中国地区20—80km高空风的一些特征

利用Ｎｉｍｂｕｓ－７卫星１９７９－１９８１年的平流层和中间层大气温度探测数据和热成风原理，计算了高空风场，得到中国上空２０－８０ｋｍ高度范围风场的一些特征。结果表明，用地转－热成风公式从卫星温度探测数据计算的高空风与当是口国气象火箭探测的高空风基本一致，说明利用卫星温度数据是获得中国２０－８０ｋｍ高空风气候特征的一种有效的方法；

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.
