Abstract This study is the first that worked on temporal and spatial distributions of annual rainfall (Pyear) maximum 24-h (Pmax24h) in Semnan province. For this purpose, different statistical were used to estimate Pyear Pmax24h Six synoptic stations across province studied all had complete data. Different return periods studied. The goodness fit test for showed about 67% follow Generalized Par...

The katabatic wind system over the Greenland ice sheet is studied using simulations of the hydrostatic Norwegian Limited Area Model (NORLAM) and measurements of an instrumented aircraft. The structure and the dynamics of the katabatic wind over the ice sheet are investigated for a case study of the aircraft-based experiment KABEG (Katabatic wind and boundary layer front experiment around Greenl...

Mesoscale air quality under stagnant synoptic cold season conditions in the Lake Powell area is characterized through climatological, topographical and numerical studies. Using a synoptic climatological classification scheme, it is found that during the winter this region is dominated by stagnant conditions associated with slow-moving high pressure systems. Using topographic analyses, the Lake ...
