Abstract:

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 λz, horizontal wavelength λh, vertical group velocity cgz, and horizontal group velocity cgh 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 cgh/cgz and λh/λz because of the background wind. The value of λh/λz and cgh/cgz is 305:1 (188:1) and 143:1 (122:1) for the stratospheric (tropospheric) GW.

Key words: Quasi-monochromatic inertia gravity waves, Intrinsic period, Propagation direction, Meteorological rocket
