This paper analyzes the position and function of the meteorological work in the whole national economy construction,
studies the concept, classification and characteristics of the meteorological service, focuses on the basic thoughts of the
benefit valuation of profession meteorological service, determines the basic methods of studying the high
meteorology-sensitive industry, analyzes the basic methods of determining the profession annual value ratio of
production occupied by the high meteorology-sensitive industry. Based on the above works, the Chinese high
meteorology-hypersensitive industry is put forward, the benefit of meteorological service of the typical operation of the
high meteorology-sensitive industry is analyzed, the profession annual value ratio of production occupied by the high
meteorology-sensitive industry is obtained, and the benefit of the national profession meteorological service is initially
assessed through the expert valuation method (Dephi method). At the present level of meteorological service and
economic development, the annual mean efficiency of meteorological service is no less than 279 billion 3 million
yuan.( The cost is not included.)
Climate yield potential is known to be under great effect of climate factors. Based on multi-yearly climate records and agrometeorological observations and by means of the scheme for calculating yield potential (YP) proposed by Huang Bingwei the authors investigate the distribution of mean climate YP for several representative stations in Henan and averaged availability of climate resources for staple crops in this province, and with Zhengzhou station as the typical station, calculated is made of annual YP of photosynthesis, light-temperature, and light - temperature- water and also YP of wheat and corn related to the above three factors. Wavelet analysis shows that on an annual basis, the photosynthesis YP has quasi-8 yearly periods, light-temperature YP gives quasi-8 and quasi-4 yearly periods, and light- temperature-water YP exhibits quasi-6 and quasi-10-yearly periods. Study is also undertaken of availability of climate resources by wheat and corn in the year and their growth season. Finally, analysis is done of effects of meteorological factors upon yields of the staple crops as well as their availability of the climate resources.
