Abstract

Abstract Airborne in situ measurements of updrafts in tropical convective storms were analyzed to determine the similarities and differences between updrafts in a tropical continental and a tropical oceanic region. Two hundred fifteen updraft cores from the Tropical Rainfall Measuring Mission (TRMM) component of the Large Scale Biosphere–Atmosphere (LBA) experiment (tropical continental wet season) and 377 updraft cores from the Kwajalein Experiment (KWAJEX) (tropical oceanic) were analyzed in a similar manner to that of previous studies of tropical updrafts. Average speed, maximum speed, width, and mass flux of the updraft cores from the TRMM-LBA and KWAJEX were generally similar to each other and also were similar to results from previous studies of tropical updrafts.

热带太平洋中部和亚马逊地区降水系统中强上升气流的特征
摘要分析了热带对流风暴上升气流的航空原位测量结果,以确定热带大陆和热带海洋上升气流的异同。采用与以往热带上升气流研究类似的方法,对来自大尺度生物圈-大气(LBA)实验(热带大陆湿季)热带降雨测量任务(TRMM)组成部分的215个上升气流核和来自夸贾林岛实验(KWAJEX)(热带海洋)的377个上升气流核进行了分析。TRMM-LBA和KWAJEX的上升气流核心的平均速度、最大速度、宽度和质量通量大致相似,也与以往热带上升气流研究的结果相似。
