Abstract

This study statistical approach - analytical, with the aim of analyzing change was spatiotemporal height of the boundary layer (BLH) were the order of the height of the boundary layer of the European Centre for Medium-Range Weather Forecasts (ECMWF) version of the ERA-Interim with spatial resolution 0/125 ° × 0/125 ° arc period 1979 to 2015 were used. The results showed that the pace of change when boarding height of the boundary layer influenced by the pace of change and seasonal temperature pattern on the one hand and the components of latitude and altitude is. When the maximum height of the boundary layer in June and a minimum height of boundary layer occurs in January. The furnishing and rugged Zagros highlands and desert areas Sawwah has a minimum thickness of the boundary layer and smooth inner regions, especially South-East and Central regions of Iran, the thickness of the boundary layer is at the highest level. Changes in the boundary layer height space in the cold months is more consistent warmer months. Adjacent coastal areas and the sea because the sea moderating role in the temperature always have the minimum thickness of the boundary layer. In the cold months the maximum height of the boundary layer in the southern part of East and especially during the hot months of June and July in the western region and northern and southern Kerman province to be drawn.
