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: An engineered surface unsticks sticky water droplets

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.

Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...

Im Focus: Increasingly severe disturbances weaken world's temperate forests

Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.

"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...

Im Focus: OU astrophysicist and collaborators find supermassive black holes in quasar nearest Earth

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...

Im Focus: What would a tsunami in the Mediterranean look like?

A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).

Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...

Im Focus: Self-healing landscape: landslides after earthquake

In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.

These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...
