ANALYSIS AND FORECASTING OF SUMMER WEATHER OVER AND IN THE NEIGHBORHOOD OF SOUTH CHINA

Abstract

A brief history is given of summer weather forecasting for south China and its neighborhood, as practiced in Hong Kong, underlining the failure of frontal and air-mass methods of analysis to provide workable models. By re-analysis of 1948 and 1949 data for 10,000 ft, flow-rainfall-distribution relationships have been found, enabling summer situations to be classified under four main headings. A discussion of the types includes sample situations, relating l0,000-ft streamlines to rain distributions, and sections on frequency variations during the summer months. Finally, common sequences of the various types are described.
