摘要:

運用自動站6 h降水資料和NCEP/NCAR的0.25°×0.25°再分析數(shù)據(jù)，著重分析了1513號臺風(fēng)"蘇迪羅"及其殘渦影響江蘇期間強降水落區(qū)的分布特征，以及強降水落區(qū)與風(fēng)場、渦散度、水汽通量散度等要素的對應(yīng)關(guān)系。分析結(jié)果表明：強降水多分布在臺風(fēng)低層環(huán)流中心東北側(cè)，風(fēng)場圍繞環(huán)流中心非對稱分布造成輻合和正渦度在此處集中，進一步導(dǎo)致水汽在同一地區(qū)輻合，動力條件和水汽條件在同一地區(qū)疊加是強降水區(qū)位于環(huán)流中心東北側(cè)的直接原因。單一等壓面上的負散度和正渦度均可以在一定程度上指示出強降水站點位置，不同層次渦散度場的涵蓋范圍有所不同，三層算術(shù)平均后的渦散度較單一層次的指示性更為準確。"蘇迪羅"登陸后在北上過程中接近中高緯西風(fēng)帶系統(tǒng)，環(huán)境風(fēng)垂直切變逐漸增強且方向穩(wěn)定，強降水落區(qū)基本位于850 hPa至200 hPa間切變矢量的順切變左側(cè)，這一特征對判斷登陸臺風(fēng)強降水落區(qū)具有一定的指導(dǎo)意義。

Abstract:

The distribution of torrential rain caused by residual vortex of typhoon Soudelor (1513) in Jiangsu Province during Aug. 10—11, 2015 was researched in this paper based on 6-hour precipitation data and NCEP/NCAR 0.25°×0.25° reanalysis data. The precipitation distribution and its relationship to wind, divergence, vorticity and moisture flux divergence were also analyzed. The results were as follows:the torrential rain was mostly located on north-east side to the lower circulation center, where convergence and positive vorticity were concentrated because of the asymmetric distribution of wind around the center. The superposition of dynamic conditions and water vapor conditions in the same area is the immediate cause of the torrential rain area located on the northeast of the circulation center. Both of the negative divergence and positive vorticity of single isobaric surface could indicate the torrential rain location. However, the coverage was varying when the isobaric surface changed. So the average value of the variables from three isobaric surfaces worked better. While Soudelor was approaching the weaterlies at mid-high latitudes, the vertical wind shear enhanced, with stable direction. The torrential rain was mostly located on down-shear left side of the shear vector between 850 hPa and 200 hPa, which could be used to locate the torrential rain caused by landed typhoon.
