子午工程首次火箭探空数据准单色惯性重力波特性分析

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（20~50km）和对流层（0~15km）廓线提取了海南火箭发射场上空准单色惯性重力波参数.火箭探测的平流层和对流层两个准单色惯性重力波分别向上和向下逆风传播，固有周期为20.1h和22.4h，垂直波长为9.5km和4.0km，水平波长为2900km和753km，垂直群速度c_gz为0.0887m·^-1和0.0298m·^-1，水平群速度c_gh为12.7m·^-1和3.65m·^-1，λ_h/λ_z为305：1和188：1，c_gh/c_gz为143：1和122：1.

Characteristics of Quasi-monochromatic Inertia Gravity Waves Revealed by First Meteorological Rocket Data of the Meridian Space Weather Monitoring Projectormalsize

Wind and temperature data detected by the first meteorological rocket of the Meridian Space Weather Monitoring Project were used to study quasi-monochromatic inertia Gravity Waves (GW) over Hainan rocket launch site (19.5°N, 109°E). The GW extracted from the stratosphere (troposphere) revealed by rocket sonde data is upward (downward) GW, and propagates against the background wind. The intrinsic period, vertical wavelength λ_z, horizontal wavelength λ_h, vertical group velocity c_gz, and horizontal group velocity c_gh of Stratospheric (Tropospheric) GW are 20.1h (22.4h), 9.5km (4km), 2900km (753km), 0.0887 (0.0298)m·-1, and 12.7 (3.65)m·-1, respectively. There is a significant difference between c_gh/c_gz and λ_h/λ_z because of the background wind. The value of λ_h/λ_z and c_gh/c_gz is 305:1 (188:1) and 143:1 (122:1) for the stratospheric (tropospheric) GW.
