This research includes the study of the temporal variation and spatial of relative humidity in several locations in Iraq (Mosul, Kirkuk, Baghdad, Rutba and Basra)at these locations the humidity data base was analyzed and studied to find out its relation with different climatic elements. the results indicated the existence of strong linear, proportional and inverse link relations between the relative humidity and different climatic elements. Correlation coefficient values where in the region

There was a rapid fall in relative humidity values in Summer at all other stations. where the range of the relative humidity values was (%23-%28). The relative humidity values in autumn was close to that taken at spring time for all stations. monthly basis of the time series of relative humidity was analyzed at all stations and it showed that the general direction increase slowly with time (in months) at Rutba and Kirkuk stations, while it decrease with time (in months) at Mosul, Baghdad and Basra Stations. ‫اﻟﻣﻠﺧص‬ ‫اق‬ ‫اﻟﻌر‬ ‫ﻣن‬ ‫اﻗﻊ‬ ‫ﻣو‬ ‫ﻋدة‬ ‫ﻓﻲ‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫ﻟﻠرطوﺑﺔ‬ ‫اﻟﻣﻛﺎﻧﻲ‬ ‫و‬ ‫اﻟزﻣﺎﻧﻲ‬ ‫اﻟﺗﺑﺎﯾن‬ ‫اﺳﺔ‬ ‫در‬ ‫اﻟﺑﺣث‬ ‫ﯾﺗﺿﻣن‬ ‫وﻫﻲ‬ ) ‫اﻟﻣوﺻل‬ , ‫ﻛرﻛوك‬ , ‫ﺑﻐداد‬ , ‫اﻟرطﺑﺔ‬ , ‫ة‬ ‫اﻟﺑﺻر‬ .