RISAssimilation of MODIS Cloud Optical Depths in the ECMWF Model
Publisher: American Meteorological Society
Abstract: At the European Centre for Medium-Range Weather Forecasts (ECMWF), a large effort has recently been devoted to define and implement moist physics schemes for variational assimilation of rain- and cloud-affected brightness ...
Improved Middle Atmosphere Climate and Forecasts in the ECMWF Model through a Nonorographic Gravity Wave Drag Parameterization
Publisher: American Meteorological Society
Abstract: In model cycle 35r3 (Cy35r3) of the ECMWF Integrated Forecast System (IFS), the momentum deposition from small-scale nonorographic gravity waves is parameterized by the Scinocca scheme, which uses hydrostatic nonrotational ...
Simplified and Regular Physical Parameterizations for Incremental Four-Dimensional Variational Assimilation
Publisher: American Meteorological Society
Abstract: A set of physical parameterizations has been developed for inclusion in incremental four-dimensional variational assimilation (4D-Var). The goal for this physical package is that it be simple, regular (for the efficiency ...
Assimilation and Modeling of the Atmospheric Hydrological Cycle in the ECMWF Forecasting System
Publisher: American Meteorological Society
Abstract: Several new types of satellite instrument will provide improved measurements of Earth's hydrological cycle and the humidity of the atmosphere. In an effort to make the best possible use of these data, the modeling and ...
