GOES-13 on top of new seventeenth Atlantic (sub) tropical depression

07.10.2010
The GOES-13 satellite keeps a vigilant eye on the Atlantic Ocean and eastern U.S. and this morning at 5 a.m. EDT it saw System 97L organize into the seventeenth tropical depression of the Atlantic Ocean season. The only catch is that it is actually a subtropical depression, so it is currently known as Subtropical Depression 17 (TD17).

A subtropical storm is one where central convection (rapidly rising air that forms thunderstorms) is fairly near the center and it has a warming core in the mid-levels of the troposphere. Subtropical cyclones differ from tropical cyclones because they have broad wind patterns and their maximum sustained winds are located farther from the center of the system than tropical cyclones.


GOES-13 (The Geostationary Operational Environmental Satellite) visible image of Subtropical Depression 17 (top, center) at 1145 UTC (7:45 a.m. EDT) shows a tight circulation and a long \"tail\" of clouds and showers that extend to the southeast of the center, reaching the northern Leeward Islands and Puerto Rico.

In addition, they usually have colder temperatures in upper levels of the atmosphere than tropical cyclones (which have very warm cores). Finally, sea surface temperatures required for the formation of sub-tropical storms are about 5 degrees Fahrenheit cooler than needed for a tropical cyclone to develop (80 F).

TD17 is forecast by the National Hurricane Center to move into a more favorable environment to develop, and its core may warm up making it into a tropical depression or tropical storm, if it intensifies.

The Geostationary Operational Environmental Satellite called GOES-13 captured an infrared image of TD17 on October 6 at 1231 UTC (8:31 a.m. EDT). GOES satellites are managed by NOAA. NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. creates images and animations from the satellite data and created today's image that shows TD17 has a tight circulation and a long "tail" of clouds and showers that extend to the southeast of the center, reaching the northern Leeward Islands and Puerto Rico.

At 5 a.m. EDT on Oct. 6, TD17's maximum sustained winds were 35 mph. It was located about 270 miles north-northwest of San Juan, Puerto Rico and 710 miles south of Bermuda near 22.2 North and 67.0 West. It was moving northwest at 8 mph with minimum central pressure of 1001 millibars. TD17's "tail" extends to the southeast from the center of the system, and may bring some heavy rainfall in the northern Leeward Islands and Puerto Rico over the next day as it moves northwest then turns northeast to head out to the open waters of the Atlantic.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
