NASA Gets ''Eyed'' by Major Hurricane Jose

and has no comments yet.
NASA's Aqua satellite captured clear view of the eye of Hurricane Jose at it moved toward the Leeward Islands and strengthened into a Category 4 Hurricane on the Saffir-Simpson Hurricane Wind Scale. Aqua also analyzed the storm in infrared light showing powerful storms around the center, capable of heavy rainfall.

NASA Finds Jose Strengthening into a Hurricane

and has no comments yet.
The Global Precipitation Measurement mission or GPM core satellite has been providing rainfall rates and cloud heights in tropical cyclones, and recently found towering thunderstorms that indicated strengthening in Tropical Storm Jose. Those "hot towers" were an indication the storm was strengthening and it later became a hurricane.

NASA Looks at Hurricane Irma's Heat Engine

and has no comments yet.
On September 5, 2017 at 1 p.m. EDT (1700 UTC) the radar on the Global Precipitation Measuring Mission (GPM) satellite captured a 3-D view of the heat engine inside of category-5 Hurricane Irma. Under the central ring of clouds that circles the eye, water that had evaporated from the ocean surface condenses, releases heat, and powers the circling winds of the hurricane. The radar on the GPM satellite is able to estimate how much water is falling as precipitation inside of the hurricane, which serves as a guide to how much energy is being released inside the hurricane's central "heat engine."

GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands

and has no comments yet.
The National Hurricane Center (NHC) upgraded a low pressure area in the far eastern Atlantic Ocean to tropical storm Irma on August 30, 2017 at 11 a.m. EDT (1500 UTC).Tropical cyclones that form in that part of the Atlantic Ocean are often the largest and most powerful hurricanes of the season. Hurricanes Ivan (2004), Isabel (2003), Hugo (1989) and Allen (1980) are examples of past powerful hurricanes that formed near the Cape Verde islands.

NASA Shows How Harvey Saturated Areas in Texas

and has no comments yet.
NASA analyzed the soil moisture in southeastern Texas before and after Harvey made landfall and found the ground was already somewhat saturated. NASA-NOAA’s Suomi NPP Satellite provided a night-time look at Harvey after it moved into the Gulf of Mexico, and NOAA’s GOES East satellite provided a look at the storm after it made its final landfall near the Texas-Louisiana border on Aug. 30.

NASA Calculates Tropical Storm Harvey's Flooding Rainfall

and has no comments yet.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland, an analysis of Hurricane Harvey's tremendous rainfall was created using eight days of satellite data.NASA's Integrated Multi-satellitE Retrievals for GPM or IMERG product is used to make estimates of precipitation from a combination of space-borne passive microwave sensors, including the GMI microwave sensor onboard the Global Precipitation Measurement satellite GPM core satellite, and geostationary IR (infrared) data.

NASA Look at Tropical Storm Pakhar in Infrared Light

and has no comments yet.
NASA’s Aqua satellite passed over Tropical Storm Pakhar and gathered temperature data to determine the location of the most powerful storms within. Pakhar has triggered a number of warnings throughout the Philippines as the storm moves closer.Philippines warnings include Public storm warning signal #1 for the Luzon provinces of Cagayan including Babuyan group of islands, Apayao, Ilocos Norte, Nueva Ecija, Pangasinan, Northern Quezon including Polillo island, and Camarines Norte. Public storm warning signal #2 is in effect for the Luzon provinces of Isabela, Aurora, Quirino, Kalinga, Mountain Province, Ifugao, Ilocos Sur, Benguet, Abra, La Union and Nueva Vizcaya.

NASA Gets an In-Depth Look at Intensifying Hurricane Harvey

and has no comments yet.
As Hurricane Harvey continued to strengthen, NASA analyzed the storm’s rainfall, cloud heights and cloud top temperatures. NASA’s GPM and Aqua satellite provided information while an animation of GOES-East satellite imagery showed Harvey’s progression toward the Texas coast. Harvey's intensification has been aided by movement through an environment that includes low vertical wind shear and the warm waters in the Gulf of Mexico.

NASA Gets a Final Look at Hurricane Gert's Rainfall

and has no comments yet.
Before Hurricane Gert became a post-tropical cyclone, NASA got a look at the rainfall occurring within the storm. After Gert became post-tropical NOAA’s GOES-East satellite captured an image as Gert was merging with another system.The Global Precipitation Measurement mission or GPM core observatory satellite provided rainfall information on Hurricane Gert on August 16, 2017 at 5:37 p.m. EDT (2137 UTC). At that time, Gert was a strong category two hurricane with maximum sustained winds of about 93.5 mph (85 knots).
