摘要:
利用常规观测资料、NCEP、地面自动站等资料,对1330号台风"海燕"在冷空气影响期间物理量场的变化特征开展诊断分析。结果表明:冷空气侵入台风环流的西部触发不稳定能量释放,促进台风暴雨的增幅;位涡和散度垂直剖面分析表明一定强度的冷空气侵入使得气旋性环流有所增强;925hPa的水汽通量散度负值区对其强降水落区有较好的指示意义。
Abstract:
Based on conventional observation data and NCEP reanalysis, encrypted automatic meteorological station, and so on, the physical diagnostic quantity of No. 30 typhoon "Haiyan" invaded by cold air in autumn were analyzed. The result shows that:the cold air invading the west of typhoon circulation triggers the unstable energy releasing to promote the increase of Typhoon Rainstorm; Analysis on profile of PV and divergence show that the cyclonic circulation is stronger after the intrusion of cold air. The negative region of water vapor flux divergence at 925 hPa can indicate the heavy rainfall position.
