NASA Sees a Weaker Tropical Storm Marie

29.08.2014

When NOAA's GOES-West satellite captured an image of what is now Tropical Storm Marie, weakened from hurricane status on August 28, the strongest thunderstorms were located in the southern quadrant of the storm.

NOAA's GOES-West satellite captured an image of Marie on August 28 at 11 a.m. EDT. Bands of thunderstorms circled the storm especially to the north.


This image of Tropical Storm Marie was captured by NOAA's GOES-West satellite on August 28 at 11 a.m. EDT and showed the strongest storms were south of the center.

The National Hurricane Center noted that Marie has continued to produce a small area of convection (rising air that forms the thunderstorms that make up Marie) south and east of the center during some hours on the morning of August 28. The GOES image was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Infrared data, such as that from the Atmospheric Infrared Sounder instrument aboard NASA's Aqua satellite showed that cloud tops had warmed.

Warming cloud tops means that the strength in the uplift of air (that pushes cloud tops higher into the colder levels of the atmosphere) has weakened, and clouds are not getting as high as they did before. The higher the thunderstorms, the stronger they usually are, but Marie's are dropping in height.

Marie is not able to generate strong thunderstorms because it has moved over cooler waters. Sea surface temperatures of at least 80 F (26.6 C) are needed to maintain a hurricane's strength. Marie is in waters as cool as 22C (71.6F).

At 11 a.m. EDT (1500 UTC) Marie's maximum sustained winds were down to 45 mph (75 kph) and weakening. Marie was centered near latitude 25.4 north and longitude 128.9 west, about 865 miles (1,395 km) west of Punta Eugenia, Mexico. Marie is moving northwest at 15 mph (24 kph).

The NHC expects Marie should become post-tropical by tonight, August 28. Meanwhile Marie continues kicking up rough surf.

Large southerly swells affecting much of the west coast of the Baja California peninsula and the coast of southern California will gradually subside through Friday, August 29. These swells could still produce life-threatening surf and rip currents, as well as minor coastal flooding around the time of high tide.

Im Focus: The most accurate optical single-ion clock worldwide

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Im Focus: Flow phenomena on solid surfaces: Physicists highlight key role played by boundary layer velocity

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.

The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
