AN ANALYSIS OF “TWEEK” OBSERVED AT BEIJING

HE YOU-WEN (University of Science and Technology of China)  
The results of the statistical analysis of data on tweeks from December 1975 to August 1978 at Beijing (Geomag. Lat. 29°N) are summarized as follows: (1) virtual height is about 85 km during the day, and 100 km during the night; (2) higher order modes occurrence is less than 27% during the day -and greater than 89% during the night.
