NASA's Hurricane Twitter, which posts the web site's updates, exceeded 200,000 followers recently - a landmark that just a few NASA Twitter accounts have reached.
This visualization shows sea surface current flows. The flows are colored by corresponding sea surface temperature data.
The Saffir-Simpson Hurricane Wind Scale is the standard used to measure hurricane intensity, and this year, the National Oceanic and Atmospheric Administration (NOAA) is making a modification of the scale.
Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.
A monsoon trough continues to drench northeastern Australia and NASA's Tropical Rainfall Measuring Mission (TRMM) satellite measured and calculated the rainfall in the region.
For 12 years, GOES-11 tracked weather and severe storms that affected the U.S. West Coast, Hawaii and the Pacific region.
The 2011 hurricane season is now available in one video from NOAA.
The data from the TOPEX/Poseidon and Jason missions captured an image of the current La Niña (in blue) on Nov. 3, 2011. Cooler than normal waters stretched over the eastern equatorial Pacific Ocean.
Within just the past week, the East Pacific has seen a resurgence in tropical activity with the formation of three tropical systems
NASA's new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission's anticipated discoveries
During the first two weeks of September, and the peak of the Atlantic Hurricane season, NASA satellites were keeping tabs on a number of tropical systems
A group of environmental scientists are preparing for a multi-year NASA airborne science investigation of Atlantic hurricane formation and intensity.
Traveling northward from the Gulf of Mexico, Tropical Storm Lee carried heavy rain to the northeastern U.S. in early September 2011.
It's what Bill Patzert, a climatologist and oceanographer at NASA's Jet Propulsion Laboratory in Pasadena, Calif., likes to call a "La Nada" ...
One of the potential benefits of Hurricane Irene may be to help extinguish a large fire burning in the Great Dismal Swamp.
As Hurricane Irene rumbles through the Atlantic Ocean, it needs fuel to sustain itself.
In early August 2005, "Katrina" was just a name. By September, it had become synonymous with the costliest tropical cyclone in U.S. history.
NASA's TRMM satellite identified large areas of heavy rainfall within Hurricane Irene affecting the Bahamas, and helped forecasters identify its "hidden" eye.
Like mercury in a thermometer, ocean waters expand as they warm.
Extreme drought continues to dog Lone Star State as tropical storm fades.
