NASA Sees Strength in Newborn Tropical Cyclone Emang

15.01.2013
Tropical Cyclone Emang developed in the Southern Indian Ocean on Sunday, Jan. 13 about 525 nautical miles east-southeast of Diego Garcia. At that time, infrared satellite imagery revealed that the low level circulation center was partially exposed to outer winds, and there was a burst of thunderstorm development over the northwestern quadrant.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured rainfall rates in Tropical Storm Narelle on Jan. 13 at 0907 UTC (5:07 a.m. EST). Moderate and heavy rainfall was occurring around the center of circulation, where rainfall rates ranged from 30 mm (1.18 inches) to 50 mm (2 inches) per hour. That heavy rainfall is a sign that there is strong convection occurring within the storm, and forecasters at the Joint Typhoon Warning Center expect the storm will consolidate and organize more over the coming week.

On Monday, Jan. 14, at 0900 UTC (4 a.m. EST), Emang's maximum sustained winds were near 35 knots (40 mph/64.8 kph). Emang's center moved near 12.5 south latitude and 79.4 east longitude, about 500 nautical miles (575.4 miles/ 926 km) southeast of Diego Garcia. Emang was moving to the southwest at just 3 knots (3.4 mph/5.5 kph). Emang is located in is a weak steering environment. It is moving slowly under the influence of a building subtropical ridge (elongated area) of high pressure located to the south of the storm.

Monday's satellite data showed that the low-level center had now become fully exposed to outside winds, and there were shallow bands of thunderstorms around the northwestern edge of the storm. Emang is currently being battered with moderate (up to 20 knots/23 mph/37 kph) vertical wind shear.

Forecasters at the Joint Typhoon Warning Center expect improvements in environmental conditions which will improve the storm's organization. Emang is expected to slowly intensify over the next couple of days as it travels over open ocean. By the end of the week, Emang is expected to reach peak intensity as a cyclone of 65 knots (74.8 mph/120.4 kph).

Emang is currently not a threat to any land areas.

Im Focus: Breaking: the first light from two neutron stars merging

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....

Im Focus: Smart sensors for efficient processes

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...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...

Im Focus: New nanomaterial can extract hydrogen fuel from seawater

Hybrid material converts more sunlight and can weather seawater's harsh conditions

It's possible to produce hydrogen to power fuel cells by extracting the gas from seawater, but the electricity required to do it makes the process costly. UCF...
