Weather Conditions: Preview
• Pre-episode: subtropical H slow speeds, low mixing depth
• Episode: shallow Persian thermal trough penetrates H withdraws increased surface HPG
augmented westerly sea breeze front inland elevated ozone concentration
EPA uMM5 at SJSU • As close as possible to RAMS set-up

• Initialized & updated every 6 hr with ECMWF fields
• Topography from GTOPO30 project, horizontal grid spacing of 30 sec (approx 1 km2)
• Land-use & DTM (25 x 25 m2) for 2nd & 3rd grids
• MM5 Met fields will also be used as input to CAMx • Meso wind convention: flag is 5 m/s & full barb is 1 m/s
CAMx: version 3.10
• Map projection: Polar Stereographic
• Grid area: 270 x 370 km2. Cells 5 X 5 km2
• Transport algorithm: area preserving flux-form advection solver (Bott 1989).

Future Plans:
GIS/RS from TAU, ARIJ, an EPRI to determine gridded fields of sfc characteristics (e.g., z0, ε, α, LU/LC) for uMM5 and CAMx
Urbanized EPA MM5 meso-model (uMM5xx) will simulate additional flow cases on the 106 CPU SJSU cluster
CAMx will be run with current precursor emissions using output from the RAMS and uMM5xx simulations
ARIJ, EPRI, & HUJI planners will identify future emission scenarios from 2010 & 2020 population conditions (when regional populations will be 2 x present values) to test in CAMx
Jordanian scientists will become part of project
