NASA sees Tropical Cyclone Linda lose an 'arm'

14.03.2018

Tropical Cyclone 13P has been renamed Tropical Cyclone Linda in the Southern Pacific Ocean. NASA's Aqua and Terra satellites found a powerful band of thunderstorms east of Linda's center that resembled an arm, fell apart in 9 hours.

By analyzing a storm in infrared light, scientists can tell cloud top temperatures that give clues about the location of the highest, coldest and strongest storms.


On March 13, 2018, at 8:30 a.m. EDT (1230 UTC) NASA's Terra satellite found top temperatures of strongest thunderstorms (yellow) in Tropical Cyclone Linda. Temperatures were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius).

On March 12 at 11:05 p.m. EDT (March 13 at 0305 UTC), infrared data from the Atmospheric Infrared Sounder, or AIRS, instrument aboard NASA's Aqua satellite found the strongest storms in Linda. AIRS data showed powerful storms around Linda's center and in a strong band of thunderstorms east of the center.

By 8:30 a.m. EDT (1230 UTC) the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument aboard NASA's Terra satellite provided an infrared look at Tropical Storm Linda's cloud top temperatures. The MODIS image showed that the once-strong band of thunderstorms east of Linda's center had weakened and fragmented.

MODIS data also found cloud top temperatures of strongest thunderstorms were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 Celsius) around the center of circulation. The center was located over the open waters of the South Pacific. Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.

The Joint Typhoon Warning Center noted on March 13 at 11 a.m. EDT (1500 UTC) when the center was located near 21.1 degrees south latitude and 158.9 degrees east longitude, about 397 nautical miles west-northwest of Noumea, New Caledonia. Linda had maximum sustained winds near 46 mph (40 knots/74 kph) and it was moving to the south-southwest at 19.5 mph (17 knots/31.4 kph).

The Joint Typhoon Warning Center noted that Linda is being affected by northerly vertical wind shear, pushing clouds south of center. Linda is moving south-southwest along the western edge of subtropical ridge (an elongated area of high pressure), which is located to the east-southeast of the tropical storm.

Linda is expected to continue moving under increasing adverse conditions, so the storm is expected to dissipate by March 15.

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....
