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、本文首先探讨了由多普勒天气雷达提供的垂直风廓线产品(VWP)计算风暴相对螺旋度(SRH)的方法和步骤。
4、详细介绍了基于VAD技术的垂直风廓线产品（VWP）的应用技术，此产品对确定热力平流类型、垂直风切变等都是有用的。
