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: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
