本文主要研究内容
作者潘劲松,周玲丽,陆玮,罗玲,翟国庆（2019）在《两个相似路径台风残余造成局地特大暴雨的成因机制和能量收支对比分析》一文中研究指出：本文利用ERA-Interim 0.5°×0.5°再分析资料、自动站小时和分钟加密资料、风云2G(FY-2G)卫星红外云图及多普勒雷达和风廓线雷达资料对2015年路径高度相似的"苏迪罗"和"杜鹃"台风在浙江沿海引发的局地特大暴雨进行对比分析。这两次降水过程都是在台风减弱为热带低压甚至残压并深入内陆远离浙江沿海后发生的。结果表明,"苏迪罗"降水过程是由低层强东南和偏南急流长时间辐合加上有利地形共同作用导致的;经向环流背景下来自季风持续的水汽输送有利于"苏迪罗"维持较长的生命史和稳定的降水。"杜鹃"残压特大暴雨的触发系统则是高纬地面冷高压底部的东东北出流南下与"杜鹃"北象限的东东南风交汇形成的中尺度倒槽;纬向环流和强盛副热带高压造成的弱引导气流及夏季风南撤和低涡卷挟造成的水汽通道断裂是"杜鹃"登陆后快速减弱为残压和降水维持时间较短的原因。两次台风降水过程中均无外部动能输送和来自有效位能的动能转换。动能收支的主要影响因子为中低层局地次网格运动间的能量转换、旋转风和散度风效应及下垫面的摩擦耗散。所以,虽然"杜鹃"的对流有效位能很小,但仍可造成强对流和特大暴雨。此外,降水过程中释放的凝结潜热造成的局地非绝热加热使气柱中显热能大量累积,促使地面中小尺度涡旋和倒槽不断加深,造成降水的增幅。
