Rare tropical cyclone forms

The second–ever known tropical cyclone in the South Atlantic Ocean can’t escape satellite eyes, and this past weekend, the Geostationary Operational Environmental Satellite, GOES-12 captured a visible image of Tropical Storm 90Q which was located off the coast of Argentina.

GOES-12 satellite captured an image of the Tropical Storm 90Q on Friday last week when it was more than 2000kms east of Buenos Aires, Argentina.

GOES-12 is operated by the National Oceanic and Atmospheric Administration, and images are created by NASA’s GOES Project, located at NASA’s Goddard Space Flight Center, Greenbelt, Md.

Tropical Storm 90Q is now moving quickly in a southeasterly direction and is starting to interact with a mid-latitude frontal system.

By now the Southern Atlantic Ocean’s second tropical storm in recorded history is expected to have merged with a cold front and just remain in the history books.

The TRMM satellite data was used to create a 3-D image of 90Q. The image showed some fairly high thunderstorm tops near the center of the storm reaching to heights above 12.5 km (over 41,010 feet).
