摘要
Time variations and large-scale features of South America summer monsoon are characterized by an index based on the first combined EOF of anomalies of precipitation, specific humidity, air temperature, and zonal and meridional winds at 850 hPa. This index describes intraseasonal to interannual variations of the monsoon. Copyright (C) 2007 Royal Meteorological Society
