NASA satellite gets 2 tropical cyclones in 1 shot

24.06.2011
The Northwestern Pacific Ocean is active with two tropical cyclones today, Tropical Storm Meari near the Philippines, and Tropical Depression Haima moving over China and now toward Vietnam. NASA's Aqua satellite passed over the region on June 22 and captured an infrared image of both storms in one image.

One of the instruments onboard NASA's Aqua satellite is the Atmospheric Infrared Sounder (AIRS). AIRS captures cloud top temperatures in tropical cyclones to determine the strength of convection and thunderstorms. The strongest thunderstorms have cloud tops with icy cold temperatures of -63F/-52C and are indicative of areas where rainfall rates could reach up to 2 inches / 50 mm per hour and both Meari and Haima had large areas of those very cold cloud top temperatures.

AIRS captured the image on June 22 at 17:53 UTC 1:53 p.m. EDT and it showed the heaviest rainfall and strongest convection (rapidly rising air that forms the thunderstorms that power a tropical cyclone) from Tropical Storm Meari is currently over the Philippine Sea and skirting the east coast of Luzon. The imagery showed the large area of strong thunderstorms (and convection) in Haima mostly over the South China Sea and Hainan Island, China.

Haima is still a tropical depression as its maximum sustained winds on June 23 at 1500 UTC (11 a.m. EDT) were near 30 knots (34 mph/55 kmh). Tropical storms have maximum sustained winds between 38 and 73 mph. It was located over Hainan Island, China, and about 235 nautical miles west-southwest of Hong Kong, China near 21.4 North and 109.6 East. Tropical Depression Haima is moving westward at 10 knots (11 mph/19 kmh).

The Joint Typhoon Warning Center does not expect Haima to strengthen into a tropical storm because of its interaction with land over Hainan Island, and its short track over the South China Sea between there and Vietnam where it is expected to make its final landfall. An orange alert in now in effect for North and South Korea as Tropical Depression Haima is tracking in that direction.

Meari is a tropical storm, and has maximum sustained winds near 40 knots (46 mph/78 kmh). It is centered to the east of Luzon, the Philippines and about 500 nautical miles south-southwest of Kadena Air Base, Japan. Meari is moving to the northwest at 12 knots (14 mph/22 kmh).

The Joint Typhoon Warning Center noted that Meari's center of circulation is elongated and there are "multiple minor vorticies developing and rotating cyclonically around the center." During the morning hours on June 23, AIRS data and microwave satellite data showed that convection has consolidated around the center, helping to better pinpoint the center in this massive storm system.

As Meari continues on a northward track it will run into cooler sea surface temperatures in the Yellow Sea, they will weaken the tropical storm quickly.

Meari's center is forecast now to remain at sea and brush Taiwan, eastern China and make landfall in the southwestern area of North Korea this weekend.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
