摘要
热带气旋是影响南海地区的主要灾害性天气系统。每年热带气旋频繁地袭击南海,威胁着南海石油平台的正常作业。本文利用1949-1986年间的气候资料,对位于21°10′N,115°50′E的南海石油平台海域的热带气旋的气候学特征进行分析研究,找出热带气旋的源地、强度、频率、移速、移向、季节变化和年变化,大风以及路径分布等气候特征,为石油平台安全作业的海洋水文要素的计算和热带气旋的预报提供有用的气候背景。
This paper aims at studies on the climatological characteristics of tropical cyclones (TC) which affected the platform located at 21°10/N, 115°50/E, and its surroundings by using historical data from the period 1949-1986. It covers the origin, intensity, frequency, speed, direction, seasonal and annual variations and the characteristics of gales, as well as the path distribution of TC. This analysis and the conclusions derived, not only make calculation of marine hydrological elements possible to render safety to the operation of platforms against TC attacks, but also provides climatological background for the prediction of TC.
