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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
