MESO continues to expand its routine production of real-time atmospheric simulations. It is now executing a nested simulation with the MASS model twice per day. These simulations are executed on a 600 MHz Alpha 21164 processor system running the Linux operating system. The outer 44 km grid covers the entire 48-state region of the United States while the high resolution 11 km grid is executed over the northeastern US. The full set of output from the 00 UTC simulation is available by approximately 2 AM EST and the complete output from the 12 UTC simulation is available be approximately 2 PM EST. Output from these simulations is used to generate a variety of weather forecast products. An example is the forecast of canopy temperatures for agricultural applications. In this application the output from the 3-D MASS simulation is used to drive a 1-D canopy model that can generate predictions of temperature, leaf wetness and other variables for specific canopies. In addition to the twice per day MASS simulations, MESO is also executing a nested run of the MM5 model from a 0000 UTC initialization. The MM5 simulations are executed on a 533 MHz Alpha 21164 processor system. The MM5 currently uses a 45 km coarse grid over the eastern two-thirds of the United States and a 15 km fine grid over the northeastern US. Output from this run can be viewed from MESO's MM5 page. An example of the 24-h forecast of near-surface air temperature and winds from a MM5 15 km real-time simulation is shown in the above image. The newest addition to MESO's family of real-time models is the FOREWIND model. It is still under development but is producing experimental daily simulations from a 0000 UTC initialization on most days. FOREWIND is a sophisticated boundary layer model intended to run at high horizontal resolution over small regions to simulate local winds for a variety of applications. Output from this model can be accessed from the FOREWIND home page. The OMEGA model may be added to the suite of real-time models in the future. OMEGA is an adaptive grid non-hydrostatic model. |
MESO is currently in the second year of a two year research project to refine its Heated Cloud Rise Model (HCRM) that it developed in a joint venture with SECA, Inc. of Huntsville, AL as a tool to simulate the rise and dispersion of rocket exhaust clouds. The HCRM is a complete non-hydrostatic atmospheric model that has been modified to incorporate the physics and chemistry that is unique to rocket exhaust clouds. The original version of the model was extensively validated by executing simulations for rocket launch cases that were extensively measured and documented as part of the Government's rocket exhaust Model Validation Program (MVP). The objective of the current project is to refine the model physics to improve the accuracy of the details of the simulations, increase the model's computational efficiency so that it can be executed quickly on desktop computers and develop a graphical user interface to permit model users to easily configure and initiate a simulation. A sample of the model's output is shown in the image below. This image created with University of Wisconsin's VIS5D package depicts the 10 ppm isosurface of HCl (Hydrogen Chloride) vapor two minutes after a launch of a Titan IV vehicle at the Kennedy Space Center. This simulation used a grid with grid cell sizes of 75 m in all three dimensions. The blue region underneath the cloud denote a water surface and the green depicts the land surface.
