on forecast performance was assessed (e.g. the benefit of model calibration and assimilation of gauge observations). The results likewise indicate a performance spread, and sometimes ability to capture certain features of a flood but not all. For example, for the record flood in Niamey in 2020, FANFAR managed to forecast the timing and severity level at the onset of the flood, but not the extent or long duration of the flood.

We finish off by reflecting on some challenges and opportunities for operational, scalable and reliable 24/7 weather and climate services in West Africa, with potential applicability in the global South.

Variations in water levels of the Negro River, that flows through the Port of Manaus, can cause considerable regional environmental and socio-economic losses. It is therefore critical to advance predictions for water levels, especially flood levels, to provide more effective and earlier warnings to safeguard lives and livelihoods. Variations in water levels in free-flowing river systems, like the Negro follow large-scale precipitation anomalies, which offers an opportunity to predict maximum water levels using observed antecedent rainfall. This study aims to improve the performance and extend the lead time of statistical forecasts for annual maximum water level of the Negro River at Manaus, relative to operational forecasts. Multiple linear regression methods are applied to develop forecast models, that can be issued in March, February and January, with the best possible combinations potential predictors: observed antecedent catchment rainfall and water levels, large-scale modes of climate variability and the linear trend in water levels. Our statistical models gain one month of lead time against existing models, but are only moderately better than existing models at similar lead time. Using European Centre for Medium-Range Weather Forecasts (ECMWF) seasonal reforecast data with our statistical models, further gains an additional month of lead time of skilful performance. Our models lose performance at longer lead times, as expected. Our forecast models can issue skilful operational forecasts in March or earlier and have been successfully tested for operational forecast of 2020. This method can be applied to develop statistical models for annual maximum water level over other free-flowing rivers in the Amazon basin with intact catchments and historical water level record.

The 4onse project (Four times Open Non-conventional system for Sensing the Environment) was born by the collaboration between SUPSI and two universities in developing countries namely the University of Moratuwa in Sri Lanka and the Institue of Space Technologies in Pakistan. The activities led to the installation of more than 30 stations in the Deduru Oya basin in Sri Lanka, following the development and testing of a prototype. The rise of technologies for Smart City and the Internet of Things (IoT) makes this project of interest to both the scientific and the private world, also considering the growing concern for environmental and climate issues.

The environmental monitoring system has been designed and developed on the wave of openness, which increasingly pervades not only scientific activity, but also the commercial sectors at different levels. Based on this philosophy, the selected hardware and software technologies have been evaluated in terms of quality, durability and sustainability and are showing very promising results. Unlike conventional systems, where the adoption of closed solutions strongly limits interoperability and data sharing, the designed solution is characterized by a high reproducibility and interoperability, guaranteed by the adoption of open software and standards for the collection and distribution of data. Such a technology can be applied and further developed for monitoring natural and non-natural environments that require low-cost sensor components with a level of quality comparable to conventional systems commonly used. This cost-effective solution is a possible alternative for the implementation of sensor networks in particular in low-income or developing countries in order to manage natural risks or water resources.

The solution consists of three different layers: hardware, server and communication layer. The hardware layer consists of a weather station based on Arduino and sensors measuring environmental variables. This kind of prototype has been validated thanks to the comparison of the time series with the data of an official weather station of the hydro-meteorological network of the Canton Ticino. The second layer is characterized by the server infrastructure that stores the measured data using the istSOS database management system (DBMS), which makes them accessible thanks to the implementation of open standards such as the Sensor Observation Service (SOS) of the Open Geospatial Consortium (OGC). Finally, the communication layer concerns the use of GPRS for the transmission of data from the node to the server that has been optimized in terms of energy and bandwidth consumption in order to guarantee stable and fast communication.

The research project has reached the end of the activities and during this presentation the main results and outputs will be presented.

Seasonal hydrometeorological forecasts have the potential to significantly improve the regional water management, disaster preparedness and climate proofing, particularly in water-scarce regions. They also allow for the development of forecast-based action plans for extreme climatic events like droughts and anomalous wet conditions. However, raw global products from data providers like the European Centre for Medium Range Weather Forecasts (ECMWF) cannot be directly used for regional applications due to model biases and drifts as well as a coarse spatial resolution of 35km and more. Furthermore, for transferring the information from ensemble-based forecasts into practice, we have to provide derived and tailormade forecast quantities for the water management in a user-friendly way. In this study, we hence present an operational post-processing and online decision support system with which we a) regionalize ECMWF’s latest seasonal forecast system SEAS5 through a Bias-Correction and Spatial Disaggregation (BCSD) technique, b) compute tailored forecast measures like categorical forecast and drought indicators and c) visualize this information through an online platform. As reference, we are using the offline re-run of ERA5’s land surface component, namely ERA5-Land. Our final forecast product comprises daily ensemble forecasts for precipitation, temperature, and radiation, has a spatial resolution of 0.1°, covers the whole period from 1981 to the present and is provided for several climate-sensitive river-basins including the Rio São Francisco (Brazil), the Blue Nile (Sudan / Ethiopia) and the Karun (Iran). Derived forecast quantities are operationally computed and visualized through an online decision support system, that was jointly developed with water experts from the different study regions. As both the forecast repository and the online decision support system are publicly available, they provide a comprehensive framework for demonstrating how seasonal forecasts can be post-processed and tailored for the day-to-day water management. They further allow for the training and education of local stakeholders and water experts how to deal with seasonal forecasts. Our forecasting system is already used by several authorities and weather services in Iran, Sudan and Brazil. It thereby constitutes a large step towards an improved disaster preparedness and, hence, the climate proofing of the water sector particularly in these semi-arid regions.

