On March 14, Tropical Low 17U slowly began to weaken as the storm made landfall on the northeastern border of Western Australia. Several hours later, 17U made a second landfall over the northwestern border of the Northern Territory. Afterwards, TCWC Darwin issued their last bulletin on the storm as it ...

On March 9, an area of low pressure developed to the north of Kimberley. Over the next 3 days, the low moved into the Timor Sea, as the storm slowly intensified. On March 12, TCWC Darwin reported that the storm had intensified into a tropical low, and gave it the ...

Visible by the left edge of this image is Mount Etna, in Sicily, Italy. A white cloud of ash and steam can be seen spewing forth from the volcano, which is already erupting for the third time in 2012. Mount Etna is one of the most active volcanoes in the ...

Tropical Cyclone Irina (14S), located approximately 90 nm east-southeast of Maputo, Mozambique, has tracked southwestward at 06 knots over the past six hours. Maximum significant wave height is 18 feet. Animated infrared satellite imagery shows that TC 14S is regenerating deep convection and turning back into the Mozambique Channel. Despite ...

A thick cloud of dust blows over Ethiopia, Kenya, Uganda and South Sudan, obscuring much of the land below. Some dust reaches the green Lake Tana, in Ethiopia, in the upper right quadrant. Parts of South Sudan, near the green Jur River near the image center, are dust free. A dust storm ...

At 592,800 square kilometres (228,900 sq mi), Madagascar is the world’s 47th largest country and the fourth largest island. Along the length of the eastern coast runs a narrow and steep escarpment containing much of the island’s remaining tropical rain forest. To the west of this ridge lies a plateau ...

Track of TC 10P Tropical Cyclone Jasmine (10P), located approximately 635 nm west-southwest of Tonga, has tracked east-southeastward at 07 knots over the past six hours. animated infrared satellite imagery shows the system has maintained its overall convective structure and consolidation. The cyclone remains compact and symmetric around a well-defined ...

Glacial lakes appearing bright blue in color can be observed in Patagonia by the Andes Mountains and the border between Chile (west) and Argentina (east). The lakes are, from top to bottom, Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino ...

Dust from the Sahara Desert blows off the west coast of Africa and over the Cape Verde Islands. The dust is so thick that it obscures several of the islands, although some interesting cloud patterns are visible through the veil of dust as it thins out. These patterns are cloud ...

The island of Sicily (left) and southern Italy (right) are separated by the Strait of Messina, which connects the Tyrrhenian Sea with the Ionian Sea, within the central Mediterranean.Visible near the eastern coast of Sicily is Mount Etna, and visible off the northern coast are the Aeolian Islands. Mount Etna ...

Visible at the center of this orthorectified image is Maipo, a stratovolcano in the Andes, lying on the border between Argentina and Chile. It is located 90 km south of Tupungato and about 100 km southeast of Santiago. Maipo retains a symmetrical, conical volcanic shape, unlike many of the other ...

The roughly symmetrical patterns of swirls and curves in the clouds in this image are cloud vortex streets, also known as von Karman vortices. They were created by low-level winds rushing over the Cape Verde Islands off the coast of northwestern Africa. Von Karman vortices form nearly everywhere that fluid ...

Dust from the Sahara Desert blows off the coast of Western Sahara and Mauritania and over the Atlantic Ocean. This giant crescent-shaped dust plume spans several hundred kilometers. Here, the dust appears to be blowing southwestward off the coast of Mauritania, but northwestward off the coast of Western Sahara. Visible ...

Tropical Cyclone Funso (08S), located approximately 420 nm east of Maputo, Mozambique, had tracked southeastward at 06 knots over the past six hours. Animated infrared satellite imagery depicts an eye that is beginning to become more ragged with warming cloud tops near the eyewall. Satellite imagery is also showing the ...

This wide-swath ASAR image shows bays along the Texas Coastal Bend, the flat area of land along the Texas coast.  The Coastal Bend includes the barrier islands of Texas and the Laguna Madre (visible in the lower part of the full image). The bays visible here (from northeast to southwest) ...

“Popcorn” clouds hang in a relatively uniform layer over the land by Brazil’s northeastern coast. These clouds form when water vapour is released into the atmosphere by photosynthesizing plants. Water vapour is more buoyant than dry air, so it rises and eventually condenses into clouds like the popcorn clouds shown ...

The three bright blue, roughly parallel lakes in this image of New Zealand’s South Island are (from left to right): Lake Oahu, Lake Pukaki and Lake Tekapo. They are all alpine glacial lakes in the Mackenzie Basin, near the Southern Alps. The bright blue color comes from “glacial flour”, the ...

Sediments line the southern shores of Lake Michigan, one of the North American Great Lakes. In the full image, the entire lake is visible, and the northern shores are sediment free. Lake Michigan is the only one of the Great Lakes that is located entirely within the United States. The city ...

On the right side of this APM image is a system of lagoons (dark green) near the coast of Mexico. Visible on the left side of the image are various rivers, flowing towards the Gulf of Mexico. The lagoons are part of the deltaic plain of the Usumacinta River, in ...
