A multiscale modeling project for wind energy assessment in central Nevada has been conducted. The PSU/NCAR fifth-generation Mesoscale Model (MM5) was used in conjunction with an h-adaptive finite element model and local tower data for a 1-year cycle for the central region. The MM5 results and the local tower data are used as input into the microscale h-adaptive FEM model. The h-adaptive module...

This paper investigates the kinematic flow and precipitation evolution of a winter storm over and upstream of the Wasatch Mountains (IPEX IOP3) using a multiply nested version of the Pennsylvania State University-National Center for Atmospheric Research (NCAR) Mesoscale Model (MM5). Validation using in-situ aircraft data, radiosondes, ground-based radar, and surface observations showed that the...

Air pollution in urban areas has important implications for health and environmental management. Consequently, various methodologies have been developed for its assessment. Traditionally, simple approaches such as the box model or the Gaussian plume have been used to assess urban air quality. The use of Eulerian grid models, which provide a more realistic and comprehensive description of the ur...

Using the 3-Dimensional Variational Analysis data assimilation scheme and the Pennsylvania State University (PSU)/National Center for Atmospheric Research (NCAR) Mesoscale Model 5 (MM5) as configured and run operationally by the Air Force Weather Agency (AFWA) in the European theater, input observations were denied in three different categories: total, upper air, and surface observation denial....

A fully coupled ‘‘online’’ Weather Research and Forecasting/Chemistry (WRF/Chem) model has been developed. The air quality component of the model is fully consistent with the meteorological component; both components use the same transport scheme (mass and scalar preserving), the same grid (horizontal and vertical components), and the same physics schemes for subgrid-scale transport. The compon...
