Satellite technology has the ability to see things we could never imagine, like how hard the rain is falling in storms, and how high cloud tops stretch into the atmosphere.
The Global Precipitation Measurement (GPM) core observatory satellite does both of those things and has been providing that information each time it passes over Typhoon Halola in the Northwestern Pacific Ocean.
The GPM core observatory is a joint effort between NASA and the Japan Aerospace Exploration Agency. GPM saw Halola when it was strengthening from a tropical storm into a typhoon. GPM flew over Tropical Storm Halola on July 20, 2015 at 0351 UTC (July 19 at 11:51 p.m. EDT).
Then on July 21, 2015 at 1425 UTC (10:25 a.m. EDT) GPM saw Halola again as a typhoon. GPM saw the rate in which rain was falling within the storm using GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instrument (DPR). Those instruments revealed that the heaviest rain was falling at a rate of over 84 mm (3.3 inches) per hour.
At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a simulated 3-D view of the storm was created using Ku band radar data. That 3-D view showed that the tall thunderstorm towers in Halola's eye wall had reached heights of over 17km (10.5 miles). These tall thunderstorms near the center of a typhoon release energy that can result in intensification.
Today, July 23 at 11 a.m. EDT, Halola's maximum sustained winds dropped to 85 knots (97.8 mph/157.4 kph) from 90 knots (103.6 mph/166.7 kph) just six hours It was centered near 24.7 North latitude and 133.8 East longitude, about 370 nautical miles (426 miles/685.7 km) east-southeast of Kadena Air Base, Okinawa, Japan. Halola was moving to the west-northwest at 7 knots (8 mph/12.9 kph).
Halola is now expected to track just west of the island of Kyushu on July 26 and curve to the northwest through the Sea of Japan.

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...
