利用实况观测定位和强度资料、NCEP的1°×1°全球最终分析资料、NOAA周平均1°×1°海温再分析资料和FY卫星水汽图像,分析台风浣熊(0801)的环境背景条件和内核结构演变与强度变化的关系.结果表明:(1)环境风垂直切变增大至10m·s~(-1)左右与南海北部海表温度逐步减小导致最大可能强度不断降低是"浣熊"快速发展过程中断并减弱的重要外部条件;(2)卫星水汽图像显示内核结构存在眼壁破裂和复原现象,该现象精确地反映其强度变化.眼壁破裂(复原)过程导致"浣熊"减弱(增强).
利用實況觀測定位和彊度資料、NCEP的1°×1°全毬最終分析資料、NOAA週平均1°×1°海溫再分析資料和FY衛星水汽圖像,分析檯風浣熊(0801)的環境揹景條件和內覈結構縯變與彊度變化的關繫.結果錶明:(1)環境風垂直切變增大至10m·s~(-1)左右與南海北部海錶溫度逐步減小導緻最大可能彊度不斷降低是"浣熊"快速髮展過程中斷併減弱的重要外部條件;(2)衛星水汽圖像顯示內覈結構存在眼壁破裂和複原現象,該現象精確地反映其彊度變化.眼壁破裂(複原)過程導緻"浣熊"減弱(增彊).

The role phyed by environmentai background and inner core in the changes of intensity of Typhcon Neoguri is documented by using observed track data,NCEP Fined Analysis,NOAA OI SST weekly means and FY satellite water vapor images.The results show that(1)the storm weakening is closely related to the vertical wind shears and sea surface temperature.The vertical wind shears increase in magnitude to about 10m/s,and the Maximum Potential Intensity(MPI)decreases when the system moves over a cool tongue of water,the intensification comes to an end;(2)The breakdown and recoveny of eyewall revealed by vapor images,are consistent、with intensity changes.The breakdown(recovery)of eyewall leads to the storm weakening(deepening).
