A similar coordinated program operates within the State of México , which surrounds Mexico City on three sides.
The systems usually have a horizontal length scale of less than 1,000 kilometres (620 mi) and exist for no more than a couple of days. They are part of the larger class of mesoscale weather systems. Polar lows can be difficult to detect using conventional weather reports and are a hazard to high-latitude operations, such as shipping and gas and ...
Much of the US plunged into cold air. A brutally cold blast of Siberian air has caused temperatures to plummet 20 to 30 degrees below normal from the Canadian border to the Mexican border and ...
The thicker the cold air mass is, the more effectively it can block an invading milder air mass. The depth of the cold air mass is normally shallower than the mountain barrier which created the cold air damming, or CAD. Some events across the Intermountain West can last for ten days. Pollutants and smoke can remain suspended within the stable ...

This TRMM weather satellite shows the wind impact of a Tehuantepecer from December 16, 2000, at 13:15 UTC.. Its leading edge shows up as a rope cloud within the visible and infrared channels of weather satellite images, and since it lies at the leading edge of a density (temperature and dew point) discontinuity, its leading edge by definition it is a cold front, though it has also been ...
