利用海骚回波推测海面风浪

UTILIZATION OF THE SEA CLUTTER ECHOES TO INFES THE SEA SUSFACE WINDS AND WAVES

摘要:

本文研究海骚回波最大距离与海面风浪的关系。由汕头雷达站1983年9月至1984年12月探测得到的130个海骚回波个例,与来自东山、南澳和遮浪站以及部份船舶记录相应的风资料进行对比分析,建立了海骚回波与1小时内海面风及前6小时海面风的2个线性回归方程,其平均绝对误差分别为1.23米/秒和1.36米/秒。另外,通过风浪关系,建立了一条海骚回波相应海浪高度的关系曲线。它们基本上能满足海洋气象服务的需求。

Abstract:

This paper investigates the relationships between the maximum distances of the sea clutter echoes and the sea surface winds and waves. 130 of the sea clutter echoes cases from September 1983 to December 1984 which were examined by Shantou Radar Station. There were correlative wind date from Dongshan, Nanao and Zhelang Station and shipping records. Through contrast analyses, two linear regression equations were found,which said that the sea clutter echoes correspond with about sea surface winds in previons one and six hours, their average absolute errors being 1.23 m/s and 1.36 m/s respectively. Besides, through studying relationships of the sea surface winds with the waves, a relative curve is established, which says that the sea clutter echoes correspond with the sea wave heights. They can basically satisfy demands for the marine meteorological service.
