NASA Satellite Sees Tropical Storm Cyril a Strong, Compact Storm

08.02.2012
Tropical Storm Cyril was known as "11P" has been strengthening since February 6, and still appears very compact on infrared NASA satellite data.

In the morning hours of February 7 (local time Vanuatu) Cyril was located south of the island of Vavau in the Kingdom of Tonga. All warnings for Niue and Tonga have now been cancelled.

During the morning hours of February 7, Cyril picked up speed and is moving to the southeast at 28 knots (~32 mph/~52 kph). Cyril's maximum sustained winds were near 45 knots (~52 mph/~83 kph). Those tropical-storm-force winds only extended out to 35 miles (~56 km), making the storm over 70 miles (~113 km) in diameter. Satellite imagery from February 6 helped forecasters estimate that the clouds associated with Cyril extended to 120 miles in diameter.

By 1500 UTC on February 7 (10 a.m. EST or 4 a.m. on Feb. 8 Pacific/Tongatapu local time) Cyril was centered about 545 nautical miles (627 miles/1,009 km) south of Pago Pago, American Samoa near 23.8 South and 165.0 West. Cyril covered 175 nautical miles (~196 miles/~315 km) in 12 hours during the morning hours of February 7.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of Cyril's clouds on February 7, 2012 at 12:29 UTC. Cyril still appears as a very compact, rounded storm. The strongest thunderstorms remained close to the center of circulation where cloud top temperatures are below -63 F (-52.7C).

The Australian Broadcasting Corporation noted that the Vavau airport reported sustained winds of 45 knots (~52 mph/~83 kph) on Feb. 8 at 6:30 a.m. local Pacific/Tongatapu time.

As Cyril continues to speed to the southeast, the vertical wind shear is forecast to increase and sea surface temperatures are expected to be much cooler. In fact, water temperatures will decrease to 25 degrees Celsius (77F) and colder. Sea surface temperatures must be at least 26.6C (80F) to support a tropical cyclone, otherwise the system begins to weaken. The Joint Typhoon Warning Center gives Cyril two days before it dissipates.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
