台风登陆衰减后造成降水加强的概况
Summary of causing increase in precipitation by landfalling weakened tropical cyclone
摘要
Abstract
The landfalling tropical cyclone precipitation (TCP) during 3 d after its weakening is partitioned from the 101 landfalling TCs from 1965 to 2008 with the Objective Synoptic Analysis Technique and its improvement programs. The results show that, even if the landfalling TCs attenuate to a tropical depression or tend to be dead, high-intensity rainfall caused by the presence of the typhoon system is universal phenomenon. So it still requires a high degree of concern. The climate characteristics of TCP and TCs were analyzed with trend coefficient and power spectrum technique. The spatial distribution of TCs' weakening spots shows great regionalization, which is obviously consistent with terrain. The volume of landfalling weakened TCP does not monotonously decrease with time, and the distribution of TCP spreads westward and northward. Especially, more emphasis should be paid on precipitation from Jiang-Han to Jiang-Huai area in middle-latitude, which is the point to reduce and prevent disasters. The TC tracks of landfalling south and east China should be focused on, in order to limit the damage caused by landfalling weakened TCs.关键词
