NASA Sees Tropical Storm Rumbia Hit China With Heavy Rainfall

03.07.2013
Typhoon Rumbia had weakened to a tropical storm and moved over southern China when NASA’s TRMM satellite flew above on July 2, 2013 at 0316 UTC and measured its rainfall rates.

An analysis of rainfall from TRMM Microwave Imager (TMI) and Precipitation (PR) data shows that Rumbia was dropping rain at a rate of over 92mm/hour (~3.6 inches) in areas of southern China near the Gulf of Tonkin. An intense but narrow feeder band near Hong Kong is shown streaming heavy rainfall into China from the South China Sea.

An image showing a 3-D slice through of tropical storm Rumbia was created at NASA’s Goddard Space Flight Center in Greenbelt, Md. using TRMM Precipitation Radar data. Those data showed that the thunderstorms near Rumbia's center of circulation were then reaching heights mainly below 13 km (~8.1 miles). Some powerful thunderstorms in the feeder band near Hong Kong were found to reach to heights of 15 km (~9.3 miles).

Just before TRMM flew overhead, Tropical storm Rumba had made landfall over southeastern China on July 2, 2013 at 0300 UTC (July 1 at 11 p.m. EDT). The storm was 231 miles east of Hanoi, Vietnam near 21.4 north and 110.0 east. Rumbia’s maximum sustained winds were near 50 knots (57 mph/92 kph) and dropping.

According to the Joint Typhoon Warning Center, radar imagery from Haikou, China at 0300 UTC (July 1 at 11 p.m. EDT), showed that the tightly-curved banding of thunderstorms became less organized, and had weakened.

On July 2, China’s National Meteorological Centre (NMC) issued a blue category warning of typhoon at 6:00 p.m. (Beijing Time). The blue category warning means strong winds are expected along coastal Guangxi, and Beibu Gulf. Central and western Guangxi and southern Yunnan can expect heavy rainfall and gusty winds. In central Guangxi, there will be isolated areas of heavy rainfall as high as (100-120 mm/4.0 to 4.7 inches).

According to the NMC, “Severe tropical storm Rumbia has weakened into a tropical storm at 12:00 [p.m. local time] today. At 17:00 (5 p.m. local time), it was centered over Laibin city of Guangxi Zhuang Autonomous region (23.4°N, 109.0°E ) with maximum wind force up to scale 8 (18 meters/second) [64 kph/40 mph].”

Rumbia was moving to the northwest at 11 knots (12.6 mph/20 kph) and is expected to dissipate over China in the next day or two.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
