摘要：

With the CPC Merged Analysis of Precipitation (CMAP) and a gridded dataset based on the TOGA-COARE IOP in-situ soundings, we study the convective activities in the Indian Ocean-western Pacific sector. Three basic modes of cumulus heating and drying, extracted by a Rotated Principal Component Analysis (RPCA), are identified to be associated with convective types that appear under different large-scale conditions. The result underlines the importance of considering various modes of cumulus heating and drying in developing a cumulus parameterization scheme.
