NASA CYGNSS Satellites use GPS to measure Hurricane Winds

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane’s wind speed – detecting whether it will make landfall as a Category 1 or a Category 5. NASA’s Cyclone Global Navigation Satellite System (CYGNSS) fleet, launched in 2016, was designed to show whether the same GPS signals your phone uses for navigation can be used to measure winds deep within a hurricane or typhoon. The answer appears to be a resounding yes.

Weather forecasting models have gotten much better at predicting the future track of a hurricane or typhoon, but they haven’t improved at predicting its maximum wind speed, which scientists call intensity.

NASA to launch Six Small Satellites in new approach to studying Earth

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Beginning this month, NASA is launching a suite of six next-generation, Earth-observing small satellite missions to demonstrate innovative new approaches for studying our changing planet.

These small satellites range in size from a loaf of bread to a small washing machine and weigh from a few to 400 pounds (180 kilograms). Their small size keeps development and launch costs down as they often hitch a ride to space as a “secondary payload” on another mission’s rocket — providing an economical avenue for testing new technologies and conducting science.

NASA’s Global Precipitation Measurement satellite observes Typhoon Atsani building

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Typhoon Atsani was an intensifying tropical storm moving over the open waters of the Pacific Ocean on August 16th, 2015 when the GPM core observatory satellite flew overhead.

The Global Precipitation Measurement or GPM mission core satellite passed over Atsani at 06:01am UTC (2:01am EDT). GPM is managed by both NASA and the Japan Aerospace Exploration Agency.

NASA-JAXA's GPM satellite saw rainfall south of the storm's center of circulation was falling at a rate of over 90 mm (3.5 inches) per hour and cloud tops to heights of 16.8 km (10.4 miles). (SSAI/NASA/JAXA, Hal Pierce)

American Red Cross sends support to Philippines for Typhoon Response

 

American Red CrossNashville, TN – Typhoon Haiyan swept across the central Philippines on Friday leaving a trail of massive destruction in its wake. With sustained winds reported at over 145 miles per hour, and significantly stronger gusts, Haiyan was the second category 5 typhoon to strike the Philippines this year.

The typhoon affected 4.3 million people across 36 provinces. Philippine Red Cross volunteers throughout the region are reporting significant damage and a growing death toll, while the full extent of the devastation continues to unfold. Currently, 1,200 evacuation centers are housing more than 330,000 people left homeless by the storm.
