Astronaut experiences tropical storm Barry threatening the Gulf Coast
A large number of climate satellites – and not less than one astronaut – are watching Tropical Storm Barry because it approaches the coast of the Gulf of Mexico.
Barry is transferring slowly northwesterly to the Louisiana coast at the moment (July 12) and is predicted to move north and into the decrease Mississippi Valley, in response to a public discover issued by the Nationwide Hurricane Middle of the Nationwide Oceanic and Atmospheric Administration.
The winds of a tropical storm are a lot weaker than these of a hurricane, however the primary risk is what emerges from NASA's NASA astronaut Christina Koch's picture shared on Twitter from her standpoint. 39 remark on the Worldwide House Station: an unlimited expanse of clouds.

In response to the Nationwide Hurricane Middle, these clouds threaten areas of Louisiana and Mississippi with 25 to 50 centimeters of rain. Some locations can see as much as 64 centimeters. Storm surges, gusts of wind, and a few tornadoes are additionally potential penalties of the storm being monitored by the middle.

The Nationwide Hurricane Middle depends partly on a mess of satellites to foretell the place tropical storms and hurricanes will type, how they are going to develop, and the place they are going to ultimately grow to be a risk. One in every of these satellites is a joint mission of NASA and the Japan Aerospace Exploration Company, known as GPM Core Observatory.
This satellite tv for pc makes use of a microwave instrument to estimate the quantity of rain produced by cloud moisture. It additionally makes use of a radar instrument to measure cloud high top, which scientists can use to evaluate the danger of thunderstorms.
