NASA looks at winds, cloud extent of Patricia's remnant hybrid system

28.10.2015

NASA's RapidScat analyzed the winds in the Gulf of Mexico that were associated with the hybrid storm the included the remnants of former Eastern Pacific Ocean Hurricane Patricia. NOAA's GOES-East satellite showed the extent of the hybrid system's cloud cover over the southeastern U.S. on October 27.

Patricia's remnants merged with an upper-level low pressure area after it made landfall, and that system has plagued the U.S. Gulf coast states with heavy rains and gusty winds since Sunday, Oct. 25.

NASA's RapidScat instrument flies aboard the International Space Station and can detect the speed and direction of surface winds over open waters. "On October 26 at 1500 UTC (11 a.m. EDT) RapidScat got another view of the Gulf of Mexico which showed moderately high winds over a very broad area as well as a low pressure area centered over Louisiana," said Doug Tyler of the RapidScat team at NASA's Jet Propulsion Laboratory, Pasadena, California.

RapidScat saw a small area of strongest winds over the Gulf of Mexico, just south of the Florida Panhandle at 27 meters per second (60.4 mph/97.2 kph). Near the center of the low pressure area, RapidScat measured a large area of sustained winds near 18 meters per second (40 mph/64 kph) over the Gulf of Mexico, and just south of Louisiana.

On October 27, the National Weather Service discussion said "The area of low pressure that brought heavy rain to the Gulf Coast will begin moving northward on Tuesday, bringing rain to the Ohio Valley and Appalachians before moving toward the Northeast on Wednesday. Rainfall amounts will generally be less than those across the southern Plains and Gulf Coast over the past few days."

A visible image of the clouds associated with Patricia-hybrid system were seen in a visible image from NOAA's GOES-East satellite on October 27, 2015 at 1630 UTC (12:30 p.m. EDT). Clouds associated with the system stretch from Florida west to Louisiana and over the Mississippi and Tennessee Valleys north to the Mid-Atlantic States. NOAA manages the GOES series of satellites, and NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland creates images and animations using the satellite data.

At 10 a.m. EDT the surface low with a central pressure of 1006 millibars was located about 60 miles northwest of New Orleans, Louisiana. The National Weather Service explained that an occluded front extended from the low pressure center and was moving north through southern Mississippi and Alabama. Also, there was a cold front extending from the east-central Gulf of Mexico and a quasi-stationary frontal boundary that stretched across the Alabama/Florida border and Georgia/Florida border and into the western Atlantic Ocean

The GOES image showed the clouds associated with the tropical moisture that continued to stream into the southeastern states ahead of an upper level system located in the Deep South. For forecast updates, visit the National Weather Service: http://www.weather.gov.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
