The amount, intensity, and phase of precipitation in the Arctic play critical roles in terrestrial and ocean systems and can have significant impacts on infrastructure, human activities, and livelihoods. Climate models project increased precipitation, more extreme precipitation events, and a higher frequency of rain on snow events. Observational studies indicate these changes may be happening already. This session will bring together atmospheric scientists, observationalists, modellers, and remote sensing specialists working towards measuring and understanding current Arctic precipitation and precipitation regimes. This includes predicting future conditions, working with Indigenous Peoples and Arctic communities in research, and collaboratively studying the impacts resulting from altered precipitation patterns, such as the increased occurrence of rain on snow events and flooding.
