摘要

热带东太平洋对流组织项目使用高空部署的下投探空仪和向下指向的w波段多普勒雷达记录了哥伦比亚太平洋沿岸水域上空的中尺度对流系统（mcs）的特征。雷达显示，由冰点以上的冰晶聚集体而不是霰所主导的mcs通常被认为表明只有小雨的层状雨系统在衰减。然而，下沉探空网格显示了这一类别中更广泛的MCS类型，其中一些具有产生强降雨的浅对流。雷达难以区分不同类型的聚合体为主的MCSs。

Characterization of Convection and Rainfall Off the Pacific Coast of Colombia Using Airborne Radar and Dropsonde Data

The Organization of Tropical East Pacific Convection project used dropsondes deployed from high altitude and a downward-pointing W-band Doppler radar to document the characteristics of mesoscale convective systems (MCSs) located over the Pacific coastal waters of Colombia. MCSs dominated by ice crystal aggregates above the freezing level rather than graupel, as shown by the radar, are generally thought to indicate decaying stratiform rain systems with only light rain. However, dropsonde grids showed a broader range of MCS types in this category, some with shallow convection producing intense rainfall. The radar had difficulty in distinguishing between different types of aggregate-dominated MCSs.

期刊介绍： Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
