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.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
