Volcanic eruption in Chile

Puyehue-Cordón Caulle eruption
+ Full-Sized Image

This natural-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite shows the thick, brown ash plume from the June 4, 2011 eruption of the Puyehue-Cordón Caulle Volcano Complex in Chile. The plume is easily identified as it towers over the bright white clouds in this scene.

Waterspout in Australia

Dramatic footage filmed from a helicopter by Australia’s Channel 7 shows a series of powerful waterspouts near the coastal suburb of Terrigal, on Australia’s New South Wales coast. Several powerful columns of swirling air could be seen blasting along the water’s surface near the coastline. Channel 7 claimed the spouts reached heights of up to 600 metres (nearly two thousand feet), but dissipated as they neared land. The natural wonders came as strong winds and heavy rain also lashed other parts of the state, causing flash flooding and traffic chaos in Sydney. Watch video:

La Niña imaged from sea temperature data

Weakening of La Niña but Above Normal Hurricane Season is Predicted

Last week, NOAA issued the 2011 Atlantic Hurricane Season Outlook, which predicts an above-normal year for activity. Though the La Niña continues to weaken in the Pacific, it will continue to effect weather patterns and influence the number of storms that are predicted. During La Niña years, wind shear is reduced in the Tropical Atlantic, creating conditions that are ideal for tropical cyclone formation. This image shows how the sea surface temperatures have changed, on average, from mid-April to mid-May. A warming signature is clearly visible as indicated by the red areas in the Eastern Equatorial Pacific region, an indication of La Niña’s waning strength. Also related to the Atlantic Hurricane Season, warming trends are visible in the Caribbean and Eastern Gulf of Mexico.

Black Forest storms

When the weather conditions are right the Black Forest in southern Germany can turn into a thunderstorm factory. This picture shows three cells in various stages of development, all matured into thunderstorms over the rest of the day. The view is taken from just across the border in northern Switzerland.  Image by Neil Jones.
