Statistical Study for Free Evaporation at Mosul Area by Kernel Estimation Method

AbstractMeteorological phenomena like temperature, humidity, radiation, wind speed play an important role in the determining the quantity of evaporation. In this study one of the advanced methods in the statistical analysis by computer has been applied to find relation between the present and antecedent evaporation and other meteorological phenomena. Monthly historical data for each phenomenas are collected for the period (1980-2000). The kernel estimation, according to the established computer programs , gives an estimator which depends on the time and nature of the variable .Key words : free evaporation , Mosul area , kernel estimation, statistical study for evaporation.
