NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission or TRMM satellite passed over a dissipating former Hurricane Cristina and found it still contained heavy rain as it rapidly weakened.
Hurricane Cristina had sustained winds of over 130 knots (almost 150 mph) on June 12, 2014 making her the second hurricane in the eastern Pacific Ocean this year to reach category four on the Saffir-Simpson hurricane wind scale.
The TRMM satellite had an excellent view of Cristina when it flew over on June 14, 2014 at 1031 UTC (6:31 a.m. EDT). At that time, Cristina had started weakening and had wind speeds estimated at less than 70 knots (about 80 mph) when TRMM flew overhead.
To form a complete picture of the storm, rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments were overlaid on an enhanced infrared image of Cristina's clouds taken from NOAA's GOES-West satellite. The images were combined at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Although Cristina had started a weakening trend TRMM's Precipitation Radar instrument still found rain falling at a rate of almost 97 mm (about 3.8 inches) per hour in the northwestern side of Cristina's eye wall. At Goddard, TRMM's PR data was used to create a 3-D view of the Cristina's rainfall structure.
That 3-D image showed powerful thunderstorms in the northwestern side of the storm were reaching heights above 13.5 km (about 8.4 miles). These same TRMM data showed that Cristina's eye wall was broken on the eastern side.
The passage of Cristina over cooler ocean waters and southwesterly wind shear resulted in the once powerful hurricane dissipating to a remnant low pressure area on Sunday, June 15, 2014.
On June 17 at 09:02 a.m. EDT, the National Hurricane Center (NHC) noted that the remnant low pressure center of Cristina continued to spin in the Eastern Pacific, and the circulation center was located near 23 north latitude and 117 west longitude.
NHC forecasters noted that the circulation will continue to spin down over the next couple of days and is expected to dissipate by the night time hours on Wednesday, June 18.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
