Abstract

The first weather radar campaign over Lima, the capital of Peru, a desertic area on the western side of the Peruvian Andes, was carried out to study the occurrence of rain events in summer 2018. The weather radar was installed strategically and was able to overlook three river basins: Rimac, Chillón, and Lurin. An X-band radar (PX-1000) was used, which operates at 9.55 GHz. PX-1000 was built by the Advanced Radar Research Center (ARRC) at the University of Oklahoma (U.S.A.). The radar operated from January 26th to April 1st, 2018, at Cerro Suche located 2910 m ASL and 55 km from the city of Lima. The PX-1000 performed plan-position-indicators (PPI) for elevations starting at 0° up to 20°. The data presented here were obtained using a three-dimensional constant-altitude plan-position-indicator (3D CAPPI), which was generated by high resolution (250 m) nearest point algorithm.

摘要

首次针对秘鲁首都利马开展的气象雷达观测活动在秘鲁安第斯山脉西侧的沙漠地区进行，目的是研究2018年夏季降雨事件的发生情况。气象雷达安装位置经过精心规划，能够俯瞰里马克、奇隆和卢林这三条河流域。使用的是一台X波段雷达（PX - 1000），其工作频率为9.55吉赫兹。PX - 1000由美国俄克拉荷马大学的高级雷达研究中心（ARRC）制造。该雷达于2018年1月26日至4月1日在海拔2910米、距离利马市55公里的苏切山运行。PX - 1000对仰角从0°到20°进行平面位置指示（PPI）扫描。此处呈现的数据是使用三维等高平面位置指示（3D CAPPI）获得的，它由高分辨率（250米）最近点算法生成。
