2 NASA satellites spy Alberto, the Atlantic Ocean season's first tropical storm

22.05.2012
The first tropical storm of the Atlantic Ocean hurricane season formed off the coast of South Carolina on Saturday, May 19, 2012 at 5 p.m. EDT, and NASA satellites were immediately keeping track of it. NASA's TRMM and Aqua satellites have provided a visible look at the compact storm and its rainfall rates.
Tropical Storm Alberto formed 13 days before the official start of hurricane season (June 1) and ramped up quickly. Alberto's maximum sustained winds jumped to 45 mph after it developed. It was located about 140 miles east-southeast of Charleston, South Carolina, and would then take a southerly track.

On that same day, NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Alberto. TRMM data showed a large area of moderate to heavy rainfall with a small area of heavy rainfall located near the center of the forming tropical cyclone. Data from two instruments aboard TRMM provided the rainfall data: the Microwave Imager (TMI) and Precipitation Radar (PR) data captured at 12 minutes after midnight EDT.

On Sunday, May 20, Tropical Storm Alberto had strengthened. A Tropical Storm Watch was posted and later dropped for Savannah River to South Santee River, South Carolina. At that time, Alberto's maximum winds were near 50 mph. By mid-day, Alberto's center was located near 31.7 North and 79.3 West, about 95 miles south-southeast of Charleston, S.C. Alberto was moving west-southwest at 6 mph. Pressure 998 millibars. By 11 p.m. EDT on Sunday, May 20, Alberto appeared to become less organized and weakened. Alberto's maximum sustained winds dropped to 40 mph (65 kph) and it was centered about 85 miles (135 km) east-northeast of St. Augustine, Florida.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard NASA's Aqua satellite captured a stunning visible image of Tropical Storm Alberto off the Georgia coast on May 20 at 18:30 UTC (3:30 p.m. EDT) that showed it is a compact storm with a tight center of circulation.

On Monday, May 21, Tropical Storm Alberto was still moving southeast and is about 100 miles east-southeast of St. Augustine Florida. Alberto is causing dangerous surf conditions, including rip currents along the Georgia, South Carolina and northeast Florida coastlines.

The National Hurricane Center forecast calls for Alberto to remain off-shore from Georgia and South Carolina, and then turn to the east and then to the northeast. Although there is no expected change in the strength of Alberto as it turns, the tropical storm is churning up the waters along the coasts of South Carolina, Georgia and northern Florida, causing rough seas and rip tides.

On the day Alberto formed, May 19, NASA's TRMM satellite captured a look at the rainfall rates within the first tropical storm of the Atlantic season. TRMM data showed a large area of moderate to heavy rainfall (falling at a rate of 2 inches/50 mm per hour seen in red) with a small area of heavy rainfall located near the center of the forming tropical cyclone. Light to moderate rainfall was falling at a rate between .78 inches and 1.57 inches per hour (20 to 40 mm). Credit: NASA/TRMM, Hal Pierce

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

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.
