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

Abstract

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