Tropical cyclone Yasi became much more powerful and was upgraded to a dangerous category fpur tropical cyclone on the Saffir Simpson scale on February 1, 2011.
This infrared AIRS image from NASA\'s Aqua satellite was captured on Feb. 1 at 0247 UTC (Jan. 31 at 9:47 p.m. EST/12:47 p.m. Australia/Brisbane local time) and the storm appears to fill up most of the Coral Sea. The western fringes of the storm were over the Solomon Islands and Vanuatu at that time. The strongest thunderstorms and heaviest rainfall appear in areas false-colored in purple. The light blue areas are out of the range of the satellite instrument and show no data. Credit: NASA JPL, Ed Olsen
A Cyclone Warning is now in effect for Queensland, Australia for coastal areas from Cape Melville to Sarina, extending inland to east of Croydon to Hughenden. A Cyclone Watch is in effect for coastal areas from Lockhart River to Cape Melville, and in the tropical interior north of Winton to Sarina.
Yasi was seen by the Tropical Rainfall Measuring Mission (TRMM) satellite when it passed over on Febuary 1, 2011 at 0356 UTC (Jan. 31 at 10:56 p.m. EST/1:56 p.m. Australia/Brisbane local time). TRMM precipitation data collected with that pass revealed that intensifying Yasi had a small eye surrounded by powerful thunderstorms. The heaviest rainfall was falling mostly on the south and eastern sides of the storm at a rate of about 2 inches (50 mm) per hour. Most of the rainfall in the rest of the storm was moderate, falling at a rate between .78 to 1.57 inches (20-40 mm) per hour.
The precipitation analysis used TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data and was overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS).
Less than one hour before, NASA's Aqua satellite passed over Cyclone Yasi and captured an infrared image of its cold clouds on Feb. 1 at 0247 UTC (Jan. 31 at 9:47 p.m. EST/12:47 p.m. local time). Infrared imagery suggests that the storm appears to fill up most of the Coral Sea, and provided scientists with a 10 nautical mile-wide eye measurement of the storm.
At the time of the AIRS image, the western fringes of the storm were exiting the Solomon Islands and Vanuatu. The strongest thunderstorms and heaviest rainfall were around the center of the storm, and cloud top temperatures in those areas were as cold as or colder than -63 degrees Fahrenheit (-52 Celsius)!
Another satellite passed over Cyclone Yasi earlier. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard NASA's Terra satellite captured a visible image of Cyclone Yasi approaching Australia at 00:00 UTC (7 p.m. EST Jan. 31/10 a.m. local time) on February 1, 2011. Yasi's eye was visible in the image, despite some clouds wrapping into its center.At 1500 UTC (10 a.m. EST, Feb. 1 / 1 a.m. Feb. 2, Australia/Brisbane local time) on February 1, 2011, Cyclone Yasi was packing maximum sustained winds near 120 knots ( 138 mph/ 222 kmh) with higher gusts. That makes Yasi a Category four (out of five) hurricane on the Saffir-Simpson scale. Cyclone-force winds were occurring as far as 50 nm from the center. It was located about 450 miles (724 km) east-northeast of Cairns, Australia near 14.9 South and 153.2 East. It was moving west-southwest near 17 knots (~20 mph/ ~32 kmh).
Unfortunately, the system is expected to continue to intensify due to good outflow, low vertical wind shear (winds that if strong enough can weaken a tropical cyclone) and warm sea surface temperatures.
The Joint Typhoon Warning Center forecasts that the storm will make landfall near Cairns in Queensland by Wednesday, February 2 near 1200 UTC (7 a.m. EST/10 a.m. local time ) at a provisionally forecast strength of 130 knots (149 mph/240 kmh), which is just under being classified as a Category 5 cyclone.
Residents of Queensland should check the Australian Bureau of Meteorology's website for storm updates at: http://www.bom.gov.au/cyclone/ and should heed evacuations and emergency preparedness immediately.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
