Relationship of Surface Temperature and Average Relative Humidity for Selected Governorates of Iraq ( Baghdad, Al-Mosul and Al-Muthna )

Abstract study and analysis the trends of paths climatic elements (maximum minimum temperatures relative humidity) received great attention evaluated their statistical importance in terms assessing climate changes. In this research, data were taken for maximum temperature humidity several different governorates location, namely (Baghdad, al-Al-Mosul Al-Muthna), Sigma plot program was used to extract forms relationship between average each month selected years study. The time series showed that them is an inverse relationship, as well fluctuations occur values high low months year, but clearly appeared spring autumn seasons, reason these two seasons have transitional characteristics weather, especially temperature. Also, through correlation coefficient extracted all months, its results mostly negative, which are mentioned attached tables, indicate above. been reached observation difference governorates, starting from Mosul with humidity, down Baghdad then Al-Muthna, begins increase a decrease explains geographical location governorate extent impact on temperatures. Temperature, other elements.
