Abstract:
يهدف البحث الى دراسة تكرار الظواهر الجوية الغيوم، والعواصف الرعدية، والبرق، والبرد وعلاقة بعضها ببعض في العراق للمدة من 1991 - 2002 م في جهات القطر المختلفة وتحليل العوامل التي تقرر حدوثها وتوزيعها الجغرافي وعلاقة بعضها ببعض من اجل اعطاء صورة حقيقية عن طب | This study aims at studying the recurrence of atmospheric phenomena like clouds, thunder storms, lightning and hails, and their relation with each other. In Iraq between 19991 - 2002 in different areas of the country it also aims at analyzing the factors that decide their occurrence together with their geographic distribution and their relation with each other to give a realistic image of the nature of atmospheric phenomena in addition to specifying the time and places in which they occur during the and place distinction. This is due to the fact that these phenomena have positive and negative impacts on different sides of life. his study falls into four chapters with different sections. First chapter deals with studying the influential factors in atmospheric phenomena (clouds, thunder storms and the phenomena of lightning and hails) represented by the solar radiation, temperature, humidity, winds, jet currents, air masses, and low atmosphere. Chapter two deals with studying the atmospheric phenomena recurrence (clouds, thunder, storms, and the phenomena of lightning and hails). This chapter consists of four sections : Section one deals with studying clouds : the factors responsible foe low, mid and high duds formation , their types and geographic distribution. Section two deals with studying thunder storms, outspread weather that accomplices rainy and non - rainy thunder storms, and their geographical destruction. Section three deals with studying lighting phenomena, lighting formation , types of lightning and their geographic distribution. Section four deals with studying hail phenomena, hail formation and their geographic distribution. Chapter three consists of three section : Section one deals with studying the relationship between low clouds and rainy and non - rainy thunder storms and the phenomena of lightning and hails. Section two deals with studying the relationship between mid, clouds and rainy and non - rainy thunder storms, and the phenomena of lightning and hails. Section three deals with studying the relationship between high - clouds and rainy and non - rainy thunder storms , and the phenomena of lightning and hails. Section four deals with studying the relationship between clouds rising and rainy non - rainy thunder storms, and the phenomena of lighting and hails. During this study of the recurrence of atmospheric phenomena (clouds, thunder storms, and the phenomena of lightning and hails) in Iraq , many facts are revealed and summarized as : 1 - Multiplicity of factors responsible for the formation atmospheric phenomena (clouds, thunder, storms, lighting and hails). 2 - There is time place conflict for clouds , thunder storms, lighting and hails among areas included in this study
