Tropical Storm Maliksi forms, Iwo To on guard

02.10.2012
The western North Pacific is in full swing, tropically speaking and NASA observed the birth of Tropical Storm Maliksi on Sept. 30. NASA's Aqua satellite captured an infrared image of the storm when it was a depression and revealed a large area of powerful thunderstorms around its center that hinted at its strengthening.

Tropical Storm Maliksi formed from the twentieth tropical depression of the western North Pacific typhoon season. Tropical Depression 20W formed on Sept. 20 about 305 nautical miles from Guam near 16.3 North and 149.0 East. It is moving to the north-northwest at 11 knots (12.6 mph/20.3 kph).


This infrared image was created from AIRS data on Oct. 1 at 02:53 UTC (10:53 p.m. EDT, Sept. 30) as Tropical Depression 20W was strengthening into tropical storm Maliksi. Strongest thunderstorms with very cold cloud top temperatures (colder than -63F/-52 C) appear in purple.

On Oct. 1 the depression strengthened into a tropical storm. At 1500 UTC (11 a.m. EDT) it was located near 19.3 North and 145.1 East about 50 nautical miles (57.5 miles/92.6 km) northwest of Pagan, in the Northern Marianas archipelago. It is under the jurisdiction of the Commonwealth of the Northern Mariana Islands. It had maximum sustained winds near 35 knots (40 mph/65 kph). The Marianas Islands are an arc-shaped archipelago. The island chain includes fifteen volcanic mountains.

When NASA's Aqua satellite passed over Tropical Depression 20W in the western North Pacific, it captured an infrared image with the Atmospheric Infrared Sounder (AIRS) instrument on Oct. 1 at 02:53 UTC (10:53 p.m. EDT, Sept. 30). A large area of powerful thunderstorms with very cold cloud top temperatures (colder than -63F/-52 C) surrounded the center of circulation, hinting that the storm was organizing and strengthening. It became a tropical storm hours after the image was taken.

Maliksi has organized during the morning hours of Oct. 1, with strongest convection (rising air that forms thunderstorms) and bands of thunderstorms over the southeastern quadrant. Those bands of thunderstorms, however, have not yet begun wrapping into the low level center, which is an indication that the storm still has a way to go to get fully organized.

Maliksi is expected to pass Iwo To during October 3 and strengthen into a typhoon on its journey to the northeast.

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...
