   Hurricane Noel data in a Virtual Environment
    Click previews for larger image.

The data for this environment was obtained from:
- The Hurricane Research Division's Mission Catalog for Hurricane Noel at the Atlantic Oceanographic and Meteorological Laboratory
- The National Hurricane Center's Tropical Cyclone Report at NHC
- Noel's track from the Weather Underground's 2007 Storm Archive

You are looking north from above the north end of South America. The cones are the locations of Noel every 6 hours from October 24, 2007 to November 6, 2007. The cyan are tropical depression (<39mph) and the green are tropical storm (39-73mph). The yellow, purple, and pink lines rising from the Carribean Island are recon missions shown with a verticle exaggeration of 40 which were flown on October 29-31, 2007. The yellow and green flight lines go down into Biloxi, MS in the distance. The "system" from which this snapshot was captured draws the flight line time accurately. In other words you see the yellow line rise from the Carribean Island at the proper date/time (the timebar legend is still under development; it will show progression of date/time based on data input), the line intersects the hurricane several times, then progress to Biloxi (Keesler AFB). You can see the grey line go up the eastern US coast, which shows where the storm will go (so this is a retrospective visualization). It provides context.



By November 2, 2007, there has been a recon (shown in blue) flight from Keesler. The hurricane has progressed to a Category 1 hurricane (74-95mph) shown in yellow. The red "paper airplane" is a simple temporary icon to show the flight line direction.



We've now moved over the eastern US and zoomed into a path for which we were given high-resolution temporal data (yellow line). Without the ability to fly around in the environment, it is hard to see whether the plane was going up-and-down or back-and-forth, but it's clear it flew through the hurricane at least one point on November 2 and 3, 2007.



We've just moved to the east side of the hurricane path and are now looking west.



top down view. Now we can see the yellow path starts at Wallops Island, for example.



Starting back over, this time showing the dropsonde locations. We still have to work on visualizing the data collected along the dropsonde path. The snapshots do not show how well the dropsondes align with the flight path. As the plane flies along, the dropsondes appear.

An exocentric view of what one would see in the CAVE (ours is called the VERTEX). The imagery would be mapped onto the bottom, front, and 2 sides of the virtual box. You are looking west.
