A Study of Gravity Wave Characteristics at High Frequencies

Atmospheric dynamics rely heavily on gravity waves (GWs) because of their effects on turbulence formation, energy and momentum transmission, and the thermal structure of the middle atmosphere as a whole. Using data from COSMIC GPS RO satellites and high-resolution radiosonde measurements, this research examines the properties of high-frequency gravity waves. This research finds major vertical wavelengths and their seasonal changes by analysing wind and temperature fluctuations throughout various seasons and altitudes. The findings show that there are consistent patterns of propagation for high-frequency GWs with vertical wavelengths in the troposphere ranging from 6-12 km and in the lower stratosphere from 3-7 km. In the troposphere, horizontal wavelengths are 100–300 km, and in the lower stratosphere, they may reach 500 km. Additionally, convection is seen as a possible driving element when looking at these waves from a global viewpoint. Improved atmospheric modelling and climate projections are aided by the study's results, which add to a better understanding of GW dynamics.
