摘要
本文采用60°E—160°E,60°N—5°S范国内,1000hpa至300hPa各标准等压面上经纬格距均为2.5°φ的格点场资料,计算了:(1)1991年两段梅雨期内(5月21日—6月19日、6月28日—7月15日)水汽总输送量,水汽涡动输送量,平均经向、纬向水汽输送量等;(2)固定区域(117.5°E—122.5°E、30°N—35°N)内务标准层上三段(加入梅雨中断期6月20日—6月27日)内东、西、南和北各剖面上水汽输送量及水汽收支;(3)固定区域内各剖面上整层的水汽输送和水汽收支的时间分布后,得出了一系列有意义的结果。
In this papdr, the grid data in the standard isobaric surface layers from 1000 hPa to 300 hPa were used, with the range of 60E- 160E. 60N-5S, and their latitudinal and longitudinal grid lengthes were 2.5. We have calculated that: 1. the values of water vapor transfer (WVT) , the eddy WVT, the average longitudinal and latitudinal WVT during two Mei-Yu periods in 1991 (5.21-6.19, 6,23-7.15); 2. the values of WVT and water vapor balance of income and output at the every layer in the cast, the west, the south and the north sections over the fixed region( 117.5 E-122.5E, 30N-35N)during the three Mei-Yu periods (including the Mei-Yu interval period6.20 -6.27); 3. in the fixed region, the distribution of the avcraeg values of WVT and the water vapour income and output over all layers (integration the values of every isobaric surface layer from 1000 to 300hPa ) in each section with time, and have obtained a Series of significant results.
