My project aims to understand what controls the behaviour of Arctic low-level clouds, how their behaviour may change in the future, and what impact any changes will have on the climate of the Arctic. This involves using models to simulate Arctic clouds and their interactions with sea ice and aerosol sources; analysing field measurements to test models; simulating how the clouds respond to reductions in sea ice cover; and exploring the effect of new understanding and improved modelling capability on Arctic climate.
Clouds are a key source of uncertainty in global models and that limits our ability to predict climate forcings and associated warming. This is especially important in the Arctic, where temperatures are rising twice as fast as the global average. Unlike clouds at other latitudes, Arctic clouds have a net warming effect so it's crucial to get them right in the models.
