【摘要】 <正> 中太平洋西部赤道附近地处低纬,属热带海洋区域,温度高,蒸发量大,是地球大气中水分和热量的主要源地之一。由于热带天气的变化,对推动和调整全球大气环流具有很大的作用和影响,而热通量变化是被看作海洋-大气间的反馈过程中重要的一个过程。海气界面热量交换是剖析海气相互作用机制的一个重要环节。就海气界面热量交换而言,许多作者已经作了大量研究。但对中太平洋西部海区来说,研究尚少。本文,拟就中太平洋西部赤道附近产生的天气与海气热交换关系进行初步分析。更多还原

【Abstract】 The chinese research vessels "Xiang Yang Hong No.9." and "Shi Jian" carried out the GARP in 0-5°N, 160-165°E (study area I) during Jan.5 to Feb. 13, 1979 and May 1 to June 8 1979, in 5°N-10°S, 170-175°E (study area II) during Jan. 14 to Feb. 13 and May 9 to June 8, 1979 respectively. Four main weather processes appeared during this survey. In this paper, the auther first describes the circulation and the atmospheric characteristics occurred in these four weather processes, then the conclusions are, 1) In study areas I and II, heat was transported from the ocean to the atmosphere from January to February and May to June. And the transport amount in January to February is greater than that in May to June, i. e. The heat transport amount from the ocean to the atmosphere of northern hemisphere within the study area I in the winter (Jan. to Feb.) is greater than that in the summer (May to Jan) but the amount of southern hemispher within the study arer II in the summer (Jan. to Feb.) is greater than that in the winter (May to June). 2) The total amount of the surface effective backradiation Qe, the latent heat flux Qv, and the sensible heat flux Q_k is positive, i. e. the atmosphere got heat from the ocean, and the contribution of the latent heat was most obvious. The transport amounts of study areas I and II are in 78.4% and 80.5% of the total respectively. 3) The air-sea heat interchanges are different in the four different weather processes. 4) During the period controled by the northeast trade heat was transported from the atmosphere to the sea surface about 23% and 38% of the time in study areas I and II respectively.更多还原
