Meteorological field ovservations were conducted at an irrigated alfalfa farm in arid area to evaluate the mitigation caused by the farm effect against the intense heat in summer. Atmospheric on the farm was always in stable conditions. The atmospheric temperature decreased 5 degs. from the upwind edge of the farm to its downwind edge. These phenomena were well reproduced by the turblent closure model. Evapotranspiration from the farm was estimeted to be 11mm/day, which was reasonable value in comparison with other estimated value in arid area.
