Seasonal Weather

The Aboriginal people of Australia had their own way of defining the seasons, based on local weather patterns. Australia’s Bureau of Meteorology has created a Web site that illustrates several of these seasonal weather calendars, established thousands of years ago. Unlike the European and American spring, summer, autumn, and winter, the indigenous versions often include […]

Ash Clouds: Severe storms can lift smoke into stratosphere

New field observations, satellite images, and computer models suggest that a severe thunderstorm, enhanced by heat from forest fires, can boost soot, smoke, and other particles as far as the lower stratosphere, an unexpected phenomenon.
