NASA's Terra Satellite Sees Typhoon Nuri in Eyewall Replacement

05.11.2014

High clouds had moved over Super Typhoon Nuri's eye early on Nov. 4 when NASA's Terra satellite passed overhead as the storm was undergoing eyewall replacement.

Eyewall replacement occurs when the thunderstorms that circle the eye of a powerful typhoons or hurricanes are replaced by other thunderstorms. Basically, a new eye begins to develop around the old eye. Many intense hurricanes undergo at least one of these eyewall replacements during their existence.


On Nov. 4 at 01:55 UTC (8:55 p.m. ET) NASA's Terra satellite captured this image of Super Typhoon Nuri as clouds moved into its eye.

On Nov. 4 at 01:55 UTC (8:55 p.m. EST) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite captured a visible image of Super Typhoon Nuri as clouds moved into its eye.

The MODIS image showed a large, thick band of thunderstorms spiraling into the eye that stretched to the south of the center. The extent of the clouds in the northern quadrant appeared to be just east of Japan.

A microwave image from NASA/JAXA's Tropical Rainfall Measuring Mission showed that Nuri is undergoing eyewall replacement, although the previously observed eye feature has become cloud filled and less defined.

By 1500 UTC (10 a.m. EST), Nuri's maximum sustained winds had dropped to 120 knots (138.1 mph/222.2 kph). Nuri was centered near 23.5 north latitude and 136.6 east longitude, about 293 nautical miles (337.2 miles/542.6 km) west-southwest of Iwo To and has tracked northeastward at 12 knots (13.8 mph/22.2 kph).

NOAA's National Weather Service office on Iwo To (also known as Iwojima) current conditions at 10 a.m. EST on Nov. 4 reported winds from the southeast were sustained at 22 mph. Skies were mostly cloudy and the air temperature was 78F (26C). Heavy rain showers were reported on Nov. 3.

Nuri is passing to the west of Iwo To and is expected to move to the northeast and parallel the big island of Japan over the next couple of days while weakening. Within two days the storm is expected to weaken just below hurricane-force.

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...
