NASA has Tropical Storm Dolly covered by satellite and the remotely piloted Global Hawk aircraft. Both captured data on Dolly before it made landfall in eastern Mexico.
The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite took an image of Tropical Storms Norbert in the Eastern Pacific and Dolly in the Gulf of Mexico at 1:30 p.m. EDT on Sept. 2. The image showed Dolly is a much more organized storm than Norbert, and revealed Dolly's strongest, towering thunderstorms around the center of circulation. Norbert is close to the western coast of Mexico, so the country has tropical storms to the east and west. The image was created by the NASA MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
At 11 p.m. EDT on September 2, Dolly made landfall between Tampico and Cabo Rojo, near latitude 21.9 north and longitude 97.7 west.
One of NASA's unmanned Global Hawk aircraft number 872 surveyed Tropical Storm Dolly during the night-time hours of September 2 as part of NASA's latest hurricane airborne mission known as the Hurricane and Severe Storm Sentinel, or HS3 mission.
"We saw winds at low levels (near 850 millibars) up to about 35 to 40 knots (40 to 46 mph) and a reasonably depicted cyclonic circulation," said HS3 Principal Investigator, Dr. Scott Braun of NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The data at 150 millibars (high in the atmosphere) shows the strong outflow from the storm to the east and southeast."
In the image, the dropsonde data gathered from NASA's Global Hawk were adjusted over the satellite image of the storm to compensate for the storm's movement. As a result, although the image makes dropsonde data look as if it were over eastern Mexico, there were no drops over the country. The data was just shifted to match the satellite image. All dropsondes were dropped over the Gulf of Mexico.
NASA's HS3 mission returned to NASA Wallops Flight Facility, Wallops Island, Virginia for the third year to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. HS3 is a collaborative effort that brings together several NASA centers with federal and university partners.
By 8 a.m. EDT (1200 UTC) on September 3, Dolly had weakened to a depression with maximum sustained winds near 35 mph (55 kph). The National Hurricane Center (NHC) expects Dolly to weaken quickly and dissipate by the end of the day on September 3. Dolly was centered near latitude 21.7 north and longitude 98.8 west, about 65 miles (110 km) west-southwest of Tampico, Mexico. Dolly was moving toward the west near 8 mph (13 kph) and is expected to continue in that direction for the next day or so taking Dolly farther inland.
As with any tropical cyclone that makes landfall, heavy rainfall is always a concern. The NHC expects Dolly to produce rainfall amounts of 5 to 10 inches with isolated maximum amounts of 15 inches across much of Tamaulipas and Nuevo Leon...as well as northern Veracruz and eastern San Luis Potosi, Mexico through Wednesday evening. This rainfall is expected to cause life-threatening flash floods and mud slides in areas of mountainous terrain.

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...
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....
