The climate sensitivity with uniform increased SST

In this study the GFDL HiRAM model is used to examine the regional climate sensitivity to increased global mean SST. Monthly HadISST data with uniform 2 degree C increase is applied for experiment. The result indicate that hydrologic cycle is strengthened as expected. Responds of precipitation is vary in Pacific. The ITCZ and SPCZ are strengthened in precipitation, but significantly weakened in the tropical western North Pacific in JJA. The high level in tropical is the most warmer region. Which also stabilized the tropical atmosphere. This is due to the stronger moisture convection. Tropical cyclone activity will be compared in this study.
