doi: 10.1007/BF02690792

  • Using the dataset of 1998 TIPEX, the data of 6 automatic heat balance observational stations (AWS)from May to August 1998, a dataset of 52 surface observational stations over the Tibetan Plateau (TP)and its adjacent region, the daily rainfall amounts from about 300 stations in China, the outgoing longwaveradiation (OLR) data received by the National Satellite Meteorological Center(NSMC) of China, and TBBdata from GMS remote sensing of Japan, the characteristics of the seasonal variation of the surface totalheating over TP and its surrounding area in summer 1998 and its relationship with the convection overthe subtropical area of the western Pacific is studied in this paper. The results show that the surface totalheating over TP had a close relationship with the onset of the rainy season, and after the onset of the rainyseason, the regional mean surface total heating over TP decreased distinctly. Furthermore, the regionalmean surface total heating over TP had very good negative correlation with TBB over the subtropicalarea of the western Pacific along 20-30°N, which shows that the surface total heating over TP was able toaffect the convection over the subtropical area of the western Pacific.

Abstract: Using the dataset of 1998 TIPEX, the data of 6 automatic heat balance observational stations (AWS)from May to August 1998, a dataset of 52 surface observational stations over the Tibetan Plateau (TP)and its adjacent region, the daily rainfall amounts from about 300 stations in China, the outgoing longwaveradiation (OLR) data received by the National Satellite Meteorological Center(NSMC) of China, and TBBdata from GMS remote sensing of Japan, the characteristics of the seasonal variation of the surface totalheating over TP and its surrounding area in summer 1998 and its relationship with the convection overthe subtropical area of the western Pacific is studied in this paper. The results show that the surface totalheating over TP had a close relationship with the onset of the rainy season, and after the onset of the rainyseason, the regional mean surface total heating over TP decreased distinctly. Furthermore, the regionalmean surface total heating over TP had very good negative correlation with TBB over the subtropicalarea of the western Pacific along 20-30°N, which shows that the surface total heating over TP was able toaffect the convection over the subtropical area of the western Pacific.
