When NASA's Aqua satellite passed over Typhoon Soulik on July 11 an instrument aboard noticed clouds filled the eye and additional data showed the eyewall was being replaced.
The TRMM satellite flew over Soulik on July 10 at 14:06 UTC and saw a well-defined eye and multiple intense (red) and moderate and weak (green, blue) that wrapped tightly around the eye.

On July 11 at 04:20 UTC (12:20 a.m. EDT), NASA's Aqua satellite flew over Typhoon Soulik in the western Pacific Ocean. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument saw that Soulik's eye had become cloud-filled and the storm's maximum sustained winds had dropped since the previous day. However, satellite data indicates the eye is reforming.
The Joint Typhoon Warning Center forecasters use multi-spectral satellite imagery when assessing a tropical cyclone and noted that imagery showed multiple bands of thunderstorms wrapping around Soulik's center, and the ragged cloud-filled eye was still 20 nautical miles (23 miles/37 km) in diameter. Microwave satellite imagery confirmed the reforming eye, and showed that those strong bands of thunderstorms were wrapping around the southern side of the storm.
Soulik Reached Super Typhoon Status
It was just yesterday, July 10 at 0000 UTC (July 9 at 8 p.m. EDT) that Typhoon Soulik became the first super typhoon of the year when the Joint Typhoon Warning Center estimated that it's sustained winds had increased to 125 knots (~144 mph), which is equivalent to a Category 4 hurricane on the U.S. Saffir-Simpson scale.
NASA's TRMM Satellite
NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission or TRMM satellite flew over Soulik on July 10 at 14:06 UTC (10:06 a.m. EDT) and measured rainfall rates occurring within the storm. TRMM data showed that Soulik had all of the features of a powerful, mature tropical cyclone, including a well-defined eye and multiple intense rain bands (red, green and blue areas indicating intense, moderate and weak rain intensity, respectively) that wrap tightly around the eye, which reflect the storm's strong cyclonic circulation.Soulik's Status
Soulik is still moving in a westerly direction through the northwestern Pacific Ocean and at a speed of 12 knots. Typhoon Soulik was located near latitude 22.4 north and longitude 129.1 east, about 273 nautical miles (314 miles/505 km) south-southeast of Kadena Air Base. Soulik's powerful winds were stirring up maximum wave heights near 38 feet (11.5 meters).
According to the Joint Typhoon Warning Center, Typhoon Soulik is forecast to move just south of Japan's Ishigaki-jima Island early on July 12, and brush the northern end of Taiwan later in the day as it heads to China for landfall on July 13.

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...
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...
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...
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....
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...
