NASA's Aqua satellite sees Tropical Storm Ana still affecting Hawaii

22.10.2014

Slow-moving Tropical Storm Ana was still affecting parts of Hawaii on Oct. 20 when NASA's Aqua satellite passed overhead from its orbit in space. Imagery from Aqua showed that wind shear was affecting the storm.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible picture of Tropical Storm Ana over Hawaii on Oct. 20 at 23:55 UTC (7:55 p.m. EDT). The image showed that most of the clouds and showers were north and east of the center of circulation, pushed away from the center by strong southwesterly wind shear.

The MODIS image showed clouds in Ana's eastern quadrant covered the islands of Kauai and Niihau. Kauai is geologically the oldest of the main Hawaiian Islands and fourth largest of the main islands in the Hawaiian archipelago. Niʻihau or Niihau is the seventh largest of the inhabited Hawaiian Islands.

A tropical storm warning is still in effect for parts of the Papahanaumokuakea Marine National Monument from Nihoa to Maro Reef. The Central Pacific Hurricane Center (CPHC) noted that rainfall totals of 4 to 8, locally up to 12, inches are possible over the northwestern Hawaiian Islands near the center of the storm.

At 8 a.m. EDT (2 a.m. HST/1200 UTC) Ana's maximum sustained winds were near 50 mph (85 kph) and little change in strength is forecast through early Thursday. The center of tropical storm Ana was located near latitude 20.8 north and longitude 165.4 west. Ana's center was about 215 miles (345 km) south-southeast of French Frigate Shoals. The French Frigate Shoals is the largest atoll in the Northwestern Hawaiian Islands.

Ana was moving toward the west near 9 mph (14 kph) but the storm is expected to gradually become northerly through early Thursday, Oct. 22. The estimated minimum central pressure is 999 millibars.

CPHC warnings cited large swells produced by Ana will build across the northwest Hawaiian Islands through Wednesday. Surf produced by these swells will be dangerous along the southern and southeastern facing reefs of the northwest Hawaiian Islands.

The CPHC expects Ana to curve to the northeast and start transitioning into an extra-tropical storm on Friday, Oct. 24.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

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....
