Urban canopy models (UCMs) are being used as urban-climate prediction tools for different applications including outdoor thermal comfort and building energy consumption. To take advantage of their low computational cost, UCMs are often forced offline without being coupled to mesoscale atmospheric simulations, which requires access to meteorological information above the urban canopy layer. This...

Submitted for the APR09 Meeting of The American Physical Society Turbulent transport of trapped electron modes in collisionless magnetized plasma YONG XIAO, University of California, Irvine — A prominent candidate for the electron heat transport in high temperature toroidal plasmas is collisionless trapped electron mode (CTEM) turbulence. Our large scale simulations of CTEM turbulence using gyr...

In this talk, I will present recent results from a project led at NASAfGSFC, in collaboration with NASAfMSFC and JHU, focused on the development and application of an observation-driven integrated modeling system that represents aerosol, cloud, precipitation and land processes at satellite-resolved scales. The project, known as the NASA Unified WRF (NU-WRF), is funded by NASA's Modeling and Ana...

Mesoscale analysis of surface observations and mesoscale modeling results show that the 10–11 June squall line, contrary to prior studies, did not form entirely ahead of a cold front. The primary environmental features leading to the initiation and organization of the squall line were a low-level trough in the lee of the Rocky Mountains and a midlevel short-wave trough. Three additional mechani...

Two numerical simulations were performed to study the ability of a high-resolution mesoscale model to predict the track and structure of Hurricane Isabel over North Carolina. One simulation (Control) used standard NCEP climatologically-based sea surface temperature (SST) data for the lower boundary condition while another simulation (Experimental) prescribed real-time high-resolution SST data f...

Through observing system simulation experiments, this two-part study exploits the potential of using the ensemble Kalman filter (EnKF) for mesoscale and regional-scale data assimilation. Part I focuses on the performance of the EnKF under the perfect model assumption in which the truth simulation is produced with the same model and same initial uncertainties as those of the ensemble, while Part...

Avissar, R. and Pielke, R.A., 1991. The impact of plant stomatal control on mesoscale atmospheric circulations. Agric. For. Meteorol., 54: 353-372. Only a few numerical studies with mesoscale atmospheric models have been undertaken to explore the influence of vegetation on the generation and modification ofmesoscale atmospheric circulations. Nevertheless, these few studies have demonstrated the...

In-mold assembly process has been used for manufacturing articulated structures at the macro scale. But the in-mold assembly process at the mesoscale behaves differently and poses new challenges due to reduced structural rigidity of the mesoscale premolded component. One of the major challenges that need to be addressed is that of the plastic deformation of the premolded component during the se...

In the stably stratified interior of the ocean, mesoscale eddies transport materials by quasiadiabatic isopycnal stirring. Resolving or parameterizing these effects is important for modeling the oceanic general circulation and climate. Near the bottom and near the surface, however, microscale boundary-layer turbulence overcomes the adiabatic, isopycnal constraints for the mesoscale transport. I...

The applicability of linearized axisymmetric dynamics to the intensification and structure change of tropical cyclones is investigated. The study is motivated by recent work that presented axisymmetric solutions to the linearized, non-hydrostatic, vortex-anelastic equations of motion (the so-called 3DVPAS model). The work called into question the importance of a recently proposed nonlinear, sys...
