چکیده
This paper reviews the cumulative effect of land-cover change on local, regional, and global weather and climate. Documented land-cover changes from 1700 to the present are shown to be particularly significant in the tropics. Model results are presented which show the teleconnection of weather patterns worldwide result from these landscape changes.

Sensitivity Analysis of Different Convection Schemes and Center Domains for Numerical Simulation of Winter Precipitation Over Iran
This paper qualifies the effect of different convection schemes and center-domains on the simulation of winter precipitation over Iran using RegCM3 numerical climate model. It is compressible, finite difference with hydrostatic equilibrium in sigma coordinate with a semi-implicit algorithm for reduction of horizontal diffusion. Iran experienced two dry and wet periods during winters of 1997 and...
متن کاملAssessment of the Regional Climate Model Version 3 over the Maritime Continent Using Different Cumulus Parameterization and Land Surface Schemes
This paper describes an assessment of the Regional Climate Model, version 3 (RegCM3), coupled to two land surface schemes: the Biosphere–Atmosphere Transfer System, version 1e (BATS1e), and the Integrated Biosphere Simulator (IBIS). The model’s performance in simulating precipitation over the Maritime Continent was evaluated against the 3-hourly Tropical Rainfall Measuring Mission (TRMM) Multis...
متن کاملImproving the Simulation of the West African Monsoon Using the MIT Regional Climate Model
This paper presents an evaluation of the performance of the Massachusetts Institute of Technology (MIT) regional climate model (MRCM) in simulating the West African monsoon. The MRCM is built on the Regional ClimateModel, version 3 (RegCM3), but with several improvements, including coupling of Integrated Biosphere Simulator (IBIS) land surface scheme, a new surface albedo assignment method, new...
متن کاملDiurnal Variations in the Community Climate System Model
Diurnal (or sub-daily) variations are large in many surface and atmospheric fields such as solar radiation, surface latent and sensible heat fluxes, surface temperature and winds, atmospheric convection, and precipitation. These diurnal variations are especially important in air-land and air-sea interactions, which are highly non-linear and thus can not be resolved using daily mean values. Curr...
متن کاملThe Development of Regional Climate Change Scenarios for Sub- Saharan Africa
Africa is one of the regions most vulnerable to climate change, is likely the most under-resourced continent for climate change research, and is a region where some aspects of the regional climate dynamics are still poorly understood. This project addresses these needs, primarily through the development of downscaled regional scenarios of climate change from GCM simulations. Analyses of observa...
