NASA Sees Large Tropical Cyclone Yasi Headed Toward Queensland, Australia

NASA image acquired January 30, 2011 at 23:20 UTC. Satellite: Terra Click here to see the most recent image captured Feb. 1: <a href="http://www.flickr.com/photos/gsfc/5407540724/">www.flickr.com/photos/gsfc/5407540724/</a> Tropical Storm Anthony made landfall in Queensland, Australia this past weekend, and now the residents are watching a larger, more powerful cyclone headed their way. NASA's Terra satellite captured a visible image of the large Tropical Cyclone Yasi late yesterday as it makes its way west through the Coral Sea toward Queensland. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA's Terra satellite captured an image of Cyclone Yasi on Jan. 30 at 23:20 UTC (6:20 p.m. EST/09:20 a.m., Monday, January 31 in Australia/Brisbane local time). Although the image did not reveal a visible eye, the storm appears to be well-formed and also appears to be strengthening. Warnings and watches are already in effect throughout the Coral Sea. The Solomon Islands currently have a Tropical Cyclone warning for the provinces of Temotu, Rennell & Bellona, Makira and Guadalcanal. The Australian Bureau of Meteorology has already posted a Tropical Cyclone Watch from Cooktown to Yeppoon and inland to between Georgetown and Moranbah in Queensland, Australia. The Australian Bureau of Meteorology expects damaging winds to develop in coastal and island communities between Cooktown and Yeppoon Wednesday morning, and inland areas on Wednesday afternoon. Updates from the Australian Bureau of Meteorology can be monitored at the Bureau's website at <a href="http://www.bom.gov.au" rel="nofollow">www.bom.gov.au</a>. On January 31 at 1500 UTC (10 a.m. EST/ 1:00 a.m. Tuesday February 1, 2011 in Australia/Brisbane local time), Tropical Cyclone Yasi had maximum sustained winds near 90 knots (103 mph/166 kmh). Yasi is a Category Two Cyclone on the Saffir-Simpson Scale. It was centered about 875 miles E of Cairns, Australia, near 13.4 South latitude and 160.4 East longitude. It was moving west near 19 knots (22 mph/35 kmh). Cyclone-force winds extend out to 30 miles (48 km) from the center. Animated infrared satellite imagery, such as that from the Atmospheric Infrared Sounder (AIRS) that flies on NASA's Aqua satellite, showed deep convective (thunderstorm) bands wrapping tighter into the low level circulation center. Wrapping bands of thunderstorms indicate strengthening. Yasi is forecast to move west then southwestward into an area of low vertical wind shear (strong wind shear can weaken a storm). Forecasters at the Joint Typhoon Warning Center (JTWC) expect Yasi to continue strengthening over the next 36 hours. JTWC forecasts a landfall just south of Cairns as a large 100-plus knot (115 mph/185 kmh)n system by Wednesday. Residents along the Queensland coast should now be making preparations now for the storm's arrival.

Unsettled weather across central Australia

In late July 2013, a low pressure system off Australia’s southeast coast and moist onshore winds combined to create unsettled weather across central Australia – and a striking image of a broad cloud band across the stark winter landscape. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on July 22 at 01:05 UTC (10:35 a.m. Australian Central Standard Time). To the west of the low pressure trough the skies are clear and dry. To the east, the broad band of bright white clouds obscures the landscape. The system brought wind, precipitation and cooler temperatures to the region. The same day as MODIS captured this image, the Naval Research Lab (NRL) published an edition of the Global Storm Tracker (GST), which gave a world-wide view of the low-pressure systems across the world. This tracker shows the entire cloud band across Australia, as well as the location of the low pressure system. A good view of the Storm Tracker is provided by Red Orbit at: <a href="http://www.redorbit.com/media/uploads/2013/07/072213-weather-003-storm-tracker.jpg" rel="nofollow">www.redorbit.com/media/uploads/2013/07/072213-weather-003...</a> Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team <a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a> <a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

Powerful Tropical Cyclone Ita Making Landfall in Queensland, Australia

NASA's Aqua satellite passed over Tropical Cyclone Ita as it began making landfall on the Eastern Cape York Peninsula of Queensland, Australia, today, April 11, 2014. Ita officially made landfall at Cape Flattery about 9:00 p.m. local AEST time as a Category 4 storm according to reports from the Australian Broadcasting Corporation (ABC). The Moderate Resolution Imaging Spectroradiometer that flies aboard Aqua captured an image of the Category 4 storm on April 11 at 12:00 a.m. EDT (4 a.m. UTC). Satellite imagery indicates the eye is 9.2 miles wide (8 nautical miles, or 14.8 km). Warnings and watches remain in effect as the center of Ita is expected to remain at hurricane strength as it moves in a southerly direction, staying just west of Cairns over the next day. A tropical cyclone warning is in effect between Coen and Innisfail, including Cooktown, Port Douglas, Cairns, extending inland to Kalinga, Palmerville, Mareeba and Chillagoe. A tropical cyclone watch is in effect between Innisfail to Cardwell, extending inland. ABC reported that the strongest maximum sustained winds around the center of circulation were near 142.9 mph (124.2 knots, or 230 kph) and many trees have been downed and homes damaged. According to ABC, preliminary reports suggest that power may be out for a month in some areas. On April 11 at 5 a.m. EDT (9 a.m. UTC), Tropical Cyclone Ita had maximum sustained winds near 143.8 mph (125 knots, or 231.5 kph). It was centered near 14.8 degrees south latitude and 145.3 degrees east longitude, about 168 miles (146 nautical miles, or 288 km) north of Cairns, Australia, and has tracked south-southwestward at 10.3 mph (9 knots, or 16.6 kph). Ita is moving around a subtropical ridge (elongated area) of high pressure and the Joint Typhoon Warning Center expects Ita to start curving to the southeast around that ridge in the next day before heading back out into the Coral Sea.

Mackenzie Bay, Antarctica

Off the northeastern edge of Antarctica’s Amery Ice Shelf lies Mackenzie Bay, which was painted with a ghostly blue-green mass in early February 2012. Similarly colored tendrils also streamed northward across the ocean, their flow sometimes interrupted by icebergs. Multiple factors might account for the ghostly shapes, including low-lying clouds or katabatic winds—downslope winds blowing toward the coast, which can freeze the water at the ocean surface. But an intriguing and perhaps more likely explanation involves processes occurring below the ice shelf. An ice shelf is a thick slab of ice often fed by glaciers attached to the coastline. The shelf floats on the ocean surface, with seawater circulating underneath. Like most ice shelves, the Amery is very thick in the upstream area near the shore. It thins significantly as it stretches northward away from the continent. Water at depth is subject to much greater pressure than water at the surface, and one effect of this intense pressure is that it effectively lowers the freezing point. So water circulating at depth beneath the Amery Ice Shelf may be slightly below the temperature at which it would normally begin to freeze. As some that water wells up along the underbelly of the shelf, the pressure is reduced and the water begins to freeze even though the temperature may not change. As it freezes, this deep-ocean water forms needle-like crystals known as frazil. The crystals are only 3 to 4 millimeters (0.12 to 0.16 inches) wide, but a sufficient concentration of frazil can change the appearance of the water. A frazil-rich plume probably accounts for the blue-green waters off the Amery Ice Shelf in the image above. Modeling of ocean circulation beneath the shelf indicates just such a plume emerging in that location. Frazil-rich water explains the plume, and wind transport of the surface water explains the long streams extending northward. As the sub-iceshelf water mixes with surface water around the Antarctic coastline, the frazil is gradually melted and the streams disappear. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image of Mackenzie Bay and the ice shelf on February 12, 2012.