The rainfall regime in the Sahel region in West Africa shows a rise in the extreme rainfall occurrence. During the 2020 rainy season, floods and inundations of unprecedented magnitude have struck almost all the Sahelian countries. Despite this new trend, the local disaster management community still reacts on a response mode, based on an annually updated flood contingency plan. In this work we present the process followed to set-up an Early Action Protocol for riverine flood. Novelty and specificity of this climate service and its co-production process lies in the fact that it's not led by the climate national information providers (meteorological and hydrological agencies), but rather proposed by a user, namely Mali Red Cross Society, with the support of its partners across The Red Cross movement. Working groups (WGs) were established to co-produce the following: participatory mapping of past flood extent linked to historical river flows and vulnerability and exposure analysis for different areas, around the 2 major rivers Niger and Senegal and their tributaries; an impact-based trigger model, taking into account, on a 5 year return period basis, the available river flow monitoring historical analysis of river peaks at the main hydrological stations, the expected impact level, the derived exposure map and vulnerability index; coordination and selection of early actions and intervention map, based on priority impacts, people targeting and feasibility of actions was led by MRCS and its Red Cross partners. After reviewing available tools and capacities, the decision was made to prioritize riverine floods around the two main river basins of Niger and Senegal. In absence of suitable hydrological forecasting models, the agreement was to use the weekly monitoring of river flows and levels by the department of hydrology, combined with rainfall forecast from the Met agency. Water levels corresponding to the 5 years return periods were selected with a lead-time for action of 4 days. The civil protection directorate provided historical flood impacts. In addition, for the city of Bamako, the following actions were undertaken: geomorphometric analysis from radar and satellite imagery; participatory mapping of flooded areas and analysis of the drainage network collectors, with a focus on the state of gutter blockage; analysis of the duration of the rising water after the start of the rain and the duration of water stagnation. The work undertaken by the WGs led to critical data production needed to develop the trigger mechanism for extreme stream flows, and associated impacts, for the noted rivers, inter alia: identification of areas and households exposed to risk; determination of the thresholds required per village/commune to trigger the emergency alert; identification of upstream mitigation activities at the household level, identification of potential partners in coverage areas where cooperation and/or complementarity is needed; enhanced monitoring of the announced flood through the scientific tools available on a weekly and daily basis. The output of this work is intended to inform discussions in the region and in other regions related to sustainable and appropriate locally led co-development of anticipatory action mechanisms.

Despite an increasing recognition of the value of climate information and broader weather and climate services (WCS) for decision-making, understanding its wider dimensions for effective delivery and use remains an ongoing discussion. In particular, a focus on barriers and enablers of using climate information can be helpful for policy-directed efforts, as this underscores challenges and streamlines strategies for action. For smaller and developing countries with particular vulnerabilities to climate variability and change, and various barriers to climate information/WCS uptake, this is especially true but often limited within research. This paper addresses this research gap by offering perceptions of climate information use in the insular Caribbean. We engaged with 26 potential WCS end-users in the form of region-wide experts and decision-makers who focus on climate adaptation, disaster risk reduction, and resilience, and analysed semi-structured interview responses to understand barriers and enablers of WCS delivery and use within the region. Against a history of projectised adaptation initiatives in the Caribbean, the results highlight that while finance is critical, there is rather a range of interlinked enabling conditions necessary for the effective use of climate information. Caribbean respondents stressed the need for island-contextualised climate information and the importance of adequate human resource capacity, loud voices/climate champions, and effective political and legislative mandates for understanding and using climate information for climate-related decision-making. As well, a factor visualisation illustrates that the practical awareness of climate information for decision-making is closely tied to proactive climate champions, and that available finance should be noted within the context of donor interests. Moving ahead, it is clear that an integrated approach for effective WCS delivery and use is necessary, requiring engaged WCS partnerships amongst multiple stakeholders. The highlighting of such challenges within an under-researched area such as the Caribbean provides insights for developing adaptation strategies within the region, and can also signal critical elements relevant for other small developing countries.

Climate services provide information to help better manage climate-related risks and opportunities in different sectors around the world. This requires work at the interface between scientific research and decision-making. Studies have found that climate services are most effective when they are co-developed and co-produced with the intended users of the services. To achieve this, climate service developments often involve scientists engaging with users and potential users, which traditionally has been most productive face-to-face, at least in the early stages of engagement and co-development to build relationships.  

In March 2020, the COVID-19 pandemic dramatically restricted face-to-face engagement, particularly for international activities. Climate service providers and users had to suddenly adapt and find methods to engage with each other virtually. Here we discuss the software and methods that are being used to ensure that provider-user engagement could continue, despite international travel restrictions, with a specific focus on working with users in China as part of the Climate Science for Services Partnership China project; a collaboration between the UK Met Office and other UK partners, the China Meteorological Administration, and the Institute of Atmospheric Physics. Using examples from work on food security with the agriculture sector in Northeast China, we will showcase different climate service prototype products, such as brochures, information packs, and comic book storylines which are helping us to engage with and understand the requirements of multiple audiences despite the lack of in-person engagement.  

Through this work, we have discovered additional benefits to virtual engagement, such as more frequent interactions with users, the ability to involve participants who wouldn’t usually be able to travel to attend events, and new metrics for evaluating climate services. These benefits will likely make virtual provider-user engagement a more common tool for developing and refining climate services with international partners in the future. We hope that the tools and methods presented here will help other climate service providers to conduct productive virtual provider-user engagement in the future, both in China and in other countries around the world.
