CHARACTERISTICS OF THE DISTRIBUTION OF TOTAL RADIATION IN CHINA

1. The authors made a review of all the known equations used to calculate the total radiation. in the foreign countries, before deducing an emperical one for China. 2. To obtain a monthly latitudinal mean of total radiation (Q+q)0 during cloud-less day for every 2.5 latitudes, data of the 26 stations in the country from July 1957 to Dec. 1960 inclusive have been used. A separate mean has been obtained for the Tibetain plateau in order to accord with its special, natural conditions. The latitudinal means show two "high belts" at 25°N and 40°N respectively and a "low belt" between them at 30°N.
