Dust Dampens Hurricane Formation

Published April 18, 2007

Warm sea surface temperatures help fuel hurricanes, and in 2006, those temperatures were cooler than expected. Why the difference between 2005 and 2006? William Lau of NASA Goddard Space Flight Center and Kyu-Myong Kim of University of Maryland-Baltimore County think the answer comes from the Sahara, namely dust.

La Niña In Progress

Published February 9, 2006

La Niña is an occurrence of unusually cold water temperatures in the Pacific Ocean along the equator (the precise area affected is outlined in black in the image above). La Niña and its opposite, El Niño, are linked to seesaw variations in air pressure over the tropical Pacific and affect weather patterns across the globe. NASA monitors developing El Ni&ntidle;o and La Niña events by observing sea surface temperatures. This image compares the water temperatures observed in late January 2006 to long-term average conditions for that time of year. The recent data were collected by the Advanced Microwave Scanning Radiometer for EOS (AMSR-E). Red shows where sea surface temperatures are warmer than normal and blue where they are colder than normal.

2005 Atlantic Hurricane Season

Published December 17, 2005

The 2005 Atlantic Hurricane season broke record after record: most named storms, lowest pressure measured in the Atlantic, longest-lived December hurricane, and the list goes on. This image provides a summary of the season, with the track of each named storm marked in black. In all, 30 tropical depressions, tropical storms, and hurricanes formed in 2005. Of these, 26 were named storms, a status given to tropical storms and hurricanes.
