Using the hourly data of the 21 automatic meteorological stations in suzhou the effect of typhoon matsa on suzhou is analyzed and compared with the typhoons 9015 and 9711 in the landing strength , the route after landing , the lasting time , rainfall and wind force 摘要利用全市21個自動氣象站的逐時資料,分析了臺風(fēng)“麥莎”對蘇州市的風(fēng)雨影響,并將其與20世紀90年代以來對蘇州造成嚴重影響的9015號和9711號兩個臺風(fēng),分別從登陸時強度、登陸后移動路徑、影響蘇州市的持續(xù)時間和形成的風(fēng)雨實況等方面進行了對比分析。
Detailed diagnoses is made on a heavy - hard rain in the northeast qinghai - xizang plateau using ncep data of 1 x 1 with 6h intervals , more complete and integrated conventional observational data and the data set of automatic meteorological stations in plateau and new generation doppler radar data and satellite images and etc . the following conclusions can be drawn : 1 . the distribution of heavy - hard rain , which is characteristics of valley topography in northeast qinghai - xizang plateau is obviously effected by topography . the distribution of yearly mean precipitation and the frequencies of heavy - hard rain in this area are descending from east to west 本文首先利用ncep時間間隔為6小時的1 1的格點資料、更全面、更為完整的常規(guī)探測資料和高原地區(qū)布設(shè)的自動氣象站資料、新一代多卜勒天氣雷達資料、衛(wèi)星云圖資料等對高原東北部地區(qū)大到暴雨的天氣、氣候特征及大尺度環(huán)流背景進行分析,形成對高原暴雨的整體認識,并為以后的數(shù)值模擬提供大尺度環(huán)流背景及依據(jù),分析中發(fā)現(xiàn): 1 、高原東北部地區(qū)大到暴雨的分布明顯受到地形影響,年降水量和大到暴雨次數(shù)自東向西呈階梯性遞減趨勢,分別在高原東北部的外流河谷地區(qū)和四川北部地區(qū)存在大值中心。
