Downslope windstorm in Iceland – WRF/MM5 model comparison [PDF]
Atmospheric Chemistry and Physics, 2011 A severe windstorm downstream of Mt. Öræfajökull in Southeast Iceland is simulated on a grid of 1 km horizontal resolution by using the PSU/NCAR MM5 model and the Advanced Research WRF model.

The impact of MM5 and WRF meteorology over complex terrain on CHIMERE model calculations [PDF]
Atmospheric Chemistry and Physics, 2009 The objective of this study is to evaluate the impact of meteorological input data on calculated gas and aerosol concentrations. We use two different meteorological models (MM5 and WRF) together with the chemistry transport model CHIMERE. We focus on the

2-way coupling the hydrological land surface model PROMET with the regional climate model MM5 [PDF]
Hydrology and Earth System Sciences, 2013 Most land surface hydrological models (LSHMs) consider land surface processes (e.g. soil–plant–atmosphere interactions, lateral water flows, snow and ice) in a spatially detailed manner.

Sensitivity of the Community Multiscale Air Quality (CMAQ) model v4.7 results for the eastern United States to MM5 and WRF meteorological drivers [PDF]
Geoscientific Model Development, 2010 This paper presents a comparison of the operational performances of two Community Multiscale Air Quality (CMAQ) model v4.7 simulations that utilize input data from the 5th-generation Mesoscale Model (MM5) and the Weather Research and Forecasting (WRF ...

MM5 simulations of a SCOS97-NARSTO episode [PDF]
Atmospheric Environment, 2003 Abstract MM5 simulations of the 4–7 August SCOS97-NARSTO ozone episode in the SoCAB showed that a relatively rare easterly upper-level background flow influenced surface wind flow directions at in-land sites. An inland-moving surface convergence zone resulted where the offshore background flow met an inland moving westerly (sea breeze plus thermal ...

Determination of Upwind and Downwind Areas of Seoul, Korea Using Trajectory Analysis
Asian Journal of Atmospheric Environment, 2010 To identify the domains that have the greatest impacts on air quality at the surface, both the upwind and downwind areas of Seoul were determined by season using refined wind fields. Four consecutive days were selected as the study period typical of each

Incremental Analysis Updates Initialization Technique Applied to 10-km MM5 and MM5 3DVAR
Monthly Weather Review, 2006 Abstract An incremental analysis updates (IAU) technique is implemented for 3-h updates of the fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5) three-dimensional variational data assimilation (3DVAR) and model system with a 10-km resolution to remove spurious gravity waves.
