Abstract:
This study addressed "The Impact of Frost on the Productivity of Some Winter Yields in Iraq". It aims at identifying the spatial and time variance of frost states, the synoptic conditions, atmospheric characteristics which lead to the occurrence of frost and themanifestation of the impact of frost waves on the physiology, shape and variance of agricultural crop productivity in Iraq for the period 1980 - 2010. it also aims at identifying the protection styles from frost and means of annihilation.To achieve these goals, various data were used some of them concern the atmospheric data of 11 climatic station distributed allover Iraq the northern, eastern, western, middle and southern, some concern the daily weather maps, and some others concern theagrarian data on the frost disadvantages on the agricultural harvests and the area and production of agricultural crops since 1980 - 2010. A number of statistical methods and styles were applied on these data like : The most prominent results at which the study arrived were that the frost types prevailing in Iraq was the radiation frost, most frost states were accompanied by the presence of Siberian anticyclone, the northern and mountain stations (Salahuddin, Sulaimaniya, Mosul) specially were considered the most areas in Iraq witnessing frequent frost waves then followed Aana station in western Iraq, the frequent frost waves on Iraq had a clear negative impact on the agrarian crops in Iraq especially the frost wave of 2008 where the rate of damages were high on various yields, the productivity of agrarian yields were variant in terms of the frequency rage of frost occurrence, its time distribution and the intensity of temperature decrease; therefore, the frost had an evident impact on the most important life areas like agriculture and caused great financial losses which affected different social and economic life fields.Thus, understanding the frost phenomenon and its results enabled us from lowering those losses which affected the national economy.
