NASA sees a strengthening Tropical Storm Ernesto

07.08.2012
Tropical Storm Ernesto continues to track through the Caribbean and satellite data and NOAA hurricane hunter aircraft revealed a strengthening storm mid-day on Monday, August 6.

NASA infrared data revealed strong thunderstorms on August 5 that indicated a strengthening storm, and the GOES-13 satellite showed a well-organized tropical storm 24 hours later.


NASA's Aqua satellite passed over Tropical Storm Ernesto on Aug. 5 at 1753 UTC (1:53 p.m. EDT). The AIRS instrument captured an infrared image of the eastern half of the storm where cloud temperatures exceeded -63 Fahrenheit (-52 Celsius) indicating strong thunderstorms with heavy rainfall (purple).

NOAA's Hurricane hunter aircraft investigated Tropical Storm Ernesto on the morning of August 6 and found deep convection (rising air that forms the thunderstorms that make up a tropical cyclone) and that the center was actually located northeast of where previously thought.

NASA's Aqua satellite passed over Tropical Storm Ernesto on August 5 at 1753 UTC (1:53 p.m. EDT) when the storm's maximum sustained winds were near 50 mph (85 kmh). The Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the eastern half of the storm where cloud temperatures exceeded -63 Fahrenheit (-52 Celsius) indicating strong thunderstorms with heavy rainfall. Ernesto continued to strengthen after Aqua passed by.

NOAA's GOES-13 satellite has been continuously providing imagery of Ernesto. A visible image of Tropical Storm Ernesto from GOES-13 on August 6 at 11:45 a.m. EDT showed an organized, rounded storm with strong convection (rising air that forms the thunderstorms that make up a tropical cyclone).

At 11 a.m. EDT (1500 UTC) Tropical Storm Ernesto's maximum sustained winds were near 65 mph (100 kmh). The National Hurricane Center (NHC) expects Ernesto to strengthen into a hurricane later in the day. The center was only 190 miles (205 km) east-northeast of Cabo Gracias A Dios on the Nicaragua/Honduras border, near latitude 15.8 north and longitude 80.5 west. Ernesto is moving toward the west-northwest near 9 mph (15 kmh) and that general motion is expected to continue for the next two days. Because Ernesto has continued moving west, the Cayman Islands discontinued their tropical storm watch for Grand Cayman. The NHC noted that "Ernesto's center will be passing north of the coast of Honduras tonight and Tuesday and approach the east coast of the Yucatan peninsula early Wednesday."

The NHC summarized the watches and warnings in effect today, August 6, 2012: The government of Mexico has issued a hurricane warning for the east coast of the Yucatan peninsula from Chetumal northward to Punta Allen and has issued a tropical storm warning from north of Punta Allen to Tulum. The government of Mexico has also issued a Tropical Storm Watch from north of Tulum to Chetumal. In Belize, there's a hurricane watch for the entire coast.

Ernesto is expected to strengthen to hurricane status by the end of the day on Monday, August 6.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
