Hurricane Ike on September 4, 2008
|
NASA's TRMM spacecraft observed this view of Hurricane Ike on September 4, 2008 as it strengthened in the Atlantic. At this time the storm was an extremely dangerous category 4 hurricane with sustained winds of 125 knots (143 mph) and a pressure reading of 935 millibars. Hurricane-force winds were extending outward 45 miles from the center, while tropical storm-force winds extend up to 140 miles. The cloud cover in this animation is taken by TRMM's Visible and Infrared Scanner(VIRS) and the GOES spacecraft. The rain structure is taken by TRMM's Tropical Microwave Imager (TMI) and TRMM's Precitation Radar(PR) instruments. TRMM looks underneath of the storm's clouds to reveal the underlying rain structure. Blue represents areas with at least 0.25 inches of rain per hour. Green shows at least 0.5 inches of rain per hour. Yellow is at least 1.0 inches of rain and red is at least 2.0 inches of rain per hour.
