RESEARCH OF THERMAL CONVECTION OF THE HEXI CORRIDOR IN GANSU PROVINCE OF CHINA

Abstract

Ten years abstract data of twelve surface synoptic and aerological stations in the Hexi Corridor region of China having been analysed, it is concluded that thermal updraft is rather intense in summer, more so in the west part than in the east. Further, soaring flight may be carried out from March to September every year; the better period is from May to August. The best month is June. These conclusions are supported by the experiences of soaring flights on the Jiayuguan region of the Hexi Corridor in summer of 1984, 1985 and 1986, where climb rates are usually 2-3 m/s, or even 5-6 m/s, and occasionally reach 8-10 m/s. Finally, it is concluded that the west part of the Hexi Corridor is a good training and competition base for soaring flight; may be it is the best place for creating a new world record.
