Numerical Experiment of Cloud and Precipitation Activity around the Tibetan Plateau

Yasunori KUROSAKI (1), Fujio KIMURA (2)

Numerical experiments of precipitation systems are carried out by using a cloud cluster resolving model, focusing on the cloud system over highly elevated and largely undulating topography over the Tibetan Plateau and over the steep slope of southern slope of Himalayas. The numerical model, Regional Atmospheric Modeling System (RAMS), is utilized as two dimensional with 2 km horizontal grid interval. Initial and boundary conditions are given by European Centre for Medium-Range Weather Forecasts (ECMWF) global analysis data. Numerical experiments agree well with the following three major results which has been previously obtained by the analysis of visible and infrared GMS images by the authors: (1) high-level cloud frequently appears over major mountain ridges of the Tibetan plateau but less cloud over major valley regions during late afternoon in premonsoon and monsoon periods, (2) low-level cloud often exists over the plateau during the morning in the monsoon period, and (3) low-level cloud often covers the southern slope of Himalayas.
