INTRODUCTION

• JSUMP has developed websites to deliver MM5 and
  COAMPS output (datasets, maps, user defined
  products, etc.)
• Mesoscale modeling requires two-tier approach
  (QG, and SG /PBL)
• Available 3-D products, VR simulations, data
  sets, weather map, computer code, ftp access,
  etc.
• Will allow adaptive computation (make-your-own
  type products)
• Beta-testing (usability analysis before final
  release)

MODELS
Triple-Nested Domains for MM5 and
COAMPS (Centered Gulf Coast, Used for sea-breeze
simulation)
(Grid-point distance 3Km, 9Km, 27 Km)
4
MM5

• Developed by PSU/NCAR
• non-hydrostatic
• terrain-following
• (sigma coordinates)
• designed to simulate regional-scale,
• synoptic scale

http//fog.jsums.edu/mm5
5
MM5 (continued)

• Inner Domain Grid Number 67x79, Grid Size 9 Km
• Outer Domain Grid Number 91x87, Grid Size 27 Km
• Runs and data processed in Linux, and SGI
• Applicable to any region in the World Gulf of
  Mexico, Korea, Persian Gulf
• Public Domain Software gt on the web

COAMPS

• Coupled Ocean/Atmosphere Mesoscale Prediction
  System
• Short-term forecasts (now-cast to 48 hours)
• Applicable anywhere in the world
• Can use data from real-time simulations, NOGAPS
  output, most recent COAMPS output for first guest
• Formerly proprietary Software gt now public
  domain.

9
COAMPS (continued)

• Inner Domain Grid Number 43x43, Grid Size 3 Km
• Mid Domain Grid Number 43x43, Grid Size 9 Km
• Outer Domain Grid Number 49x49, Grid Size 27 Km
• Runs in SGI (origin 2100, IRIX 6.5.10) and LINUX
  (Red Hat 6.2 7.1)

VISUALIZATION SOFTWARE

• Vis5D
• Visualizes numerical models, observations,
  gridded, and irregularly spaced data
• Data can 1-dimensional (one time-step, one
  vertical level, or one physical variable
• Data can be 5-dimensional (width, height, length,
  time, physical variable)

• GrADS (The Grid Analysis and Display System)
• Software represents each gridded and station data
  point as 4-dimensional fields (latitude,
  longitude, level height, and time)
• Public domain software
• Runs in any UNIX or DOS based PC

12
THE SITES

• Developed to address the needs of users with
  various levels of knowledge
• Three main links Beginners, Advance, Expert
• Products according to knowledge level (different
  for each link)
• Glossary for all links
• Great potential for research and students
  homework
• Users will be able to create their own maps and
  products (using GIS)
• ftp capabilities
• http//weather.jsums.edu, http//rainbow.jsums.edu
  
• http//fog.jsums.edu/mm5
• http//viz.jsums.edu/coamps

13
TWO-TIER APPROACH

• QG (Quasi-Geostrophic Theory), not valid around
  fronts, in the tropics, troughs, and ridges
• SG (Semi-Geostrophic Theory) where QG is not
  valid able to simulate Planetary Boundary Layer
  scale events (e.g., convective initiation, sea
  breeze, etc)
• Thanks to this, JSU/HPVCIs models are able to
  run more accurate simulations and produce better
  forecasts

14
TESTING

• Will conduct Usability Analysis
• Identify level of knowledge of users
• Identify users goals when visiting the sites
• Ways to address users goals (researchers,
  students, etc.)
• Why do testing?
• Improve human-computer interactions (e.g., user,
  instead of computer, in charge of interactive
  session)
• allow users to create/customize their maps
• JSU as clearinghouse institution

15
FUTURE

• Beta-testing of sites and final release
• Access products (ftp/web data sets, 3-D maps and
  loops, make-your-own, etc.)
• Linked to HPVCI JSU MP Distance Learning Project
• JSU MP as clearinghouse of similar projects
• Implementation of new technologies (forecasting,
  modeling, etc.)
