دراسة تحليلية للمطبات الهوائية الحرارية فوق مدينة بغداد

Abstract

By using the upper observing for two times 00 and 12 UTC for two months, March and April, for three years recorded at meteorological International Baghdad airport. The location and intensity have determined the thermal air turbulence for two layers such that 0-3 km and 3-6 km. The results show that the number of frequencies of severe and moderate turbulences at the months in the first layer is more than those at 00 UTC. In the second layer frequency of severe turbulence at 12 UTC and 00 UTC are equal. In addition, empirical expressions between thermal turbulences and some thermodynamic parameters such as the difference between air temperature and dew point temperature and the height of convective condensation level have been concluded.
