In recent decades, a variety of multi-timescale, multi-faceted climate and weather extremes, including droughts, floods, wildfires, heat waves, cold spells, extreme precipitation and compound events, have been observed globally. These impactful and usually devastating climate and weather extreme events have posed severe challenges to both natural environments and human societies. The rarity of these climate and weather extremes is a fundamental feature and is driven by human-activities but also has connection with the Arctic and tropical forcing. The Arctic changes statistically indicate that a ‘new Arctic’ climate is emerging, implies great potential to change the ocean conditions, atmosphere circulations and climate patterns. The tug-of-war between contrasting effects of the Arctic and the tropics brings more challenges to the implementation of existing knowledge on the prediction on climate and weather extreme events. This session will synergize global climate community’s important and novel work on investigating, predicting and projecting these climate and weather extreme events, especially to understand the role of Arctic and tropics in these processes.
The session will use the Processes, Prediction and Projection framework to showcase the latest and most compelling research on advancing understanding and prediction of climate and weather extremes. The session will be focusing on climate and weather extremes occurring in land areas manifesting as extreme precipitation, intense droughts, and intense and sustained heat waves/cold spells, wildfires, etc. Contributions are welcome from but are not limited to novel studies on (a) characteristics and mechanisms of climate and weather extreme events; (b) impacts of Arctic and tropical climate systems and their teleconnections on the climate and weather extreme events; (c) predictions and projections on the climate and weather extreme events.
Studies addressing competing driving roles of Arctic climate changes and tropical forcing as well as isolating natural and human-driving influences are highly encouraged to contribute. We also highly encourage contributions from studies revealing new characteristics of Arctic climate changes and the impacts of interaction between the Arctic and the tropics on the climate and weather extreme events. Studies undertaking concepts, e.g. artificial intelligence, to push understanding and prediction of climate and weather extremes are also encouraged to submit an abstract.
