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 Same‐Source Parallel MM5 [PDF]
Scientific Programming, 2000 Beginning with the March 1998 release of the Penn State University/NCAR Mesoscale Model (MM5), and continuing through eight subsequent releases up to the present, the official version has run on distributed ‐memory (DM) parallel computers. Source translation and runtime library support minimize the impact of parallelization on the original model source

GFDL-Type Typhoon Initialization in MM5
Monthly Weather Review, 2002 Abstract The Geophysical Fluid Dynamics Laboratory (GFDL) hurricane initialization algorithm is implemented in the community fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5). This work is applied to the MM5-based Regional Data Assimilation and Prediction System model (RDAPS), the Korea ...

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.

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

Evaluation of Interregional Transport Using the MM5–SCIPUFF System
Journal of Applied Meteorology, 2004 Abstract Improved understanding of transport issues and source–receptor relationships on the interregional scale is dependent on reducing the uncertainties in the ability to define complex three-dimensional wind fields evolving in time.

Tracer Advection Using Dynamic Grid Adaptation and MM5 [PDF]
Monthly Weather Review, 2005 Abstract A dynamic grid adaptation (DGA) technique is used to numerically simulate tracer transport at meso- and regional scales. A gridpoint redistribution scheme is designed to maximize heuristic characteristics of a “good” grid. The advective solver used in conjunction with the DGA is the multidimensional positive definite advection ...
