INCONSECUTIVE “SANDWICH STRUCTURE” PATTERN FOR HIGH TEMPERATURE WARM WATER IN THE WESTERN PACIFIC WARM POOL

HUANG Fei; ZHANG Lei; FAN Ting-ting; Bin WANG

Abstract:

An inconsecutive high frequency distribution with a“sandwich structure”pattern for high temperature warm water warmer than 29℃ in the western Pacific warm pool (WPWP) was found using Tropical Rainfall Measuring Mission (TRMM) sea surface temperature (SST) data, a relatively high resolution data for space. This phenomenon only shows up in boreal summer (June to September), and becomes obvious when WPWP SST is higher than 29℃. As observed, East Asian summer monsoon (EASM) impinges on Philippine Islands in July, which has an important impact on the formation and maintenance of the “sandwich structure”. Winds affect the distribution of SST in two ways: one by increasing the local latent heat flux and the other by transporting cold water towards the southeast of Philippine Islands.
