简介：在华南海(SCS)的海条件的统计描述被分析调查一30年(1976-2005)每天数字地模仿了波浪高度和风速度数据。月刊这些参数的变化显示出那波浪高度和风速度有最小在12月分别地在5月和2.04m和8.12ms1,的山峰价值分别地0.54m和4.15ms1,珍视。高度和风速度和年度、季节、每月的吝啬的海的随后的描述基于这些说的每日的波浪的统计分析参数也是做。结果出现那一般来说，细微的海国家在SCS占优势并且将近在所有季节和月有最高的出现。当时，中等的海条件在12月和1月的冬季月内占优势光滑(小浪)海状态在5月占优势。而且，海状态的空间变化显示出那平静并且平静的海面条件在南部的SCS有高出现(25%-80%)。细微的海条件在SCS的大多数部分上显示出最大的出现(25%-55%)。不平、很不平的海的高出现(8%-17%)在中央SCS在一些区域上散布。到非凡的条件的从高度的海状态显示出稀罕出现(<12%)在北SCS。平静(玻璃质)海状况不在SCS显示出出现。