( ‫ﻓ‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫اﻟرطوﺑﺔ‬ ‫ﺑﯾﺎﻧﺎت‬ ‫ﺗﺣﻠﯾل‬ ‫ﺗم‬ ‫ﺣﯾث‬ ‫ﻫذﻩ‬ ‫ﻲ‬ ‫اﻟﻣﺧﺗﻠﻔﺔ‬ ‫اﻟﻣﻧﺎﺧﯾﺔ‬ ‫اﻟﻌﻧﺎﺻر‬ ‫ﻣﻊ‬ ‫اﺑطﻬﺎ‬ ‫ﺗر‬ ‫ﻣدى‬ ‫اﺳﺔ‬ ‫ودر‬ ‫اﻗﻊ‬ ‫اﻟﻣو‬ . ‫ﻋﻼﻗﺎت‬ ‫وﺟود‬ ‫اﻟﻧﺗﺎﺋﺞ‬ ‫أظﻬرت‬ ‫اق‬ ‫اﻟﻌر‬ ‫ﻓﻲ‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫ﻟﻠرطوﺑﺔ‬ ‫اﻟﻣﻛﺎﻧﻲ‬ ‫و‬ ‫اﻟزﻣﺎﻧﻲ‬ ‫اﻟﺗﺑﺎﯾن‬ . 117 ‫اﻟﻣﻧﺎﺧﯾﺔ‬ ‫اﻟﻌﻧﺎﺻر‬ ‫و‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫اﻟرطوﺑﺔ‬ ‫ﺑﯾن‬ ‫ﻗوﯾﺔ‬ ‫وﻋﻛﺳﯾﺔ‬ ‫طردﯾﺔ‬ ‫ﺧطﯾﺔ‬ ‫ﺗﺑﺎط‬ ‫ار‬ ‫اوﺣت‬ ‫ﺗر‬ ‫اذ‬ ‫اﻟﻣﺧﺗﻠﻔﺔ‬ ‫ات‬ ‫اﻟﻣﺗﻐﯾر‬ ‫ﻫذﻩ‬ ‫ﺑﯾن‬ ‫ﺗﺑﺎط‬ ‫اﻻر‬ ‫ﻣﻌﺎﻣل‬ ‫ﻗﯾم‬ ) 0.83 ‫ـ‬ 0.99 ( ‫ﯾ‬ ‫اﻟر‬ ‫ﺳرﻋﺔ‬ ‫ﻣﻊ‬ ‫اﻟﻌﻼﻗﺔ‬ ‫ﺑﺎﺳﺗﺛﻧﺎء‬ ‫اﻟﺗﻲ‬ ‫ﺎح‬ ‫ﺑﯾن‬ ‫ﻓﯾﻬﺎ‬ ‫ﺗﺑﺎط‬ ‫اﻻر‬ ‫ﻣﻌﺎﻣل‬ ‫اوح‬ ‫ﯾﺗر‬ -0.38) ‫اﻟﻰ‬ (-0.77 . ‫ﻓﺻل‬ ‫ﻓﻲ‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫ﻟﻠرطوﺑﺔ‬ ‫اﻟﻘﯾم‬ ‫أﻋﻠﻰ‬ ‫ان‬ ‫ﻓﻲ‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫اﻟرطوﺑﺔ‬ ‫ﻗﯾم‬ ‫ﻓﻲ‬ ‫ﺣﺎد‬ ‫اﻧﺧﻔﺎض‬ ‫ﻫﻧﺎك‬ ‫ان‬ ‫و‬ ‫اﻟﻣوﺻل‬ ‫ﻣﺣطﺔ‬ ‫ﻓﻲ‬ ‫ﻛﺎﻧت‬ ‫ﺑﯾﻊ‬ ‫اﻟر‬ ‫و‬ ‫اﻟﺷﺗﺎء‬ ‫ﺑﯾن‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫اﻟرطوﺑﺔ‬ ‫ﻗﯾم‬ ‫اوﺣت‬ ‫ﺗر‬ ‫اذ‬ ‫اﻟﻣﺣطﺎت‬ ‫ﻟﺟﻣﯾﻊ‬ ‫اﻟﺻﯾف‬ ‫ﻓﺻل‬ ) 23 % ‫ـ‬ 28 (% , ‫ﻓﺻل‬ ‫اﻣﺎ‬ ‫اﻟ‬ ‫ﻛﺎﻓﺔ‬ ‫ﻟﻠﻣﺣطﺎت‬ ‫ﺑﯾﻊ‬ ‫اﻟر‬ ‫ﻓﺻل‬ ‫ﻣﻊ‬ ‫ﺑﺔ‬ ‫ﻣﺗﻘﺎر‬ ‫ﻗﯾم‬ ‫اظﻬر‬ ‫ﻓﻘد‬ ‫ﯾف‬ ‫ﺧر‬ . ‫ﻟﻠﻘﯾم‬ ‫اﻟزﻣﻧﯾﺔ‬ ‫اﻟﺳﻼﺳل‬ ‫ﺗﺣﻠﯾل‬ ‫ﺗم‬ ‫ﺣﯾث‬ ‫ﻛﺎﻓﺔ‬ ‫ﻟﻠﻣﺣطﺎت‬ ‫اﻟﻧﺳﺑﯾﺔ‬ ‫ﻟﻠرطوﺑﺔ‬ ‫ﯾﺔ‬ ‫اﻟﺷﻬر‬ ‫أظﻬرت‬ ‫ﯾﻣﯾل‬ ‫ﻋﺎم‬ ‫اﺗﺟﺎﻩ‬ ‫ﻫﻧﺎك‬ ‫ان‬ ‫اﻟﻣﺣطﺎت‬ ‫ﻫذﻩ‬ ‫إﻟﻰ‬ ‫اﻟزﻣن‬ ‫ﻣﻊ‬ ‫اﻟﺑﺳﯾطﺔ‬ ‫ﯾﺎدة‬ ‫اﻟز‬ ‫ﺑﺎﻷﺷﻬر‬ ‫ﯾﻣﯾل‬ ‫ﺣﯾن‬ ‫ﻓﻲ‬ ‫وﻛرﻛوك‬ ‫اﻟرطﺑﺔ‬ ‫ﻟﻣﺣطﺗﻲ‬ ‫إﻟﻰ‬ ‫ﻣﻊ‬ ‫اﻟﻧﻘﺻﺎن‬ ‫اﻟزﻣ‬ ‫ن‬ ‫ﺑﺎﻷﺷﻬر‬ ‫اﻟﻣوﺻل‬ ‫ﻟﻣﺣطﺎت‬ , ‫ﺑﻐداد‬ , ‫ة‬ ‫اﻟﺑﺻر‬ .
