“…It also provides a unique opportunity for meteorologists to study the response of the atmosphere or biosphere to the sudden turn off/turn on of the incidental solar radiation during and after the solar eclipse. There are a number of studies and observations made during the solar eclipses (Nymphas et al, 2009, and references therein) which include observations of meteorological parameters, such as wind speed and direction, air temperature, atmospheric pressure, humidity (Anderson et al, 1972;Szalowski, 2002;Dolas et al, 2002;Krishnan et al, 2004;Nymphas et al, 2009), gravity waves (Chimonas and Hines, 1971;Singh et al, 1989;Zerefos et al, 2007), ozone measurements (Chakrabarty et al, 1997;Zerefos et al, 2000;Tzanis et al, 2008) and heat and momentum fluxes within the boundary layer (Krishnan et al, 2004). The impact of a solar eclipse on atmospheric and surface temperature has been widely reported in the literatures (Kolarz et al, Published by Copernicus Publications on behalf of the European Geosciences Union.…”

Abstract. Measurements of atmospheric temperature profiles in the troposphere and lower stratosphere were made over Thumba Equatorial Rocket Launching Station (TERLS) (8.5 • N, 76.9 • E) during a partial solar eclipse (22 July 2009) and an annular solar eclipse (15 January 2010). It was observed that during the partial solar eclipse, the temperature decreased by 2-3 • C in the vicinity of the tropopause and in the lower stratosphere the temperature increased by ∼2.6 • C during the maximum phase of the partial solar eclipse. During the annular solar eclipse, a temperature reduction of ∼2 • C was observed around the tropopause. This study also revealed a feature of delayed effect in the form of a very intense warming of ∼8 • C at 18 km after about 4 h of the annular solar eclipse. The Cold-Point Tropopause (CPT) temperature increased slowly before the beginning of the eclipse (up to 10:00 IST) and during the maximum phase of the eclipse, the difference in CPT temperature and height was −3.5 • C and ∼110 m, respectively, as that of the control day. After the four hours of the eclipse, the CPT height had decreased by ∼1.7 km and the CPT temperature increased by ∼4.6 • C. This is for the first time that the diurnal variation of the tropopause has been reported during a solar eclipse day. The present study, thus, provided an opportunity to investigate the temperature perturbations in the troposphere and lower stratosphere during a partial and annular solar eclipse. The highlight of the present results are (1) cooling of the entire troposphere and lower stratosphere during the maximum phase of annular solar eclipse, (2) an intense heating of the lower stratosphere by 8 • C after nearly four hours from the maximum phase of the annular eclipse, and (3) drastic variations in the diurnal evolution of the tropical tropopause characteristics. The cooling effect is attributed to the radiative response of the atmosphere to the solar eclipse, where as heatCorrespondence to: K. V. Subrahmanyam (kvsm2k@gmail.com) ing is attributed to the dynamical response of the atmosphere to the solar eclipse. These results may have important implications in understanding the response of the atmosphere to the radiative, as well as dynamical, perturbations caused by any celestial or terrestrial disturbances.

“…Eaton et al (1997) reported wind bursts before and after the eclipse period. Nymphas et al (2009) reported a decrease in wind speed immediately after the first contact during solar eclipse over Nigeria. In our case, winds started to decelerate only after the peak eclipse over our station and a gradual decrease is observed for a period of 40 min in the lower level winds.…”
