我国东部邻海恶劣天气的时空分布及其成因初探

本文利用1930～1979年NCDC海洋船舶观测的气象资料,分析了中国东部邻海恶劣天气的时空分布。结果表明,海区恶劣天气的分布在冬季和夏季是不同的;在东北和西南季风期间,台湾东北和西南海区也有差异。影响恶劣天气条件的分布因子非常复杂,主要是季风和极锋、天气系统、冷暖洋流及地形等因子。

SPATIAL-TEMPORAL DISTRIBUTION CHARACTERISTICS OF POOR CONDITION OVER THE EAST CHINA SEA

The spatial-temporal dictribution of poor condition over the East China Sea and the major cause formation are analysed ky using ship data from NCDC during the period of 1930-1979. The result shows that there is difference in poor condition distributions between winter and summer, and that there is differnce also between the northeast and southwest of taiwan during the period of prevailing NE monsoon and SW monsoon.The factors effecting poor condition over the East China Sea are comparative complex, of which the major may be related to monsoon, polar front, wheather systems, and sea currents.
