The intensity of the storm is depicted through color. Purple is the weakest classification, Tropical Depression, where winds are less then 39 miles per hour. Blue represents a Tropical Storm with winds between 39 and 73 miles per hour. Blue-Green shows a Class 1 Hurricane with winds between 74 and 95 miles per hour. Green displays a Class 2 Hurricane with winds between 96 and 110 miles per hour. Yellow is a Class 3 Hurricane where winds are sustained between 111 and 130 miles per hour. Orange is a Class 4 Hurricane with winds between 131 and 154 miles per hour.

The colors on the ocean represent the sea surface temperatures, and satellite images of the hurricane clouds are laid over the temperatures to clearly show the hurricane positions. Orange and red depict regions that are 82 degrees F and higher, where the ocean is warm enough for hurricanes to form. Hurricane winds are sustained by the heat energy of the ocean, so the ocean is cooled as the hurricane passes and the energy is extracted to power the winds. A hurricane can experience a dramatic reduction in wind speed when it crosses the cold track of a previous hurricane. However, in this case, the cold water track from Fabian warmed up before Isabel crossed it, so Isabel's winds did not decrease. The sea surface temperatures were measured by the AMSR-E instrument on the Aqua satellite, while the cloud images were taken by the Imager on the GOES-12 satellite. || ", "hits": 28 }, { "id": 20010, "url": "https://svs.gsfc.nasa.gov/20010/", "result_type": "Animation", "release_date": "2003-12-09T12:00:00-05:00", "title": "Particulates Effect on Rainfall", "description": "Normal rainfall droplet creation involves water vapor condensing on particles in clouds. The droplets eventually coalesce together to form drops large enough to fall to Earth. However, as more and more pollution particles (aerosols) enter a rain cloud, the same amount of water becomes spread out. These smaller water droplets float with the air and are prevented from coalescing and growing large enough for a raindrop. Thus, the cloud yields less rainfall over the course of its liftime compared to a clean (non-polluted) cloud of the same size. The split screen compares a normal rain producing cloud (left) with the lack of rain produced from a cloud full of aerosols from pollution. || ", "hits": 452 }, { "id": 20013, "url": "https://svs.gsfc.nasa.gov/20013/", "result_type": "Animation", "release_date": "2003-12-09T12:00:00-05:00", "title": "Urban Rainfall Effect on Coastal Cities", "description": "Cities tend to be 1-10 degrees Fahrenheit warmer than surrounding areas.
