Solar Eclipse Effects on the Air Layer near the Surface over Makkah Region

Abstract. Meteorological measurements were made before, duringand after the Shaaban 29th, 1426H [October 3rd, 2005] partial (60%)solar eclipse over the Hada Al-Sham area, Makkah, Saudi Arabia.From the available data radiative changes were found clearly (depletion)due to the solar eclipse and other meteorological parameterssuch as temperature and humidity. It was a marked change in humiditywith relative humidity increasing 10% and temperature falling 1ºC,27 min after partiality. The energy balance components were computedto determine how the surface layer responded to changes in theground heat flux and other components.
