Gaston is currently sitting smack in the middle of the Atlantic Ocean churning away. Currently it is not near any landmasses and is at tropical storm status having weakened slightly from hurricane force.
Depending on the intensity track of Typhoon Lionrock, it could pass over Japan with the strength of a lion or or the weakness of a lamb. The intensity track is not clear as yet and some forecasters have it remaining a stronger storm while others have it downgrading significantly in intensity.
When NASA's Aqua satellite passed over the tropical low pressure area known as System 99L it was located over Hispaniola. The AIRS instrument aboard Aqua analyzed the low pressure area in infrared light.
The Global Precipitation Measurement mission or GPM core satellite analyzed Tropical Storm Lester after it became the 12th named storm of the 2016 eastern Pacific Ocean on Aug. 25. GPM, a joint mission between NASA and the Japan Aerospace Exploration Agency, analyzed Lester's rainfall rates and cloud heights.
Gaston was a hurricane when the Global Precipitation Measurement mission or GPM core satellite passed overhead and found heavy rain occurring in the storm. GPM imagery also showed that wind shear was stretching the storm out and making it appear elongated from space.
When NASA's Aqua satellite passed over the eastern Pacific Ocean it looked at a newly developed tropical depression that would later strengthen into Tropical Storm Lester. Aqua analyzed the depression with an infrared eye and saw indications it was strengthening.
Typhoon Lionrock's rainfall rates and cloud heights were analyzed as it continued to intensify when the Global Precipitation Measurement mission or GPM core satellite passed overhead.
NASA analyzed the rainfall and cloud heights in an area of low pressure designated as System 99L that bringing rains and gusty winds to Puerto Rico, Hispaniola, Turks and Caicos and other islands in the Atlantic Ocean and northeastern Caribbean Sea today, Aug. 25.
Tropical Depression 14W was absorbed by another nearby tropical low pressure system in the Northwestern Pacific Ocean as NASA's Aqua satellite passed overhead.
Astronomers using ALMA surveyed dozens of young stars - some Sun-like and others approximately double that size - and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks. In contrast, the lower-mass, Sun-like stars have debris disks that are virtually gas-free.
