Tropical Depression 11W moving past Yap and Guam

28.07.2011
A NASA satellite has observed Tropical Depression 11W become more organized on infrared imagery. Fortunately, it is moving away from land areas for the next couple of days.

Yap and Guam are both experiencing the tail end of gusty winds and rains as Tropical Depression 11W moves between the two islands in the western North Pacific today.


The Tropical Rainfall Measuring Mission (TRMM) satellite data was used to create a 3-D image of Tropical Depression 11W's rainfall and cloud heights as it passed overhead on July 26. TD11W had towering convective storms near their centers of circulation that extended to heights above 15km (~9.3 miles) with heavy rainfall, falling at 2 inches (50 mm) per hour.

At 0900 UTC (5 a.m. EDT) on July 27, Tropical Depression 11W's (TD11W) maximum sustained winds were still near 30 knots (34 mph). It was located about 290 nautical miles southwest of Andersen Air Force Base, Guam near 10.7 North and 140.5 East. It was moving to the northwest near 12 knots (14 mph).

When NASA's Aqua satellite passed over TD11W on July 26 at 16:05 UTC (12:05 p.m. EDT) the center of circulation appeared much more rounded than it had in the previous days, indicating that the storm was getting better organized. The Atmospheric Infrared Sounder (AIRS) instrument captured the infrared image that showed powerful, high thunderstorms with cold cloud tops surrounded the center of TD11W's circulation, although the center is partially exposed to outside winds. There were also a number of bands of thunderstorms around the center. TD11W is kicking up waves of 12 feet high, and generating rough surf at Yap and Guam.

TD11W is moving around the western edge of a low to mid-level ridge of high pressure, and will continue in a northwestward direction for the next day or two. After that, the ridge is expected to weaken and the storm track will head in a more northeasterly direction.

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
