To the large - scale atmosphere, we separate the terms of the horizontal vorticity converting into the vertical vorticity, which considered as the baroclinic terms, from the terms that not including horizontal vorticity by the rules of the p coordinate transforming to the z coordinate in the traditional vorticity equation, and carry out the scale analysis, and then conclude that the baroclinic terms are able to reach the same magnitude grade as the partial derivative of the vertical vorticity to time when it takes place the large scale precipitation in the summer monsoon period in china. by analyzing the game reanalysis data from april to august in 1998 in the region of chinese continent, we found that the baroclinic terms is important to the large - scale cyclone developing above the 600hpa, and the magnitude changing of the baroclinic terms is nearly in - phase as the monsoon movement, so which imply exactly that the magnitude changing of the baroclinic terms is the one of the natural characters of the summer monsoon evolution and equivalent to the movement rule of the subtropical high of the western pacific
在p坐標垂直渦度方程中，利用p坐標向z坐標轉換的公式將水平渦度向垂直渦度轉化的所有項分離出來，這些項具有明顯的斜壓特徵，對其進行尺度分析后，得出在可以忽略潛熱釋放對渦度影響的對流層中、高層，此轉化項是大尺度斜壓渦度發展的重要項。通過對1998年48月的game再分析資料進行實際計算也發現，轉化項在東亞夏季風上升支的600hpa及以上層次對垂直渦度的局地變化貢獻很大，不能忽略。同時發現水平渦度向垂直渦度的轉化在南海季風爆發時和江淮梅雨入梅及發展過程中均有指示性意義，在南海季風爆發以後，在中國東南部地區，轉化項的大小與夏季風的活躍和中斷等活動有著幾乎一致的變化規律，這從側面也指出了，此轉化項的變化是夏季風演變所具有的本質特徵，並且它反映出了西太平洋副高在中國大陸的活動情況。Response of sediment flow behavior to storm type and spatial scale in purple soil watershed
紫色土區小流域泥沙輸出過程對雨型和空間尺度的響應This work aims at studying multi - scale structures of large - scale stratiform precipitating clouds typical of henan province of central - eastern china in spring and autumn drought periods of china, the potentials and techniques of artificial rain increase. through analysis of historical weather / climate and cloud physical data, developed are a number of multi - scale observational schemes including intensive observational items, and space / time resolutions of data for integrative field observations to obtain real - time measurements of the structures at large -, medium -, small - and micro - scale. from analysis of observed separate items, their integrative treatment and numerical simulation we place focus on case studies and their integration in investigating such structures of stratiform precipitating clouds over the target region, rainfall physical mechanisms and exploitation of artificial rainfall increase potentials, whereupon a conceptual model is constructed and a range of catalysis schemes are proposed to improve smaller - scale forecasting accracy and techniques for the rainfall increase, with the dominant results given below
