Abstract使用1987年夏季MAC-SINEcam;aign期间在挪威北部的Aneenes发射的5枚chaff火箭垂直速率数据他70-100km高度范围内大气垂直速度扰动垂直波数谱.发现垂直速度垂直波数变谱在3.9×10^-4m^-1处有1个谱缺口.
Other AbstractVertical wavenuraber spe~rum of vertical vdocity fluctuations of atmosphere at heights of 70-100km is presented using vertical velocity data obtained from five chafr rocket measurements carried out during the MAC/SINE campaign in the s1Ⅱnm日of 1987 at Andenes,in Northern Norway(69。N,16 E) The atmospheric veNcal way.1umber spee trIIrn of the vertical velodty has a spectral gap at m =3,9×10 m.At vertical wavenumbers greater than the spectral gap the vertical wavenumber spectrum agrees ~nell with the saturated spectrum mode1 At vertieal W'aV~'Klllbers smaller than the spectral gap the vertical wavenumber spectrum has a slope of--1.87 and a spectral amplitude that is an order of magnitude lower than the saturated spe~rum,suggesting that other geophysical processes besides gravit~ wav~/may exist in the vertical velodty fluctuations
