The potential of aridity of Great Indian Desert in the atmospheric circulation: A numerical simulation study
An assortment of predominant physiographic features: arid and semiarid Great Indian Desert (GID) in the northwest, snow covered Himalayas in the north and evergreen tropical forests of Karnataka and Kerala in the south of India nestle in Indian monsoon region. In an attempt to understand the role of aridity of GID, two seasonal simulations of atmospheric circulations during June, July and August 1987 had been made with LMD Atmospheric General Circulation Model using two classified vegetation global covers. They distinguished in the vegetation merely over GID replaced with the type of Amazonian forest. The initial atmospheric state and terrestrial surface conditions prepared from ECMWF observed analyses for June 1, 1987 were used. In addition, the sea surface temperatures were prescribed from the data set of Reynolds and Roberts (USA). To stress upon the evapotranspiratory character of the imposed forest over GID, the fields of albedo and surface roughness were taken independent of afforestation. The resultant mean monthly fields of velocity potential and wind vector at 200 mb and 850 mb and precipitation had been analyzed for their anomalies. This simulative study of an imposed analogy of Amazonian forest evapotranspiration (ET) over GID exhibits its pronounced effects on the lower and upper atmospheric circulations.
