NASA sees Chris become first hurricane of Atlantic season

22.06.2012
NASA satellites monitoring the life of Chris in the Atlantic saw the tropical storm become the first hurricane of the Atlantic Ocean season on June 21, 2012.

Infrared satellite imagery from NASA's Aqua satellite have revealed that the clouds around Hurricane Chris' eye have reached a cold peak early on June 21 when it was first designated a hurricane, and have since warmed.

The thunderstorms that surround Chris' eye are now between -60 and -70 Celsius. Cloud top temperatures that cold indicate strong, high, thunderstorms with the potential for heavy rainfall.

When thunderstorm cloud tops cool, it means there's more uplight in the atmosphere, which can push cloud tops higher and build stronger thunderstorms. When cloud top temperatures warm, it means the cloud tops are falling, and the push of the air upward is lesser than it was before, and the storm is weakening. As a result, forecasters at the National Hurricane Center expect Chris to become a post-tropical cyclone on Friday, June 22. That weakening is expected because Chris is moving into stable air and cooler waters.

NOAA's GOES-13 satellite captured a visible image of Chris on June 21 at 1445 UTC (10:45 a.m. EDT). The image was created by NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. and it showed Hurricane Chris with a tight circulation center.

At 11 a.m. EDT, Chris had 75 mph (120 kph) winds. It was located about 625 miles (1005 km) southeast of Cape Race, Newfoundland, Canada, near 41.1 North and 43.2 West. It was moving to the northeast at 20 mph (32 kph) and had a minimum central pressure of 987 millibars.

Chris is expected to turn in the Altantic over the next couple of days. First a turn to the north and then northwest and finally south. Chris is moving around a large mid-to-upper level low pressure area and will eventually become absorbed within the upper level low in the next couple of days.

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
