Hydroclimate: Understanding rainfall extremes

Warming induced by greenhouse gases will increase the amount of moisture in the atmosphere, causing heavier rainfall events. Changing atmospheric circulation dynamics are now shown to either amplify or weaken regional increases, contributing to uncertainty in future precipitation extremes.

Causes of change in Northern Hemisphere winter meridional winds and regional hydroclimate

Improved mechanistic understanding of greenhouse gas-induced change in Northern Hemisphere atmospheric circulation reveals a tendency of models to overestimate future mid-winter rainfall along the North American west coast.
