NASA Satellite Sees a Somewhat Lopsided Typhoon Halong

05.08.2014

Infrared satellite imagery from NASA shows bands of powerful thunderstorms around Typhoon Halong's center, southern and eastern quadrants, while the northern quadrant is lacking in them. Typhoon Halong appears somewhat lopsided on satellite imagery because thunderstorm development in the northern side of the storm is being inhibited.

When NASA's Aqua satellite passed over Typhoon Halong on Aug. 4 at 12:47 a.m. EDT, the Atmospheric Infrared Sounder (AIRS) instrument aboard provided infrared data on the cloud top temperatures of Typhoon Halong.


On Aug. 5 at 02:15 UTC, the MODIS instrument aboard NASA's Terra satellite captured this visible image of Typhoon Halong in the western Pacific Ocean.

AIRS data showed powerful thunderstorms with the highest, coldest cloud tops circled the center of the storm and were in two thick bands in the southern and eastern quadrants of the storm. Cloud top temperatures exceeded -63F/-52C indicating they were nearing the top of the troposphere.

NASA research has shown that cloud top temperatures that cold, from storms that high, have the potential to produce heavy rainfall.

The other thing that the infrared imagery showed was a degradation of strong convection and thunderstorm development in the northern half of the storm. The Joint Typhoon Warning Center noted that development is being inhibited because of subsidence, that is, the sinking of air (from above).

In order for thunderstorms to form, air needs to rise and condense into clouds. When air is sinking from overhead, it prevents cloud formation from happening.

On Aug. 5 at 02:15 UTC, the MODIS instrument aboard NASA's Terra satellite captured a visible image of Typhoon Halong in the western Pacific Ocean that showed the strongest bands of thunderstorms continued to be in the southern and eastern quadrants of the storm.

At 1500 UTC (11 a.m. EDT) Halong's center was located near 21.4 north latitude and 130.1 east longitude, about 351 nautical miles (403.9 miles/ 650.1 km) south-southeast of Kadena Air Base, Okinawa. Maximum sustained winds were near 85 knots (97.8 mph/157.4 kph).

Halong continues to generate extremely rough seas with maximum significant wave heights at 35 feet (10.6 meters).

JTWC forecasters expect Halong to continue moving north-northeast over the next day or two before taking a more northerly track toward mainland Japan.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
