NASA sees formation of Tropical Storm Fernanda in Eastern Pacific Ocean

13.07.2017

The sixth tropical depression of the Eastern Pacific Ocean hurricane season formed near southwestern Mexico and quickly strengthened into Tropical Storm Fernanda. NASA's Aqua satellite provided infrared imagery of the strengthening storm.

Tropical Depression 6E formed on July 11 at 11 p.m. EDT (July 12 at 0300 UTC) about 740 miles (1,190 km) south of the southern tip of Baja California, Mexico.


This infrared image of Tropical Depression 6E, later named Fernanda, was taken on July 12 at 5:17 a.m. EDT (0917 UTC) just to the south of southwestern Mexico. The purple areas indicate coldest cloud tops and strongest storms.

Infrared satellite imagery from the Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite taken on July 12 at 5:17 a.m. EDT (0917 UTC) provided a look at the temperatures of Tropical Depression 6E's clouds. That data was false colored and made into an image at NASA's Jet Propulsion Laboratory in Pasadena, California to highlight cloud top temperatures.

In infrared imagery, the coldest cloud tops indicate towering thunderstorms high into the troposphere. The colder the clouds, the stronger the storms.

AIRS data showed that some cloud tops around the center of circulation were as cold as minus 63 degrees Fahrenheit or minus 53 degrees Celsius. Cloud top temperatures that cold have been shown to generate heavy rainfall.

Less than six hours later, by 11 a.m. EDT (1500 UTC) on July 12, the National Hurricane Center (NHC) in Miami noted the depression strengthened into a tropical storm.

At that time, the center of Tropical Storm Fernanda was located near 12.0 degrees north latitude and 111.5 degrees west longitude. That's about 760 miles (1,225 km) south of the southern tip of Baja California, Mexico.

Fernanda was moving toward the west near 10 mph (17 kph) and the NHC expects this motion to continue with some increase in forward speed during the next couple of days. Maximum sustained winds have increased near 40 mph (65 kph) with higher gusts. Additional strengthening is expected during the next 48 hours.

Because Tropical Storm Fernanda is far from land, there are no coastal watches or warnings in effect.

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...
