Potential Predictability of Malaria in Africa Using ECMWF Monthly and Seasonal Climate Forecasts
Publisher: American Meteorological Society
Abstract: dealized model experiments investigate the advance warning for malaria that may be presently possible using temperature and rainfall predictions from state-of-the-art operational monthly and seasonal weather-prediction ...
Generalizing Cloud Overlap Treatment to Include Solar Zenith Angle Effects on Cloud Geometry
Publisher: American Meteorological Society
Abstract: Shortwave radiative transfer depends on the cloud field geometry as viewed from the direction of the sun. To date, the radiation schemes of large-scale models only consider a zenith view of the cloud field, and the apparent ...
An Interpretation of Cloud Overlap Statistics
Publisher: American Meteorological Society
Abstract: bservational studies have shown that the vertical overlap of cloudy layers separated by clear sky can exceed that of the random overlap assumption, suggesting a tendency toward minimum overlap. In addition, the rate of ...
Generalizing Cloud Overlap Treatment to Include the Effect of Wind Shear
Publisher: American Meteorological Society
Abstract: ix months of CloudSat and CALIPSO observations have been divided into over 8 million cloud scenes and collocated with ECMWF wind analyses to identify an empirical relationship between cloud overlap and wind shear for use ...
Leaf Area Index Specification for Use in Mesoscale Weather Prediction Systems
Publisher: American Meteorological Society
Abstract: The energy budget at the surface is strongly influenced by the presence of vegetation, which alters the partitioning of thermal energy between sensible and latent heat fluxes. Despite its relevance, numerical weather ...
Soil Initialization Strategy for Use in Limited-Area Weather Prediction Systems
Publisher: American Meteorological Society
Abstract: hree diverse methods of initializing soil moisture and temperature in limited-area numerical weather prediction models are compared and assessed through the use of nonstandard surface observations to identify the approach ...
Improving Forecasts of Biomass Burning Emissions with the Fire Weather Index
Publisher: American Meteorological Society
Abstract: AbstractIn the absence of a dynamical fire model that could link the emissions to the weather dynamics and the availability of fuel, atmospheric composition models, such as the European Copernicus Atmosphere Monitoring ...
The Potential Predictability of Fire Danger Provided by Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: global fire danger rating system driven by atmospheric model forcing has been developed with the aim of providing early warning information to civil protection authorities. The daily predictions of fire danger conditions ...
