AbstractThis research aims to study the relationship between the surface air temperature and the evapotranspiration In the stations of Kirkuk city (Latitude: 35.47 °N, Longitude: 44.39° E) (Haweija, Alton Copery, Daquq and Qara enger) by using data of (Surface Air Temperature and Evapotranspiration) In (2013), which was obtained from the Iraqi Agro meteorology Network / Ministry of Agriculture.
In this study the relationship between air temperature and values of evapotranspiration has been investigated by calculation the correlation coefficient by using program of Microsoft excel 2010, the results indicated the existence of strong linear correlation between the monthly and seasonally average of air temperature and the monthly and seasonally sum of evapotranspiration In the four studying stations.
Monthly correlation coefficient values between (0.963 – 0.978), while Seasonally correlation coefficient values between (0.80 – 0.99) in studying stations. This indicates that the increasing in surface air temperature leads to increase the values of evapotranspiration, and the decreasing in surface air temperature leads to decrease the values of evapotranspiration
