“…The wind speed continued to decrease for two hours after the eclipse event without any significant change in direction. Kolev et al (2005) observed similar changes in the wind speed in Bulgaria during the solar eclipse of 11 August 1999. The temporal variation of the above mentioned meteorological parameters during the solar eclipse of 29 March, 2006 is in close agreement with observations at three other stations (Thission, Penteli, Markopoulo) in the Athens basin reported by Founda et al (2007).…”

“…The experimental data obtained from different observational sites in Bulgaria during the solar eclipse of 11 August 1999, demonstrated that the influence of the phenomenon was manifested with a certain delay and the duration of the impact of the eclipse on the ground ozone concentration was almost two hours (Kolev et al, 2005).…”

“…However, the number of studies exploring the effects of solar eclipse on surface temperature and surface winds as well as on surface ozone (SOZ) and its precursors is relatively small (Srivastava et al, 1982;Fernadez et al, 1993;Zerefos et al, 2001;Kolev et al, 2005;Tzanis, 2005.…”

Abstract. In this study the variations in the surface ozone concentration, the solar ultraviolet radiation and the meteorological parameters at the ground before, during and after the total solar eclipse of 29 March 2006 have been examined. This analysis is based on the measurements performed at four stations located in the greater Athens basin in Greece. The experimental data demonstrated that the solar eclipse phenomenon affects the surface ozone concentration as well as the temperature, the relative humidity and the wind speed near the ground. The decrease in the surface ozone concentration that observed after the beginning of the eclipse event lasted almost two hours, probably due to the decreased efficiency of the photochemical ozone formation. The reduction of the solar ultraviolet radiation at 312 and 365 nm reached 97% and 93% respectively, while the air temperature dropped, the relative humidity increased and the wind speed decreased.

“…The sky was clear throughout the event, and hence, the eclipse maximum from 13:24 to 13:29, gave a dark effect of decrease in light intensity. Kolev et al [19] observed a continuous decrease in wind speed without any significant change in direction during the solar eclipse of 11 August 1999. Founda et al [20] also reported a similar effect of observations during the solar eclipse 29 March 2006.…”

Eclipse induced changes in solar radiation is a common interest of scientists all over the world. The disturbance of the heat balance along the supersonic travel of the trajectory of the Moon's shadow could generate gravity waves during solar eclipse, which results a reduction in the concentration of ozone layer in the stratosphere. We, in this context, conducted some experiments to detect the possible radiations reaching the surface of the earth and the impact of such radiation in seawater during the recent total and annular solar eclipses. This is the first time that the variation in pH value of seawater during solar eclipse is examined, and the experimental data demonstrated that the solar eclipse phenomenon affects the pH value of seawater due to the shorter wavelength radiations received on the surface of the earth. The reduction is around 20% and 40% of the difference between ordinary water and seawater during total and annular eclipses respectively. The multidisciplinary influences of these findings are addressed.

“…One of the main observed effects is on the formation and the evolution of the Planetary Boundary Layer (PBL) during the solar eclipse. An aerosol backscatter lidar was used by Kolev et al [1] to investigate the dynamics of the PBL during the solar eclipse of 11 August 1999, over Bulgaria. This study demonstrated that the solar eclipse affects the meteorological parameters of the atmosphere near the ground, the ozone concentration and the height of the mixing layer.…”
