Introduction

• JSUMP will develop web sites to deliver MM5 and
  COAMPS output
• Mesoscale modeling requires two-tier approach
  (QG, SG /PBL will be used)
• Future 3-D products
• ftp access
• Will allow adaptive computation
• Testing (usability analysis)

3
MODELS

• Fifth Generation Mesoscale Model (MM5)
• Coupled Ocean/Atmosphere Mesoscale Prediction
  System (COAMPS)

4
Triple-Nested Domains for MM5 and
COAMPS (Centered Gulf Cost, Used for sea-breeze
simulation)
5
MM5

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

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 Red Hat, and SGI
• Applicable to any region in the World
• Gulf of Mexico, Korea, Persian Gulf
• Public Domain Software gt on the web

8
MM5 12 hour forecast simulation of dew point and
pressure at surface level using GrADS software

(http//weather.jsums.edu)
9
MM5 run (triple-nested inner domain 9 Km) 00
hours dew point forecast at 850 mb for
8/3/00 httpweather.jsums.edu
10
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
• Proprietary Software gt not web site/ not
  operationalgtrestricted access

11
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 and LINUX

12
18 hours forecast wind field simulation COAMPS
13
Sample output JSUMP/HPVCI COAMPS (18 hours
forecast vertical motion)
14
Sample Output JSUMP/HPVCI COAMPS (21 Hour
Advection Forecast)
15
VISUALIZATION SOFTWARE

• 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

• 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)

16
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
  (using GIS)
• ftp capabilities
• http//weather.jsums.edu, (LINUX)
• http//betsy.jsums.edu/hafner/oper5.html, (SGI)

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

19
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,
  not computer, controlling interactive session)
• allow users to create/customize their maps
• JSU as clearinghouse institution
