  The purpose of this study is assessing the spring precipitation and outgoing long wave radiation using Reviews Climate maps at different levels of the atmosphere, surface and Earth mapping reflecting long-wavelength radiation. For these data synoptic stations of the North West (15 April 2016) was obtained from the meteorological. The data from the induction by NCEP-resolution grid of horizontal 5 degrees of length and width of geographic and through the application Grads, maps of sea level, the 500 hpa daily, Vorticity 700 hpa, map convergence and divergence flow of moisture , long wavelength reflectance map of the earth's surface, atmosphere and map omega vertical advection map queries. Reviews maps indicate that the main cause of precipitation North West of Iran on 26 April, entry system, the rainfall from Eastern Europe and accompanying Western air mass with this system, and the effect of convection locally in the morning because of high levels of outgoing long wave earth is very minimal, but in the afternoon the existence of the local convection has intensified and the highest precipitation occurred in the study Manuscript profile
