Satellite spots Tropical Storm Nadine and 2 developing lows

24.09.2012
NOAA's GOES satellite captured Tropical Storm Nadine in the eastern Atlantic, another low pressure area forming in the central Atlantic, and a developing low in the eastern Pacific. NASA's TRMM satellite noticed that the storms around Nadine's center were waning.

On Sept. 21 at 7:45 a.m. EDT, NOAA's GOES-13 satellite captured an image of Tropical Storm Nadine in the eastern Atlantic, and a developing low in the central Atlantic. Nadine is south of the frontal boundary draped across the Azores islands. NOAA's GOES-13 satellite sits in a fixed orbit over the eastern U.S. and captures continuous visible and infrared imagery of the eastern U.S. and the Atlantic Ocean. The image was created by NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite flew over Tropical Storm Nadine twice on Sept. 21. The first TRMM overpass happened at 0822 UTC (4:22 a.m. EDT) and the second at 1001 UTC (6:01 a.m. EDT). TRMM can see rainfall occurring within a tropical cyclone and noticed that Tropical Storm Nadine's center of circulation has cleared of convection (rising air that forms thunderstorms) and thunderstorms since TRMM passed overhead on Sept. 20. TRMM data on Sept. 21 showed convective rainfall near Nadine's center of circulation had ended and bands of light to moderate rainfall were wrapping around Nadine's southern side. TRMM is a joint mission between NASA and the Japanese Space Agency, and imagery is created at NASA's Goddard Space Flight Center in Greenbelt, Md.

At 1500 UTC (11 a.m. EDT) on Friday, Sept. 21, 2012 Tropical Storm Nadine had maximum sustained winds were near 60 mph (95 kph). The center of Tropical Storm Nadine was located near latitude 34.1 north and longitude 27.5 west, about 270 miles (435 km) south of the Azores islands. Nadine is moving toward the south near 10 mph (17 kmh) and is expected to turn toward the southeast followed by a turn east over the weekend of Sept. 22 and 23. Although there is little change expected in Nadine's intensity over the next day or two, the storm could become post-tropical. Forecasters noted that dry air has moved into the center of Nadine's circulation, sapping the energy in the thunderstorms. In addition, sea surface temperatures are hovering near the 26.6 Celsius (80 degree Fahrenheit) threshold needed to keep a tropical cyclone alive.

The Developing Atlantic Low Pressure Area

There's a non-tropical low pressure area in the central Atlantic Ocean that was also picked up on the GOES-13 satellite image from today, Sept. 21. The low is located about 450 miles east of Bermuda and the shower and thunderstorm activity didn't change much from the previous day. This low is tracking to the north-northwest into cooler waters, which will drop its chances for developing into a sub-tropical depression. In the meantime, it has a 50 percent chance of making it to sub-tropical depression status before hitting the cooler waters.

The Developing Eastern Pacific Low Pressure Area

The low pressure area off the western coast of Mexico has a better chance of development than its Atlantic counterpart, and as a tropical depression, not a sub-tropical one. Satellite data show that the low appears to be getting organized and has a visible appearance of circulation. The low is located about 400 miles south of the southern tip of Manzanillo, Mexico and is moving to the west-northwest. The National Hurricane Center noted that conditions are ripe for development with low wind shear and warm sea surface temperatures. There's a 70 percent chance that this low could become the thirteenth tropical depression of the Eastern Pacific hurricane season. If it develops into a tropical storm over the weekend of Sept. 22 and 23, it would be named Miriam.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

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...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
