Impacts of Soil Moisture on GCM Forecasts

Impacts on Precipitation Forecast
Impacts on Temperature Forecast


Description
   
To examine the impact of pre-existing soil moisture anomalies on the climate forecasts, two ensemble runs (10 members each) with the CPC's seasonal prediction model have been carried out. The first one (control run) initializes with climatological soil moisture and the second (SM run) has the most recent soil moisture anomalies obtained from the dataset of Huang et al.(modified so that the anomaly has the Reanalysis soil moisture's interannual variability). The impact of soil moisture on the climate of ensuing seasons is shown as the difference between the two ensemble runs (SM - Control).
