Cyclone Oli reaches category 4 strength on its way to open waters

05.02.2010
Oli has exploded in strength and as of February 4 it was a Category 4 cyclone with peak sustained winds of 132 mph (115 knots/213 km/hr). NASA's Aqua and TRMM satellites observed Oli's clouds grow colder and rainfall become heavier over the last day. Residents of French Polynesia should watch for local weather advisories.

The Tropical Rainfall Measuring Mission or TRMM satellite is like a rain gauge in space. It's managed by NASA and the Japanese Space Agency, and can measure rainfall in a cyclone from its orbit above the Earth. Yesterday, the TRMM satellite flew almost directly over Tropical Cyclone Oli and revealed that Oli had a large circulation and that its converging rain bands were causing additional rainfall in distant Bora Bora and Tahiti. In some areas of the storm, rain was falling at more than 2 inches (50 millimeters) per hour.

Earlier today, February 4, NASA's Aqua satellite flew over Oli and showed very high thunderstorm cloud tops, so high they were colder than -63F (-52C), and dropping heavy rainfall.

At 10 a.m. ET (1500 UTC) February 4, Tropical Cyclone Oli was located about 250 miles west-southwest of Bora Bora, ear 18.6 South and 152.4 West. Cyclone (hurricane) force winds extend only to about 35 miles (56 kilometers) from the center. From there, tropical storm-force winds extent out as far as 145 miles, so Bora Bora and Tahiti will likely experience breezy conditions and winds likely below tropical storm force (because they are farther out). Oli keeps moving south-southeast near 10 mph (9 knots/16 km/hr). Oli continues to cause very high seas, up to 23 feet (7 meters).

French Polynesia had not posted any warnings as of 12 p.m. ET on February 4 (17:00 UTC), but residents can expect dangerous surf and on-and-off showers and thunderstorms, some with heavy rainfall and gusty winds.

On February 4 during the morning hours (Eastern Time) sustained winds have been averaging about 30 mph (48 km/hr), and temperatures are hovering around 80F (29C). Earlier, some heavy rain was reported. For updated weather observations in Tahiti, go to: http://weather.noaa.gov/weather/current/NTAA.html.

Oli is expected to strengthen more until late in the day on February 5, then will start weakening. Oli is expected to transition into an extra-tropical system over the weekend.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
