NASA satellites see changes in weakening Typhoon Mawar

06.06.2012
NASA's Tropical Rainfall Measuring Mission (TRMM) and Aqua satellites are just two in NASA's fleet that have been providing data on the evolving and now devolving tropical cyclone. TRMM provided rainfall and other data, while the AIRS instrument on NASA's Aqua satellite provided cloud temperature and extent.

Typhoon Mawar was weakening when the TRMM satellite saw it during the daytime on June 5, 2012 at 0728 UTC (3:28 a.m. EDT/U.S.). Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that Mawar was producing a very large area of rainfall southeast of Japan.


TRMM data showed Mawar was producing a very large area of rainfall southeast of Japan on June 5, 2012. Most of Mawar's heavy rainfall is revealed by TRMM to be north of the dissipating tropical cyclone's center. The most intense surface rainfall of over 40mm/hr (~1.6 inches) was shown northeast of the center. Much of Mawar's southwestern side was shown becoming rain free. This 3-D image shows that Mawar no longer had an eye wall. Storms near Mawar's center of circulation were reaching to heights of only about 10km (~6.2 miles). The highest storm towers of over 11km (~6.8 miles) were located in a band far to the northwest of Mawar's center.

Most of Mawar's heavy rainfall is revealed by TRMM to be north of the dissipating tropical cyclone's center. The most intense surface rainfall of over 40mm/hr (~1.6 inches) was shown northeast of the center. Much of Mawar's southwestern side was shown becoming rain free.

A 3-D image from TRMM's PR shows that Mawar no longer had an eye wall. Storms near Mawar's center of circulation were reaching to heights of only about 10km (~6.2 miles). The highest storm towers of over 11km (~6.8 miles) were located in a band far to the northwest of Mawar's center.

NASA's Aqua satellite flew over Typhoon Mawar and the Atmospheric Infrared Sounder (AIRS) instrument captured infrared images from the storm on June 4, 5, and 6 as it expanded, strengthened, rained on the Philippines and headed north in the western North Pacific. Strongest thunderstorms where high cloud top temperatures were colder than -63 Fahrenheit (-52 Celsius). AIRS data now shows that Mawar is now becoming extra-tropical and is interacting with a frontal zone located south of Japan.

At 0900 UTC (5 a.m. EDT) on June 6, Mawar's maximum sustained winds were down to 65 knots (75 mph/120.4 kph). It was located near 28.1 North and 133.5 East, about 110 nautical miles (126.6 miles/ 203.7 kph) north-northeast of Minamidaito, Japan. Mawar is moving northeast at 23 knots (26.4 mph/42.6 kph).

Mawar is expected to stay to the east of Japan and move between the big island and Chichi Jima and Iwo Two. It should continue tracking east-northeast while weakening.

The system is expected to complete extra-tropical transitioning sometime on June 6. It is expected to weaken because of wind shear increasing to greater than 40 knots (46 mph/84 kph) and cool sea surface temperatures, colder than 23 Celsius (73.4F). Sea surface temperatures of 26.6 C (80F) are needed to maintain a tropical cyclone. As Mawar continues moving east-northeast, Japan's big island will likely experience rough surf along east-facing shores.

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...
