AB: Predictablility of the North American monsoon circulation is investigated with the 1981-2004 hindcast suite of the NCEP CFS coupled GCM and experimental forecast runs of 60-day length for select years. The forecast runs were made in the horizontal resolution of T62, T126 and T254 to investigate the impact of the spatial resolution on the depiction of monsoon circulation. The hindcasts were made in T62 resolution. Emphasis is on the prediction of precipitation and accompanying atmospheric circulation. Also investigated is the onset phase of the monsoon over the NAME Core and Arizona /New Mexico regions. Some of these features will also be studied in high resolution simulations with the T382 CFS.
