Abstract:
With the Outing Longwave Radiation (OLR) data sets observed by the NOAA satellites, the diagnostic analyses of the OLR characteristics over the tropical and subtropical regions and its (impacts) on the unusual weather processes in China in the summer of 2003 are done. The results show that the ITCZ distributing over the Bay of Bengal and the Arabian Sea are stronger than (usual), while that over the South China Sea is weaker than (usual) in the summer of 2003, the anomalous OLR in the east of the Philipine Islands is anomalously higher than (usual), the anomalously inactive convective region is the main factor leading to fewer typhoons than (usual). Moreover, the subtropical Anticyclone in the West Pacific Ocean described by the area in which OLR is more than 250W·m(-2) is characterized by the relative stability in the north-south direction and the oscillation in the east-west direction, which is one of the primary reasons causing the higher temperature over South China in the summer of 2003.
