摘要:

利用 2012 年 8 月 2 ~ 3 日高空、地面常规资料以及 FY - 2D 卫星云图,从环流形势、物理量场、卫星云图等方面探讨 2012 年 10 号台风“达维”对日照“08. 03”暴雨天气过程的影响。结果表明:本次台风暴雨是由“达维”气旋性涡旋自身动力上升造成的。强降水主要发生在高能舌附近和台风移向的右前方;水汽通量中心区、水汽通量散度负值影响区、垂直速度强上升区对应强降水区;日照上空强烈的低层辐合和高层辐散十分有利于强降水的产生;台风“达维”的不对称结构是强降水出现在日照的重要原因,强降水云系位于台风移向的右前方,TBB、OLR 低值中心对应强降水中心。

Abstract:

Based on the aerological sounding and surface data and FY - 2D satellite data from 2 to 3 August 2012,the influence of
“Damrey”typhoon on rainstorm process occurred in Rizhao of Shandong Province on 3 August 2012 was analyzed from the circulation
pattern,physical quantities and satellite image. The results showed that the rainstorm was caused by the cyclonic vortex of“Damrey”
typhoon risen up on its own motive power. The rainstorm area mainly located at the front right side of typhoon moving direction and near
the high energy tongue. The centre of vapor flux,negative value area of vapor flux divergence and strong rising area of vertical speed
was corresponding with the strong rainfall area. The pattern of low level convergence and high level divergence over Rizhao was benefi-
cial to the maintenance of rainfall. Furthermore,the asymmetric structure of“Damrey”typhoon was a important cause of the rainstorm
appeared in Rizhao,The cloud system of strong rainfall located at the front right side of typhoon moving direction,and the central of
strong rainfall was overlapped with the low value center of TBB and OLR.

Key words:  typhoon, rainstorm, causes analysis
