子午工程首次火箭探空数据准单色惯性重力波特性分析

中文摘要英文摘要

利用2010年6月3日子午工程首次气象火箭探测的温度和风场数据,采用矢端曲线法分别从平流层(20-50 km)和对流层(0-15 km)廓线提取了海南火箭发射场上空准单色惯性重力波参数。火箭探测的平流层(对流层)准单色惯性重力波向上(向下)逆风传播,固有周期为20.1 h(22.4 h),垂直波长为9.5 km (4.0 km),水平波长为2900 km(753 km),垂直群速度 为0.0887(0.0298)m/s,水平群速度 为12.7(3.65)m/s, 为305:1(188:1),前者约为后者1.62倍, 为143:1(122:1),前者约为后者1.17倍。受背景风影响, 与 差别较大。

Wind and temperature data detected by the first meteorological rocket of the Meridian Space Weather Monitoring Project was used tostudy quasi-monochromatic inertia gravity waves over Hainan rocket launch site(19.5N,109E).The GW extracted from the stratosphere (troposphere)revealed by rocketsonde is upward(downward) GW,both propagate against the background wind.The intrinsic period, vertical wavelength horizontal wavelength vertical group velocity ,and horizontal group velocity of Stratospheric(Tropospheric)GWare 20.1 h(22.4 h),9.5 km(4 km), 2900 km(753 km) ,0.08870.0298m/s,and12.73.65m/srespectively. There is a significant difference between and because of the background wind. The ratio and is 305:1(188:1) and 143:1(122:1) for the stratospheric(tropospheric) GW, the former is about 1.62(1.17) times of the latter.
