We replace the existing land surface parameterization scheme, the Biosphere-Atmosphere Transfer Scheme (BATS), in a regional climate model (RegCM) with the newly developed Common Land Model (CLM0). The main improvements of CLM0 include a detailed 10-layer soil model, the distinction between soil ice and water phases, a linked photosynthesis-stomatal conductance model, a multilayer snow model, a...

The efficacy of two latest versions regional climate models (RegCM and WRF) for simulating the Indian summer monsoon (JJAS) is tested in this study. CFSv2 hindcast outputs are downscaled over domain 11 contrasting seasons using models. April start ensembles averaged to generate initial lateral boundary conditions driving WRF RegCM. perform better features than parent model. rainfall pattern as ...

We apply a hierarchy of atmospheric and process models to assess the response in Western North America to a canonical North Atlantic Heinrich event that is characterized by lowering of the Laurentide Ice Sheet (LIS) and subsequent warming of North Atlantic sea surface temperatures (SSTs). Global responses to changes in the LIS and SSTs are simulated by the GENESIS general circulation model. Lat...

The marine surface wind field (10 m) over the Greek seas is analyzed in this study using The RegCM. The model’s spatial resolution is dynamically downscaled to 10 km × 10 km, in order to simulate more efficiently the complex coastlines and the numerous islands of Greece. Wind data for the 1980–2000 and 2080–2100 periods are produced and evaluated against real observational data from 15 island a...

Abstract. In this study, a new regional Earth system model is developed and applied to the Med-CORDEX (Coordinated Regional Climate Downscaling Experiment) region. The ENEA-REG made up of two interchangeable climate models as atmospheric components (RegCM, REGional Model, WRF, Weather Research Forecasting), river (Hydrological Discharge, HD), an ocean (Massachusetts Institute Technology General...

Though, according even to the most pessimistic forecasts, Hungary is expected to remain amongst the regions with good quality grapevine growing conditions in the future, the expected frequency and the impact of extreme climatic events are rather serious warning signs. In this study first some impactful climatic indicators are analyzed which are of high importance in grapevine production. Histor...

The global water cycle is becoming more intense in a warming climate, leading to extreme rainstorms and floods. In addition, the delicate balance of precipitation, evapotranspiration, runoff affects variations soil moisture, which vital importance agriculture. A systematic examination climate change impacts on these variables may help provide scientific foundations for design relevant adaptatio...

In the purview of global warming, the present study attempts to project changes in climate and quantify the changes in aridity of two coastal districts in south India under the RCP 4.5 trajectory. Projected climate change output generated by RegCM 4.4 model, pertaining to 14 grid points located within the study area, was analyzed and processed for this purpose. The meteorological parameters tem...
