本文根据历史资料,分析了南海北部(指15°N以北海区)冬季(12月至次年2月)海面温度变异(即多年变化)的特点。文中所用的海洋站资料取自国家海洋局海洋站月报表,部分海温资料取自中科院地理研究所和上海气象台合编的《北太平洋逐月平均海面水温资料》并补充到1980年。 Based on historical data, this paper analyzes the characteristics of sea surface temperature variability (ie, years of change) in the northern part of the South China Sea (referring to the north of 15 ° N) in winter (December to February). The ocean station data used in this paper are taken from the monthly report of the State Oceanic Administration Ocean Station. Some of the sea temperature data are taken from the “monthly average sea surface water temperature in the North Pacific Ocean” compiled by the Chinese Academy of Sciences Institute of Geography and the Shanghai Meteorological Observatory and added to 1980.
