Regional model simulation of North Atlantic cyclones: Present climate and idealized response to increased sea surface temperature
[1] The influence of an increased sea surface temperature (SST) on the frequency and intensity of cyclones over the North Atlantic is investigated using two data sets from simulations with the Rossby Centre regional climate model RCA3. The model domain comprises large parts of the North Atlantic and...
