The animation also shows the rainfall from the typhoons in the Pacific Ocean during the same period. (less)

Lightning is a brief but intense electrical discharge between positive and negative regions of a thunderstorm. The Lightning Imaging Sensor (LIS) on the Tropical Rainfall Measuring Mission (TRMM) satellite was designed to study the distribution and variability of total lightning on a global basis. The Optical Transient Detector (OTD) was an earlier lightning detector flying aboard the Microlab-1 spacecraft. The data shown here are compiled from LIS (1998-2002) and OTD (1995-1999) observations. Because each satellite saw only a part of the Earth at any one time, these data use complex algorithms to estimate total flash rate based on the flashes observed and the amount of time the satellite views each area. NOTE: This animation is primarily designed to be used through the Web Mapping Services (WMS) protocol. Each frame in the animation actually represents an accumulation of a number of years of data up through a particular day of the year. Because of a limitation in the WMS protocol, each frame is marked only with a single date representing the last date for which the data was accumulated. (less)

The NASA finite-volume General Circulation Model (fvGCM) is used to produce a high-resolution weather prediction system. This model has an increased accuracy of predicting the strength and location of hurricanes over other prediction methods. Several variables are predicted, including cloud cover and precipitable water in the atmosphere. Data from Hurricane Isabel was used to validate the fvGCM model. (less)

Hurricane Fabian threatened the Eastern Coast of the United States before it turned northward and hit the island of Bermuda instead. Fabian came within 50 miles to the west of Bermuda on September 5th, 2003, with sustained winds of 117 miles per hour and with gusts of up to 130 miles per hour. (less)

Hurricane Jeanne was the fourth hurricane to hit Florida during the 2004 hurricane season. This set of images shows the progression of the hurricane as it approached Florida from the Atlantic Ocean and the Caribbean Sea. When it hit the Florida coast on September 26, Jeanne was a Category 3 storm with sustained winds near 115 miles per hour. (less)

Hurricane Isabel generated large amounts of rain over the Atlantic ocean as it approached East coast of the United States in September 2003. In fact, unlike many hurricanes, most of the Isabels rainfall did not occur over land; flooding on land was caused mainly by storm surge. This animation shows accumulation of rainfall from the hurricane--each frame shows the total amount of rain since the start of the measurement period. Rain from other sources has been masked out, so the hurricane track is clearly visible as the storm moves across the Atlantic. (less)

Satellite data can gauge the health of plants, which is a good indicator of drought. The Normalized Difference Vegetation Index (NDVI) measures how dense and green plant leaves are. NDVI images are useful as a measure of drought when compared to "normal" plant health. Scientists calculate average NDVI values for an area to find out what is normal at a particular time of year. This animation uses satellite imagery to show changes in vegetation between 1999 and 2003. In 2002, drought had settled across the Midwest. Large dark brown sections of eastern Colorado show where vegetation was less lush and healthy than normal. This version of the visualization is a wide view showing the western United States. The data were measured by the vegetation instrument on Europe's SPOT-4 satellite, and were provided by DigitalGlobe-SPOT under agreement with the U.S. Department of Agriculture Foreign Agricultural Service (USDA-FAS).

Wind Vectors for Hurricane Erin (WMS)

Wind Vectors for Hurricane Erin (WMS)

This visualization shows wind vectors for Hurricane Erin on September 10, 2001. Wind direction and speed are represented by the direction and speed of moving arrows, respectively. This animation represents a single measurement taken by the SeaWinds instrument on the QuikSCAT satellite, taken at 14:27:00 UTC on September 10, 2001. The WMS version of this animation which is available through the SVS Image Server (http://aes.gsfc.nasa.gov) presents this animation with a different timestamp for each frame in order to more easily present the images as an animation. It should be noted that each frame really has a time stamp of 2001-09-10 14:27:00 UTC. (less)
