RISDiagnosing Land–Atmosphere Interaction from a Regional Climate Model Simulation over West Africa
Publisher: American Meteorological Society
Abstract: Land?atmosphere interaction at climatological time scales in a large area that includes the West African Sahel has been explicitly explored in a regional climate model (RegCM) simulation using a range of diagnostics. First, ...
A New Methodology for Assimilation of Initial Soil Moisture Fields in Weather Prediction Models Using Meteosat and NOAA Data
Publisher: American Meteorological Society
Abstract: In this study, a simple method is described and tested for deriving initial soil moisture fields for numerical weather prediction purposes using satellite imagery. Recently, an algorithm was developed to determine surface ...
Optimized Surface Radiation Fields Derived from Meteosat Imagery and a Regional Atmospheric Model
Publisher: American Meteorological Society
Abstract: High-quality fields of surface radiation fluxes are required for the development of Land Data Assimilation Systems. A fast offline integration scheme was developed to modify NWP model cloud fields based on Meteosat visible ...
Modeled Contrast in the Response of the Surface Energy Balance to Heat Waves for Forest and Grassland
Publisher: American Meteorological Society
Abstract: bservations have shown that differences in surface energy fluxes over grasslands and forests are amplified during heat waves. The role of land?atmosphere feedbacks in this process is still uncertain. In this study, a ...
Contribution of Dynamic Vegetation Phenology to Decadal Climate Predictability
Publisher: American Meteorological Society
Abstract: n this study, the impact of coupling and initializing the leaf area index from the dynamic vegetation model Lund?Potsdam?Jena General Ecosystem Simulator (LPJ-GUESS) is analyzed on skill of decadal predictions in the fully ...
