The Global Precipitation Measurement or GPM core observatory satellite had another good view of meandering tropical storm Ida located in the central Atlantic Ocean and measured rainfall rates within the storm.
GPM is a satellite jointly managed by NASA and the Japan Aerospace Exploration Agency. GPM passed over Ida on September 24, 2015 at 0756 UTC (3:35 AM EDT).
Measurements of precipitation by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Ida still contained a few embedded strong convective thunderstorms that were dropping heavy rainfall. Some rainfall was measured by GPM's Ku Band radar falling at a rate of 122 mm (4.8 inches) per hour.
GPM's 3-D radar reflectivity data (DPR Ku band) can be used to reveal the intensity of rain showers embedded within a tropical cyclone. Measurements of Ida, a tropical storm at the time GPM passed overhead, showed that isolated thunderstorms had storm tops reaching heights of 15 kilometers (9.3 miles) and intense rain showers.
At 5 a.m. EDT (0900 UTC), the center of Tropical Depression Ida was located near latitude 21.7 North, longitude 45.3 West. That's about 1,180 miles (1,900 km) east-northeast of the Northern Leeward Islands
Ida was moving toward the north-northwest near 3 mph (6 kph), and Ida is expected to turn to the northwest late on September 25. The estimated minimum central pressure is 1007 millibars.
Maximum sustained winds are near 35 mph (55 kph) and the National Hurricane Center expects some weakening over the next two days. Ida is expected to become a remnant low over the weekend.

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....
