1、A method and steps of calculating storm relative helicity (SRH) according to the Doppler radar vertical wind profile (VWP) products are discussed firstly in this paper.
2、The product of vertical wind profile(VWP) which based on VAD methods are introduced detailedly. This product is useful to ascertain the type of thermal advection, the shear of vertical wind, etc.
3、本文首先探討了由多普勒天氣雷達提供的垂直風廓線產品(VWP)計算風暴相對螺旋度(SRH)的方法和步驟。
4、詳細介紹了基於VAD技術的垂直風廓線產品（VWP）的應用技術，此產品對確定熱力平流類型、垂直風切變等都是有用的。
