Temperature, humidity, geopotential heigt, zonal and meridional wind and vertical velocity; time resolution 6 hrs
Magnitude of the wind (m/s). Difference between reference climatology (1983-1990) and scenario (2071-2073).
Monthly average daily accumulated precipitation (mm/day). Difference between reference climatology (1983-1990) and scenario (2071-2073).
Mixed layer heigth (m). Difference between reference climatology (1983-1990) and scenario (2071-2073).
Conclusions In agreement to the experiment on the future:
wet season dry season
Temperature higher same
Magnitude of the wind
same same
Precipitationhigher same
Soil moisture same higher
Mixed layer heigth
