  1. The methods reported by g. s. young in 2000, are applied on sea surface sar images featured by three dimensional convective cells. then the following parameters are retrieved from sar images : the characteristic wave length of three dimensional convective cell, the mabl depth, the vertical convective scale velocity, the surface buoyancy flux, obukhov length and the stability correction factor for sar derived sea surface wind speed

    針對海洋大氣邊界層中三維對流渦旋sar圖像，用g . s . young在2000年發表的方法，反演三維對流渦旋的特徵長度、海洋大氣邊界層高度、以及海洋大氣邊界層垂直對流尺度速度、表面浮力通量、海面風速穩定性校正因子和obukhov長度。
  2. In order to make clear the changing situation about various meteorological element fields during the heavy rain. the diagnostic analysis in three aspects was done in this text : the vapor conditions, in which the difference of the temperature and dew point, relative humidity, vapor flux and the divergence of vapor flux were discussed ; the dynamic and thermodynamic conditions, vorticity, divergence and vertical velocity were analyzed ; the vertical layer condition, which included potential temperature, static stability, convective ( potential ) instability and the vertical profile of eight physical fields over the observatory of shenyang

    為了弄清這次暴雨過程各氣象要素場的演變情況，分三方面對暴雨的水汽條件（使用了溫度露點差、相對濕度、水汽通量和水汽通量散度） 、動力條件（使用了散度、渦度和垂直速度）和垂直層結條件（使用了位溫、靜力穩定度和潛在不穩定度以及沈陽單站的8個物理量的垂直廓線）等的變化，分別進行了診斷分析。
  3. A propbr data structure is used to assist grid generation for different geometric dimensions. a concept of entropy in broad sense is proposed for convective - diffusive problems in chapter 7. it is proved that there is an intrinsic relationship between the stability of the numerical schemes of the convective - - diffusive differential equations and the non - negative property of the entropy generation caused by the effective diffusion

    第七章提出了對流擴散問題中的廣義熵概念，研究了擴散熵產非負性特徵與數值格式穩定性的內在聯系，分析證明了擴散熵產非負定性及統計非負定性的穩定性準則，探討了穩定性與模擬性之間的矛盾與聯系。
  4. The results show that there are two centers of occurrence of llsw respectively in dong bei and jiang nan ; the regional torrential rain over the yangtze river basin is closely associated with llsw during the major periods of heavy rainfall ; the diurnal variation of the number of occurrence in the middle and low reaches of the yangtze river is the strongest in china there are some significant differences between llj and nallsw in positive season, spatial variation, diurnal variation and field of pressure. by the way, the important effect of inertial stability on heavy rainfall with both low level south - westerly jet and high level northerly strong flow is analyzed theoretically. the results show that the existence of the maximum of inertial stability in the left font of the low level jet is favor of the accumulation of the moist thermal energy, and conditional symmetric instability or convective instability can be expected in this region

    另外，慣性穩定性的作用以往不受重視，本文通過對西南低空急流左前方和高空偏北大風軸右後方的慣性穩定性和對稱穩定性的理論分析和實例計算，表明慣性穩定性在伴有高低空急流的暴雨中有重要意義，揭示了梅雨暴雨的一種新的高低空急流耦合機制：低空急流左前方慣性穩定度大值區的存在，有利於低層濕熱能量的積累，使低層傾斜對流的不穩定發展更多期望于條件性對稱不穩定或對流不穩定；高空偏北大風軸（西風急流）的存在，是其右後方（右側）出現對稱不穩定的有利條件，高空相對容易出現干對稱不穩定；慣性穩定性的作用，使低層的傾斜對流更偏向於垂直方向，有利於對流發展，使高層的傾斜對流更偏向於水平方向，有利於高層輻散。
  5. Stability aalysis of the characteristic difference scheme based on the local quadratic interpolation of convective - diffusion equation
