Several aspects of modeling dynamics at the mesoscale level are discussed: (1) The construction of a mesoscopic description of fluid dynamics. The mesoscale dynamics consists of free streaming interrupted by multi-particle collisions. The multi-particle collisions are carried out by performing random rotations of particle velocities in predetermined cells in a manner that conserves mass, moment...
The objective of this work was to assess the accuracy of various coupled mesoscale-microscale wind flow modeling methodologies for wind energy applications. This is achieved by examining and comparing mean wind speeds from several wind flow modeling methodologies with observational measurements from several 50 m met towers distributed across the study area. At the mesoscale level, with a 5 km r...
Increasing on-chip transistor densities allow for a myriad of design choices for modern multicore processors. However, conducting a meaningful design space exploration of large systems with detailed cycle-accurate simulations using large, complex workloads can be very time-consuming and can adversely impact product schedules. This is due to three main reasons: 1) the high (human) cost of develo...
Numerical simulations with the NCAR=PSU Mesoscale Model 5 (MM5) were performed to study a large-amplitude gravity wave event that occurred on 4 January 1994 along the East Coast of the United States. Results from the MM5 control simulation using a 12-km mesh resolution compared well with the synoptic and mesoscale observational analysis. The simulated gravity waves displayed timing, location, w...
The authors characterize impacts on heat in the ocean climate system from transient ocean mesoscale eddies. Their tool is a suite of centennial-scale 1990 radiatively forced numerical climate simulations from three GFDL coupledmodels comprising the ClimateModel, version 2.0–Ocean (CM2-O), model suite. CM2-O models differ in their ocean resolution: CM2.6 uses a 0.18 ocean grid, CM2.5 uses an int...
An intense small-scale low pressure system that moved across portions of the midwest United States is examined. The system produced a continuous band of significant snowfall, typically only 50 km wide but extending over 1500 km in length. The system traveled across the Iowa Department of Transportation surface mesonetwork, allowing high-resolution surface analyses that show a closed circulation...
Two-dimensional (2D) and three-dimensional (3D) cloud-resolving model (CRM) simulations are conducted to quantify the enhancement of surface sensible and latent heat fluxes by tropical precipitating cloud systems for 20 days (10–30 December 1992) during the Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE). The mesoscale enhancement appears to be analogo...
