A Jet Stream Runs Through It
High above the Earth's surface, rivers of air rush their way around the globe in a high speed current that often spawns side eddies that we on the ground call cyclones. Knowledge of the position of these streams, known as the <i>jet stream</i> because of their speed, is vital to accurate general weather forecasts and severe storm predictions. Knowledge of the location of the jet stream is also important to airlines and other long-distant air transportation.

Jet Streaming Along the Polar Front
The polar front and its associated jet stream have a major influence on the weather conditions surrounding it. Many storms form along the polar front in the vicinity of the jet stream's maximum winds. Because the jet stream is associated with the polar front, media weather maps often include the jet stream's position as a rough indicator of warm and cold air masses.

Weather Bombs: Rapid Storm Development
Weather bombs or bomb cyclones undergo explosive changes in intensity,forming an intense winter storm over a short period when they moved off the land and into the warm Gulf Stream waters off Cape Hatteras. These storms may move up the East Coast to form major snowstorms along their path.

The Great Lakes: Storm Breeding Ground
Our Weather Eye this month focuses on the Great Lakes region. Over the world's largest fresh water bodies, two storm tracks converge in November. When cyclonic systems reach the region, the jet stream above and the warm Great Lakes waters below often induce an even more deadly spin in these storms.

Twinkle, Twinkle: September Skies and Starlight
The lower atmosphere, where we stand to view the stars, is mottled with pockets of varying density. When the local air density changes rapidly with time, the light ray's path also alters rapidly. This slight but perceptible refraction bends the path one way, one moment, slightly different the next. This constant, but random shifting results in the star's image jiving and jiggling, fading in and out, and even changing colours before our eyes. This stellar dancing is what we call "twinkling."

Nor'easters and Alberta Clippers
The great tropical storms roaming the world's oceans and seas have earned the right for individual names. Extratropical cyclonic storms, those forming from the clash of polar and tropical air masses, have not yet been honoured with individual names. However, some extratropical storms take on such unique characteristics that they are often recognized with a unique name for the genre: the Nor'easter along the Atlantic coast, the Alberta Clipper that races across the continent our of the Alberta plains.
