A mid-latitude cyclone, also known as an extratropical cyclone, is a huge low-pressure system of synoptic scale that is found in the middle latitudes. It has a cyclonic flow, but it is not a tropical storm or a hurricane. It causes windy and wet weather, and occurs most often in the United States during the winter season.Continue Reading
Mid-latitude cyclones have a definite life cycle. They originate as a frontal wave, grow to an occluded cyclone and finally die over a period of several days as cut-off cyclones. Their formation is associated with fronts, and they form easily in winter because of the large difference in the temperature between the north pole and the equator. A jet stream, which brings cool air from the north to the southern regions of United States, plays an important part in the location of these cyclones.
One system can cause extreme weather across the entire United States. Sometimes winds with strength similar to hurricane-force winds develop during a mid-latitude cyclone, causing severe damage along the coasts. If the cyclone slows down and persists for an extended period of time over an area, the enormous precipitation, mostly snow, damages trees, power lines, buildings and bridges. The "comma" appearance of a mid-latitude cyclone on satellite pictures makes its identification easy.Learn more about Storms
A hurricane is a tropical cyclone with sustained winds reaching speeds of at least 74 miles per hour, according to The Weather Channel. Hurricanes are classified on a scale of 1 to 5 using the scale Saffir-Simpson hurricane wind scale.Full Answer >
The term for a hurricane in Australia is tropical cyclone or just cyclone. Cyclones that form in the southern hemisphere by Australia rotate clockwise, while those that form north of the equator rotate counter-clockwise.Full Answer >
According to Nasa.gov, Hurricane Katrina formed after the warm rising air in the tropics formed into a cyclone. The hurricane began in the central Bahamas and came ashore as a Category 1 storm in southern Florida. After causing 11 deaths in that state, the storm made a southwestern turn and cut through the warm waters of the Gulf of Mexico.Full Answer >
Cyclone Tracy resulted from a tropical low in the Arafura Sea between New Guinea and Australia, growing quickly into a tropical cyclone in less than 48 hours. When the slow-moving storm reached the warm waters of the Timor Sea, it became more intense and made landfall as a Category 4 cyclone on December 24, 1974, with top wind speeds of 135 miles per hour recorded in the Darwin, Australia airport before the winds ripped off the location's anemometer.Full Answer >
