Abstract:The meteorological information service system for rice in China, taking the meteorological station network as its information resources, is a system for mox-nitoring and forecasting of rice growth and yield all over the country. This system can be used to correct the mistakes, remedy the data loss and convert the calculations in the decadely meteorological data issues, to establish automatically the middle and long-range forecast equations,and to providc the servicse including data displaying, printing and plotting etc.

Abstract:The periodic analysis was conducted for the frequency of the tropical cyclones landing on China using the mathematic statistical method. The linear correlation was found between the maximum wind speed near the Center V¹, V², V³ (24hr, 12hr and 6hr before landing) , respectively, and the difference of the mean maximum wind speed (24hr after landing) and V¹, V², Vs (ΔV¹, ΔV², ΔV³) . The regression equations were obtained respectively for the tropical cyclones landing on Taiwan, Hainan, Guangzhou and Fujian provinces of China.

Abstract:In this paper! varieties of irilatorations applied to divergence calculatinn are compared. The results of mathematical deductions show that all these methods are quite identical or like, And a new correction scheme is given.

Abstract:With a concept intiated by American bio-meteorologist R. G. Steadman, the monthly mean apparent temperatures at 14p·m. in summer (Juno to Aug.) in China are calculated, and the effects of wind and air humidity on the apparent temperature are discussed. The synoptic, and climatic features of the sweltering hot in summer in the reaches of the Changjiang River and in South China are compared by analysis of the day to day apparent temperatures in the two regions.
