RISA Simple Cloud Parameterization Derived from Cloud Resolving Model Data: Diagnostic and Prognostic Applications
Publisher: American Meteorological Society
Abstract: A simple statistical parameterization of cloud water?related variables that has been originally developed for nonprecipitating boundary layer clouds is extended for all cloud types including deep precipitating convection. ...
Effect of Turbulence Parameterization on Assessment of Cloud Organization
Publisher: American Meteorological Society
Abstract: his study evaluates the cloud and rain cell organization in space and time as forecasted by a cloud-resolving model. The forecast fields, mainly describing mesoscale convective complexes and cold fronts, were utilized to ...
Verification of Cloud Cover Forecast with Satellite Observation over West Africa
Publisher: American Meteorological Society
Abstract: The 3-hourly brightness temperatures (BTs) at 10.8 ?m from the Meteosat Second Generation (MSG) satellite were used to document the cloud system variability over West Africa in the summer of 2006 and to evaluate the quality ...
Precipitation and Mesoscale Convective Systems: Explicit versus Parameterized Convection over Northern Africa
Publisher: American Meteorological Society
Abstract: AbstractPrecipitating systems are analyzed during a dust event from 9 to 14 June 2006 over northern Africa. A common analysis is applied to satellite observations and two Meso-NH simulations: one convection permitting (grid ...
Precipitation and Mesoscale Convective Systems: Radiative Impact of Dust over Northern Africa
Publisher: American Meteorological Society
Abstract: AbstractThe radiative effect of dust on precipitation and mesoscale convective systems (MCSs) is examined during a case of dust emission and transport from 9 to 14 June 2006 over northern Africa. The same method to identify ...
The Three Atmospheric Circulations over the Indian Ocean and the Maritime Continent and Their Modulation by the Passage of the MJO
Publisher: American Meteorological Society
Abstract: The passage of the Madden?Julian oscillation (MJO) over the Indian Ocean and the Maritime Continent is investigated during the episode of 23?30 November 2011. A Meso-NH convection-permitting simulation with a horizontal ...

The Atmospheric Overturning Induced by Hector the Convector
Publisher: American Meteorological Society
Abstract: AbstractThe overturning of Hector the Convector, a tropical multicellular convective system of northern Australia that regularly overshoots into the stratosphere, is synthesized at the scale of a large-eddy simulation. The ...
Giga-LES of Hector the Convector and Its Two Tallest Updrafts up to the Stratosphere
Publisher: American Meteorological Society
Abstract: he dynamics of Hector the Convector, which overshot into the stratosphere on 30 November 2005 over the Tiwi Islands, Australia, is investigated using a giga-large-eddy simulation with a 100-m cubic mesh. Individual updrafts, ...
Polar Lows over the Nordic Seas: Improved Representation in ERA-Interim Compared to ERA-40 and the Impact on Downscaled Simulations
Publisher: American Meteorological Society
Abstract: olar lows are intense high-latitude mesocyclones that form during the cold season over open sea. Their relatively small-scale and short life span lead to a rather poor representation in model outputs and meteorological ...
