  1. In the second part of the paper, with employing the game reanalysis data and on the basis of the theories of the baroclinic vorticity development, this paper inferred from the dynamic analysis that the horizontal vorticity can represent the baroclinic intensity of the large - scale atmosphere, and the conversion of the horizontal vorticity converting into the vertical vorticity is actually the phenomenon that the horizontal vorticity flux of the summer monsoon owning the striking longitudinal - direction vertical structure and the strong baroclinicity, influence on the horizontal movement of the atmosphere

    在第二部分，基於第一部分的結果，本文在斜壓渦度發展理論的基礎上，用在我國季風區具有更高準確性的game再分析資料，討論分析了能代表大尺度大氣斜壓性強度的水平渦度在向垂直渦度轉化的情況，說明了此轉化就是具有明顯經向垂直結構特徵和強斜壓性的夏季風環流圈將其經向垂直剖面上的渦旋通量強迫於水平運動的現象。
  2. 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。
  3. With the research of the evolvement features of barotropic and baroclinic atmosphere flow fields, the mechanism has been studied of the formation, development and die out of the heavy rainfall which occurred in wu - han during the period of 21 - 22, july 1998. the results are shown as follows : the evolvement of the rainstorm has a close relation to the barotropic component of the real atmospheric flow filed. and the barotropic component is, to a certain degree, also responsible for the coupling characteristics of high - and low - level jets

    本文從研究大氣正、斜壓流場的演變特徵入手研究了1998年7月武漢的一次強暴雨發生、發展、消亡全過程的機理，研究結果表明： （ 1 ）未經過尺度分離的實際大氣流場正壓分量的演變與此次暴雨的醞踉、發展和消亡相對應，並且正壓分量在一定程度上反映高、低空急流耦合特徵。
  4. One is the change of the basic - state parameters ( e. g., the zonal wind field ) ; the other is existence, in the real atmosphere, of instabilities not described in our model, like for instance, baroclinic instability

    一個是基態參數（例如緯向風場）的變化；另一個在實際大氣存在的不穩定（此模式未予涉及） ，例如斜壓不穩定。
  5. The numerical experiments show that when nondimension parameter 0. 35 < 0. 65, the phenomenon of subcritical instability can exist in two - layer baroclinic atmosphere. the occurrence of subcritical instability is relative to the latitudinal gradient of coriolis parameter

    試驗結果表明：當無量綱量0 . 35 0 . 65時，斜壓兩層大氣中可能發生亞臨界不穩定現象。
  6. The result also shows, for the waves of 0. 5 k < 6, the nonlinear baroclinic subcritical instability easily occurs than the barotropic one. 2. a two - layer quasi - geostrophic model forced by surface friction and radiative relaxation is used to study numerically the phenomenon of subcritical instability in baroclinic atmosphere

    文中還指出對於0 . 5 k 6的中等波長的波動，非線性斜壓亞臨界不穩定比正壓亞臨界不穩定更易發生，這與實際大氣中的情況類似。
  7. In this paper, the interaction with the nonlinear gravitational waves in the baroclinic atmosphere, which is one of the causes of outbreak weather, is studied. there are four parts in this thesis : first, based the dynamics equations describing the fact atmosphere, we gained the mode of the nonlinear gravitational waves

    本論文根據大氣動力學原理，對中尺度動力學方程進行約化攝動，得到了大氣中非線性重力波相互作用的演變方程組，對該方程組進行了理論研究和實際大氣背景下的數值求解，結果較好地解釋了兩類重大災害性天氣形成的機理。
