The Statistical Characteristics of Gravity Waves over Wuhan

摘要

By analyzing the routine radiosonde data obtained at Wuhan (30.5° N, 114° E) from 2000 to 2004, the characteristics of inertial gravity waves in troposphere and lower stratosphere(TLS) were studied, and a strong correlation between the variation of gravity wave energy and jet intensity was found. Similar result of Wuhan was obtained by analyzing the routine radiosonde data obtained at Haikou (20°N, 114'E) and Beijing (40°N, 116°E) Small scale gravity waves with wavelength less than 1 km were extracted from temperature data to give a further discussion on vairation of gravity wave energy at different heights and latitudes.
