South-eastern Australia covers approximately 14% of Australia land mass, and is very important for Australia’s community and economy. In this work, the Weather Research and Forecasting (WRF) regional model was run to simulate the severe drought that happened and then (partially) recovered in this region from 2000 through 2008. The model used the following physics schemes: WRF Single Moment 5-cl...

The Weather Research and Forecast (WRF) model was run over South-east Australia from 1985 through 2008. The model used the following physics schemes: WRF Single Moment 5-class microphysics scheme; Rapid Radiative Transfer Model longwave radiation scheme; Dudhia shortwave radiation scheme; Monin-Obukhov surface layer similarity; Noah land-surface scheme; Yonsei University boundary layer scheme a...

Global WRF (GWRF) is an extension of the mesoscale Weather Research and Forecasting (WRF) model that was developed for global weather research and forecasting applications. GWRF is being expanded to simulate atmospheric chemistry and its interactions with meteorology on a global scale. In this work, the ability of GWRF to reproduce major boundary layer meteorological variables that affect the f...

mineral dust is produced from both natural and anthropogenic sources. dust aerosols can be transported over long distances in the atmosphere. they reduce the incident shortwave radiation to the surface by absorbing and scattering the solar radiation; thereby leading to a cooling effect at the surface and lower tropospheric temperature. on the other hand, by absorption and re-emission of longwav...

The Weather Research and Forecasting (WRF) modelling system is developed as a collaborative partnership between the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (the National Centers for Environmental Prediction (NCEP) and the Forecast Systems Laboratory (FSL)), the Air Force Weather Agency (AFWA), the Naval Research Laboratory, Oklahoma U...

Abstract The number of solar power plants has increased in West Africa recent years. Reliable reanalysis data and short-term forecasting irradiance from numerical weather prediction models could provide an economic advantage for the planning operation plants, especially data-poor regions such as Africa. This study presents a detailed assessment different shortwave (SW) radiation schemes Weather...

A thorough understanding of the dynamics of cirrus cloud formation is needed in order to parameterize these clouds accurately in numerical models. The scales at which cirrus clouds develop affect their treatment within the coarse resolution climate models, which typically have grid-point separations on The model used for this experiment is the non-hydrostatic verthe order of 200 km. There is a ...

In order to improve the representation of ozone absorption in the stratosphere of the MAECHAM5 general circulation model, the spectral resolution of the shortwave radiation parameterization used in the model has been increased from 4 to 6 bands. Two 20-years simulations with the general circulation model have been performed, one with the standard and the other with the newly introduced paramete...

Estimating the impact of radiation transport through cloud sides on the global energy budget is hampered by the lack of a fast radiation scheme suitable for use in global atmospheric models that can represent these effects in both the shortwave and longwave. This two-part paper describes the development of such a scheme, which we refer to as the Speedy Algorithm for Radiative Transfer through C...
