Abstract

A Studies in recent years have paid attention to the climate at the local and global levels, describing the climate as an important natural resource, and it is employed in the service of various development plans. The research aims to study the dust phenomena in the Iraqi Jazeera region, depending on the climatic readings of the climatic stations used for the study and for the period (1980-2014) taken from the General Authority for Meteorology and Seismic Monitoring in Baghdad, as well as the sources, books, statistical programs and geographic information systems programs. In order to achieve the objective of the study, we must address the conduct of statistical analyzes of a number of climatic elements in the study area, and to achieve the objective of the thesis, we must address the knowledge of the climatic characteristics of the study area, which vary from one station to another, so the solar brightness varies temporally and spatially, so the summer months recorded the highest rates and the highest (12.5) hours/day during June. As for the annual rates of solar brightness, there is no significant discrepancy between the stations of the study area, but the modern station remains in the first place with the highest rate (8.8) hours/day. As for the temperatures, a clear discrepancy appears, so it is the month of January. The second of the coldest months, as Mosul and Sinjar stations recorded (7.0) C. July recorded the highest rates (36.0) C in Baiji station, as well as The wind speed varies from one station to another, spatially and temporally. Therefore, the Tal Afar station recorded the highest wind speed at a rate of (5.2) m/s in July, and the station itself recorded the lowest rate (3.5) m/s in November. The amount of rain varies in terms of its temporal distribution. And spatial, as the amount of precipitation increases in the winter and spring seasons, so Sinjar station recorded the highest amount of precipitation with an annual total of (361.3) mm, and Ramadi recorded the lowest annual total B (105.5) mm. The highest value amounted to (607.9) mm, and after identifying the most important climatic characteristics in the study area and their variations, conducting a spatial correlation between these characteristics and dust phenomena, and building a spatial model for dust phenomena. It turned out that the highest correlation coefficient was with wind speed and dust storms, as indicated by the value of the correlation coefficient, which appeared equal to (0.250), and this relationship was significant based on the probability value, which appeared equal to (0.032), which is less than (0.05). That is, when the wind speed increases Dust storms are active, and there is a direct and significant correlation between rising dust and evaporation, in terms of the value of the correlation coefficient, which appeared equal to (0.585), and this relationship is significant based on the probability value, which appeared equal to (0.032), which is less than (0.05). The higher the evaporation, the higher the chances of rising dust. There is an inverse correlation, but it is not significant, between suspended dust and rain, in terms of the value of the correlation coefficient, which appeared equal to (0.077), and this relationship is not significant based on the probability value, which appeared equal to (0.207), which is less than (0.05). Through the application of spatial modeling of dust phenomena in the study area, the results showed that the highly developed areas of dust storms had an area of (191144.11) km 2 by (30.88)%, while the less developed areas occupied the least area (13099.39) km 2 with a rate of (21.10)% of the study area. While the rising dust was the highest percentage for the medium-origin regions, as it occupied an area of (36835.43) square kilometers, at a rate of (59.43)% of the study area. Concerning the phenomenon of suspended dust, the highly developed areas occupy the first rank in terms of area (29679.36) km2 with a rate of (47.88)% of the study area, while the excluded areas occupy the last rank in terms of area (149.50) km2 with a rate of (0.31%). ### file The Republic of Iraq.pdf PAGES=2 --- page 1 [OCR+] --- The Republic of Iraq Ministry of Higher Education and Scientific Research University of Mosul College of Education for Humanities Department of Geography Dust phenomena in the Iraqi Jazeera region Mana'a Najah Muhammad Al shamrokhi A Master Thesis Geography / Natural Geography Supervised by Dr. Surah Bader Hussein AL Najmawi 1444 A.H 2022 A.D [OCR of page] The Republic of lraq Ministry of Higher Education and | | Scientific Research University of Mosul = College of Education for Humanities Department of Geography Dust phenomena in the Iraqi Jazeera region Mana‘'a Najah Muhammad Al shamrokhi A Master Thesis Geography / Natural Geography Supervised by Dr. Surah Bader Hussein AL Najmawi 1444 A.H 2022 A.D --- page 2 [OCR+] --- Dust phenomena in the Iraqi Jazeera region A thesis submitted To The Council of the College of Education For Humanities University of Mosul As a partial fulfilment of the requirements for the Master Degree in Humanities / Natural Geography By Manaa Najah Muhammad Sarhan Supervised BY Dr. Surah Bader Hussein AL Najmawi 1444 A.H 2022 A.D [OCR of page] Dust phenomena in the Iraqi Jazeera region A thesis submitted To The Council of the College of Education For Humanities University of Mosul As a partial fulfilment of the requirements for the Master Degree in Humanities / Natural Geography By Manaa Najah Muhammad Sarhan Supervised BY Dr. Surah Bader Hussein AL Najmawi 1444 A.H 2022 A.D ### file إقرار المشرف.pdf PAGES=2
