NASA's GPM measures meandering Tropical Depression Ida's precipitation

28.09.2015

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).


On Sept. 24, NASA/JAXA's GPM satellite saw some storms in Ida were dropping heavy rainfall at a rate of 122 mm (4.8 inches) per hour. Some storm tops reache 15 kilometers (9.3 miles).

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.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
