The Negative and Positive Divergence of the Heat and the Rain Refraction from their Common Average at Mosul, Baghdad and Basra Stations

Abstract

Understanding of weather phenomena reached the point that many nations of the world deemed it to be in the public interest to establish weather services charged with the task of providing forecasts of changing weather conditions and timely warnings of weather events that might pose risks to life and property . The present study used the concept of deviation in temperature averages and rainfall for longest possible period provided by metorological records for three stations in Iraq “ Mosel , Baghdad and Basrah . All stations showes clear deviations from the overall averages for temperatures and rainfall .Most deviations were positive with the first element , which means temperature increasing with time . Negative deviations associated with rainfall , which means rainfall decreasing with time .Basrah showes highest increasing temperature ,followed by Mosel , then Northern hemisphere and Baghdad at last . Analyzing rain data showes that Baghdad recorded the biggest diminution ,then Mosel and Basrah .
