NASA sees Tropical Storm Andres fading RapidScat of Andres

05.06.2015

NASA's RapidScat instrument and NASA's Aqua satellite provided a look Tropical Storm Andres' fading winds and rain as it weakens toward dissipation in the Eastern Pacific Ocean. The National Hurricane Center expects Andres to become post-tropical by the end of June 4.

The International Space Station (ISS)-RapidScat instrument measures surface winds over the ocean. The ISS-RapidScat instrument gathered surface wind data on Tuesday, June 4 from 01:53 to 3:25 UTC (June 3 from 9:53 p.m. EDT to 11:25 p.m. EDT).


Early on June 4, RapidScat identified the strongest winds (red) in Andres were in a small area northwest of the center and as strong 25 m/s (55.9 mph/90 kph).

RapidScat identified the strongest winds in Andres were in a small area northwest of the center and as strong 25 meters per second (mps)/55.9 mph/90 kph. Winds surrounding the rest of the center were no stronger than 17 mps/38 mph/61 kph. At 11 a.m. EDT those tropical storm force winds extended outward up to 125 miles (205 km) from the center, according to the National Hurricane Center.

The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite measured cloud top temperatures in Andres on June 4 at 10:11 UTC (6:11 a.m. EDT). Infrared data shows temperature, and the higher the thunderstorms and more powerful, the colder the cloud tops.

Andres cloud top temperatures had warmed, and the only thunderstorms seen in the system were pushed northeast of the center by vertical wind shear. The NHC discussion on June 4 at 11 a.m. EDT, stated that "The mid-level center of the cyclone appears to have decoupled from the low-level circulation about 12 hours ago, and only a small area of deep convection remains nearly two degrees removed from the center."

Although Andres is weakening, it is still generating ocean swells felt along portions of the west coast of the Baja California peninsula. The National Hurricane Center (NHC) expects those swells to begin diminishing late on Thursday and Friday, June 5.

NHC noted that at 11 a.m. EDT (1500 UTC) the center of Tropical Storm Andres was located near latitude 20.1 North, longitude 124.5 West. The estimated minimum central pressure is 1003 millibars (29.62 inches). Andres was moving toward the east at 3 mph (6 kph), and a turn toward the east-southeast or southeast is expected during the next 24 hours. Maximum sustained winds had decreased to near 40 mph (65 kph) with higher gusts.

Two factors are weakening Tropical Storm Andres: strong west-southwesterly shear and cool waters. Global computer forecast models show the circulation of Andres degenerating into an open trough (elongated area of low pressure) within two to three days.

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...
