Response of tropical lower atmosphere to annular solar eclipse of 15 January, 2010
Abstract Special experiments were conducted at the time of annular solar eclipse of 15 January, 2010 from two tropical Indian stations Hyderabad and Gadanki to study changes in the lower atmosphere due to solar obscuration. A significant fall in temperature and ozone concentration has been observed below the tropopause with a rise in the lower stratosphere (18.5–20 km). Measurements show an increase in zonal wind velocity during eclipse. Meridional winds do not show appreciable changes. Very high frequency gravity waves close to Brunt Vaisala period are observed to be generated by the eclipse in the upper troposphere and lower stratosphere, which could be partially responsible for the reorganization of atmospheric species.
