NASA Satellite Imagery Shows Some Punch Left in System 94S

17.01.2014
The tropical low pressure area known as System 94S still has some punch in it as the low-level center of circulation continues to track over Western Australia and the Northern Territory.

NASA's Aqua satellite showed that thunderstorms in the low had the potential for heavy rain as it continues to track over land, and heavy rainfall warnings are in effect in the Northern Territory.

NASA's Aqua satellite passed over System 94S on January 15 at 11:59 a.m. EST and the Atmospheric Infrared Sounder instrument saw a band of powerful thunderstorms northwest of the center of the broad circulation center entering the Timor Sea from Northern Territory, Australia. Some of the thunderstorms were very high, and cloud top temperatures colder than -63F/-52C. Those temperatures are conducive to a NASA study that indicates the potential for those storms to have heavy rainfall rates.

On January 16 at 08:30 UTC/3:30 a.m. EST/6 p.m. Darwin local time, System 94S was centered about 370 nautical miles east of Broome, Australia near 18.6 south and 128.6 east. System 94S continues to track to the west and computer models indicate that it may re-emerge in the waters of the Southern Indian Ocean in the next 4 to 5 days.

The Australian Government Bureau of Meteorology or ABM for the Northern Territory issued a Severe Weather Warning for heavy rainfall and flash flooding on January 16 as the low continued to move slowly west. The warning was for residents in the Victoria River and northwest Alice Springs Districts and it was issued at 10:29 p.m. CST/local time.

At 1200 UTC/7 a.m. EST/9:30 p.m. CST/Darwin local time, System 94S was centered near latitude 19.5 south and longitude 128.7 east about 99.4 miles/160 kilometers west northwest of Rabbit Flat. The ABM forecasts the low to move south along the western border of the Northern Territory.

The Joint Typhoon Warning Center or JTWC reported that animated multispectral satellite imagery and the radar loop from Halls Creek, Australia, showed a defined circulation center with several bands of convection wrapping around the center (which is still over land). Maximum sustained surface winds were estimated as high as 20 knots.

Currently, the JTWC gives this system a low chance for development into a tropical cyclone over the next day or two.

Im Focus: Production of an AIDS vaccine in algae

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.

The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...

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).
