摘要: A state-of-art regional climate modelling system, known as PRECIS (Providing REgional Climates for Impact Studies) and MRI-JMA (Meteorological Research Institute - Japan Meteorological Agency) AGCM (Atmospheric General Circulation Model) is applied to develop high-resolution change scenarios Northwest (NW) India winter season. The present-day simulation (1961-1990) with (1990s) evaluated. models are able resolve features on finer scales than those resolved by the GCM, particularly related improved resolution of topography. simulations under increasing greenhouse gas concentrations sulphate aerosols indicate marked increase in both precipitation surface temperature towards end 21st century.
