NASA Spots Very Heavy Rainfall Rates in Tropical Cyclone Edilson

10.02.2014
Imagine receiving as much as 7 inches of rain in one hour. That's about what NASA's TRMM satellite spotted falling in one area within Tropical Cyclone Edilson as it moved over the Southern Indian Ocean.

The Tropical Rainfall Measuring Mission or TRMM satellite is managed by both NASA and the Japan Aerospace Exploration Agency called JAXA. TRMM can read the rate in which rain is falling on Earth while in its orbit high above.


TRMM rainfall data on Feb. 7, 2014 showed Edilson south of La Reunion and Mauritius Islands dropping its heaviest rain at a rate of over 175mm/~6.9 inches per hour (red).

The TRMM satellite had an excellent early morning look at Edilson on February 7, 2014 at 0237 UTC/06:28 local time when it passed directly above the tropical cyclone. A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments was overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) at NASA's Goddard Space Flight Center in Greenbelt, Md. to create a total picture of the storm.

Rainfall data showed Edilson south of La Reunion and Mauritius Islands dropping its heaviest rain at a rate of over 175mm/~6.9 inches per hour in an intense feeder band on the eastern side of the tropical cyclone.

TRMM's PR data sliced through Edilson providing data for a 3-D look inside the tropical cyclone. Those data revealed that the highest thunderstorm tops, reaching heights over 14.75km/~9.1 miles were also located in the feeder band east of Edilson's center of circulation.

At 1500 UTC/10 a.m. EST on February 7, the Joint Typhoon Warning Center or JTWC noted that Edilson was located near 29.7 south and 53.9 east, about 508 nautical miles/584.6 miles/940.8 km south of Saint Denis. Edilson's maximum sustained winds were near 50 knots/57 mph/92.6 kph. The tropical storm is moving to the south-southwest at 16 knots/18.4 mph/29.6 kph.

Since the TRMM satellite passed over Edilson, the strongest thunderstorms have weakened as convection has decayed. That's because Edilson is now located within an upper-level shortwave trough (elongated area of low pressure) and is being battered with strong northerly vertical wind shear between 20 and 30 knots/23.0 to 34.5 mph/37.0 to 55.5 kph).

Edilson is expected to continue on a southerly track over the next several days as it becomes extra-tropical over open waters of the Southern Indian Ocean.

Im Focus: Energy-autonomous and wireless monitoring protects marine gearboxes

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...

The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe. 

Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
