Abstract:
The climatic features are only a group of exchangeable relations between the elements that shape them. This study is carried out to seek for the features and traits of the terrain regions of the peninsula, represented by the upper and lower islands, and the western plateau represented by the upper valleys, the rocks and the pattering.The researcher relied in this study on the stations of the terrain regions constructing the area under study. This includes Al - Mousil and sinjar's stations, representing the upper islands' region, Baji's station representing the lower islands' region Al - Rutbah station representing the upper valley's region. Al - Ruwayshid station representing the Hamadah region, and the stations of Anah, Hadithah and Al - Najaf are representing the region of the lower valleys. As for the stations of Al - Nikhaib and Al - Salman, those represent the rocks' region, and for the station of Al - Bassiyah and Al - Theebah, they represent the plattering region.It has been clarified through this study that these region are characterized by a diversity in their topography and in their natural phenomena, and this led to the variations happening in the climatic features of each in the area under study. This has been made obvious by shedding the light on the analysis of the climatic elements (normal temperature, the macro temperature, the micro temperature, wind speed, the relative humidity and rain) of the stations consisting the area under study. Through two study it has also been identified the type of the climate in each of these terrain's regions and this is done by using the climatic classifications as Borisor's classification of identifying thecontinental temperature, Curner's equation of identifying the ocean temperature, Tom's equation of knowing the rate of the climatic comfort for each season (winter, spring, summer and autumn), Lang's criterion to identify the dry region, and finally cobin's classification. The variation coefficient has been used to know the ranging of the climatic elements from one year to another, and to know, also, the climatic characteristics of the regions consisting the area under study.The statistical relation have been used between the surface layers of the area under study, and the climatic elements by using the T - test and correlation coefficient through finding the relations between the light of the stations related the regions of the area under study and their climatic elements.It has also been shown through this study that the high - temperature regions, of the area under study, take the shape of parallel ranges. In this way, Al - Hamada region and the pattering region appeared within a single temperature class, while the regions of the upper islands and the lower islands and of the upper valleys have shown themselves within two different temperature classes. As for the regions of the lower valleys and the rocks, they appeared within three temperature classes. It has also been clarified that the pattering region recorded the highest averages of the macro temperature amongst all the regions consisting the area under study, while the region of the upper islands recorded the lowest ones. Concerning the micro temperature, Al - ltamadah region and the pattering region were both occurring within a single temperature class, while the region of the rocks and the upper valleys were includedwithin two temperature classes, while the other regions, that are the upper islands, the lower islands and the lower valleys, were found within three temperature classes.Fur the more, it has been made obvious through this study that the regions of pattering and of the rocks are the most terrain regions having high wind speed, while the least regions in their wind speed are of Al - Hamadah, of the lower islands and of the upper valleys. Also, it has been clarified that Al - Mousil station is the only one in the area under study that has a normal average of the relative humidity, while in the other stations the relative humidity is absent; these stations proved to be dry. Further, for the amount of the annual falling rains, it decreases as much as the direction is for the north, moving away from the south of the area under study.Also, it is shown in two studies that the area is characterized by a continental climate and this is due to its being for away from the bodies of water, adding to this, is the diversity (variation) in the temperature averages between winter and summer in the area under study. Also, the ocean temperature increases in the north and the western parts of the area and decreases in its other parts. It has been made obvious that the climatic comfort in the area under study is ideal in the two seasons of spring and autumn, while in winter and summer there is no climatic comfort. Also, it is clarified that the stations of Al - Mousil and sinjar are characterized by a dry climate while the other stations have an excessively dry climate according to Lang's classification. Also , the terrainregions in two area are identified as dry regions according to cobia's classification.According to this study, it has been shown that the variation coefficient varies between one region and another in respect to the wind speed and rain amount, while this same coefficient does not show that diversity between one region and another in respect to the other climatic elements (as the normal temperature, macro temperature , micro temperature and relative humidity). It is also clarified that the correlative relation (person's) between the height of the stations above the sea level, and the climatic elements in the area under study (as the normal temperature, macro temperature, wind speed, relative humidity and rain) is an inverse relation except for the rain amount for it is a direct relation, yet it is a weak direct relation. As for the relation of the height of the terrain regions above the sea level with the climatic element, it is an inverse relation, but it ranges from strony, medium to weak.
