THE CHARACTERISTICS OF WINDS AT HEIGHT OF 20-80km IN THE CHINESE AREA

Some characteristics of winds at height of 20-80 km in the Chinese area areobtained using the Nimbus-7 SAMS temperature data from 1979 to 1981 by thegeostrophic balance thermal wind equations. It is shown that the winds from satellite are coincident roughly with the winds from Chinese rocket measurements andthe derivation of winds with the satellite temperature data is effective in obtainingclimate characteristics of winds at height of 20--80 km in Chinese area. These results show the difference between the zonal mean winds above China with the zonalmean wind of CIRA-1986 is obvious. The longitudinal difference of the winds atheight 20--80km over China is also evident. The effect on the middle atmospherewinds by topography of this area can not be disregarded. The meridional wind andvariations of winds over China is discussed.
