TRMM Eyes Rainfall in Dissipating Former Hurricane Cristina

18.06.2014

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.


On June 14, NASA's TRMM satellite 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 where thunderstorms reached above 13.5 km (about 8.4 miles).

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.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
