摘要:
利用卫星、雷达资料对1415号台风"海鸥"强度变化和风雨特征进行分析,结果表明:活跃的西南季风为"海鸥"源源不断地输送大量的能量和水汽,是其长时间维持台风级别的重要原因之一;随"海鸥"台风的加强到减弱,从卫星及雷达资料上均可看到,台风眼区由清晰可辨到模糊消失,结构完整到结构松散的过程;通过列举一些台风影响广西期间沿海测站的极大风速与相近时间多普勒雷达在有效测距探测到的最大径向速度进行对比,发现雷达径向速度的极值能较好反映实况极大风速;广西南部、西部强降雨主要是由台风云墙强回波和螺旋云带产生。
Abstract:
Based on the analysis of typhoon Kalmaegi(1415) by using satellite and radar data, it is found out that:the active southwest monsoon continually transported a large amount of energy and water, which was one of the most important reasons for Kalmaegi maintaining for a long time in the typhoon level; As typhoon "Kalmaegi" go through the process from strengthening to weakening, both satellite images and radar data showed that its eye area changed from clear and distinguishable to fuzzy and then disappearing, its structure changed from integrate statue to loosening one. According to comparisons between extreme wind speed of some coastal stations and the maximum radial velocity detected by Doppler radar, it is revealed that the maximum radar radial velocity could well reflect the reality of the extreme wind. Heavy rainfall in the southern and western of Guangxi was mainly caused by the strong echoes cloud wall and spiral bands of typhoon.
