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: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
