As Pakistan locates at the transit zone from central to southern Asia, its climate variability is subject to planetary circulation forcings and regional interactions with complex surface characteristics. As such, credible prediction of the regional climate requires realistic representation of land-atmosphere interactions and large-scale monsoonal processes. The state-of-the-art regional Climate-Weather Research and Forecasting (CWRF) model offers a unique tool to better understand the physical processes and ultimately improve the numerical prediction of Pakistan climate, especially precipitation. The CWRF, however, requires accurate specification of comprehensive surface boundary conditions (SBCs) to define regional land-atmosphere interactions and optimal design of the computational domain to correctly integrate the planetary circulation forcings. As the initial but necessary step, this study focuses on [1] Development of an Interactive CWRF Preprocessing System (iCWPS) that enables GIS-based, construction of the essential SBCs for any given horizontal resolution and domain position; and [2] Analysis of Pakistan precipitation teleconnection with planetary circulation patterns that facilitate the optimal domain position for the CWRF to realistically integrate large-scale forcings.
