In this work are showed the comparison between the results of wind and temperature simulation and data weather measurements in low layers near Gualeguaychú City, Argentine, for 12 hours on January 1st 2011. We are used the model ARPS (Advanced Regional Prediction System) with two options in the boundary conditions. In a case such conditions were used with wave-radiating open (radiative) with relaxation to the initial state while otherwise used absorbing boundary conditions data forced from Meso-scale Boundary Layer Model (MBLM) operational forecasters used by the National Weather Office. The results of both simulations are compared with data measured by three weather stations located around of the Uruguay River. As both simulations are initialized using the same data, there is a better agreement between the values obtained by forcing the boundary conditions for which are using ?radiative? boundary conditions after 2 hours physic-time from the start of the simulation.
