Abstract:In this paper, the status and prospect of remote sensing technique of meteorological satellite have been described. The condition of remote sensing imformation from meteorological satellite in next decade has been predicated. By the development of meteorological satellite technique and the improvement of imformation treatment capability, the research of some branchs of meteorology would be urged forward, for example, weather forecasting,climate and long range weather forecasting,atmospheric exploration (include clouds and rain), atmospheric pollution, marine environment and snow-ice. Meteorological satellite remote sensing supplys a demand of comprehensive survey of earth environment, in this paper, this item has been discussed also. The last, we make an overview of the satellite meteorology activity in China.

Abstract:In this paper,five squall cloud patterns and evolutive forms of their cJoud systems: are given. A conceptual model of their forming and developing is presented. It has been attempted to recognize and forcast squall-line weather with satellite cloud image. Some relations between mesoscaie severe' convective cloud regions and weather scal.e cloud system are discussed. -

Abstract:A diagnosis scheme of very-short-range regional heavy rain in central China is clarified- In the scheme, each term of wet-potential tendency equation is given a weight according to the weather system, which may cause heavy rain. With the aid of the equation, forecast of the system behaviors can be made, and the area of heavy rain can be determined by use of no-heavy-rain index.

Abstract:In the summer of 1982,the first atmospheric science investigation had been performed in Xian, using an aircraft installed with PMS instruments. The case analysis of aerosol particles observation under fine weather condition is presented in this paper based on the data of 8. June The results show that the concentration of aerosol particles (0.5-8°m diameter) ranges from 4×10⁰-3.8×10¹/cm³, decreases with inereasing height.The temperature inversion layer has obstructive effect on the vertical transportation of aerosol particles. The particle size distribution expression and its parameters are given.

Abstract:Based on the results of field experiment and the meteorological data by predecessors, using Penman's formula and the theory and method of potential productivity of climate, the evaluation on the water condition of winter wheat in Cangzhou egion is analysed. The productive efficency of irrigated water in different period is investigated in theory. The results show that the water condition is better beforewin-ter, yet water supply after the reviving is out of proportion to water requirement, . an amount of water deficit is about 88-138mm in each growing period, the yield decreased about 18-50%The effect of irrigating on the increased yield is the best at jointing-earing stage under the same irrigated quantity, the increased yield is more 40.6% and 18.3% than the stages of reviving-jointing and earing-ripening respectively.
