Climate services for winter tourism in Romanian mountains

WeCTOU (http://wectou.meteoromania.ro/) which delivers climate and environmental information tailored for tourism at 160 locations in Romania is a provider of climate services developed and operated by National Meteorological Administration.  European Commission and the European Centre for Medium-Range Weather Forecasts (ECMWF) through the Copernicus Climate Change Service (C3S) have provided the financial support. WeCTOU aims to extend its climate services and in this context, we have taken into account the needs of stakeholders interested in winter tourism in Romanian mountains using observations from national meteorological network together with reanalysis and model products extracted from the Climate Data Store developed at the ECMWF. Stakeholders interested in winter tourism in Romanian mountains span a wide range of categories from central and local administration to representatives of hospitality industry and individuals. In 2019, the Romanian Ministry of Economy, Energy and Business Environment, also responsible of tourism certified 195 ski slopes located in 20 Romanian counties. We use the ensemble distribution of number of days with snow depth larger than 30 cm from future projections covering the period 2021-2040 under climate change scenarios to provide a first guess assessment of future profitability of Romanian ski resorts compared with the reference period 1976-2005. This type of indicator together with climate products related to snow making are important for identifying opportunities for future investments in winter tourism. They are also important in general urban planning for localities which have to change their profile from winter resort to one which serve guests year-round.  Especially for tourists and hospitality industry, we use future projections of indicators relative to present conditions (2021-2040 vs. 1976-2005) such as the ensemble distribution of number of days with snow layers having depths larger than 30 cm during winter holidays (22 Dec- 04 Jan). Also, we have shown how testing all these winter climate services with the interested stakeholders has guided us during the incremental developing stages to shape the final design.
