Typhoon Melor and Tropical Storm Parma mean double trouble in the western Pacific

09.10.2009
1 NASA satellite gets 2 storms in 1 image

There's double-trouble in the Western Pacific with one typhoon and one tropical storm bringing soaking rains, dangerous surf and gusty winds to two different locations. Typhoon Melor is affecting the east coast of Japan and watches and warnings are up today. Further south, Tropical Storm Parma continues to rain on Luzon in the northern Philippines.

Typhoon Melor is currently affecting southern Japan and bringing gusty winds, heavy rains and high waves there. High Wave and Gale Watches and warnings have been posted in Japan in the prefectures of Miyazaki and Kagoshima today.

At 11 a.m. EDT, Typhoon Melor had sustained winds near 75 knots (86 mph). It was located 350 nautical miles southwest of Tokyo, Japan, near 32.7 North and 135.4 East. Melor is moving northeast near 25 knots (28 mph) and is generating 30-foot high waves. At 11 a.m. EDT, the storm was almost due south of the city of Wakayama.

Melor is currently becoming extra-tropical as it approaches Honshu. It will accelerate northeast to the west of Tokyo and reemerge over the Pacific as a strong non-tropical low pressure system.

At 11 a.m. EDT on October 7, Parma had been downgraded to a tropical storm with sustained winds near 35 knots (42 mph). Parma was located 225 nautical miles north-northeast of Manila, Philippines, near 18.1 North and 122.4 East. Parma has tracked north-northeastward at 4 mph. Parma is still generating waves up to 22 feet high.

Parma's forecast track is still somewhat questionable, as different computer forecast models take Parma on different tracks. However, forecasters at the U.S. Navy's Joint Typhoon Warning Center are forecasting Parma to slowly crawl from northeastern Luzon back across the northern island and finally into the South China Sea sometime on October 9. The slow movement across the northern Philippines means more unwelcome rain in the region over the next several days.

Warnings are posted in the Philippines today. Public storm warning signal 1 is in force in Batanes Group of Islands, Cagayan, Babuyan Island, Calayan Island, Ilocos Norte & Sur, Apayao, Abra, Kalinga, Mountain Province, Isabela, Ifugao, Nueva Vizcaya, Northern Aurora and Benguet.

An instrument on NASA's Aqua satellite captured both typhoons in one image. The Atmospheric Infrared Sounder (AIRS) captured both Parma and Melor in a visible and infrared image October 7 at 0453 UTC (12:53 a.m. EDT) as Parma continues to rain on northern Luzon in the Philippines, while Melor is now bringing rains and winds over southern Japan.

The infrared imagery revealed that the cloud tops of Parma are not as cold as they are in Melor, indicating that Parma is a much weaker storm. Typhoon Melor has some strong thunderstorms, where temperatures are colder than -63 Fahrenheit.

Infrared imagery has also shown that Tropical Storm Parma has made its track over Luzon, and is now back over the open waters of the Philippine Sea. Although Parma's track over land weakened the storm, the open waters are expected to power the storm's convection and thunderstorms back up. In fact, infrared imagery has shown that convection is already redeveloping near the low level center of the storm.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
