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.Know More
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
Typhoons, cyclones and hurricanes are all the same type of weather phenomenon; the only difference is the location of the storm, according to the National Ocean Service. In the Atlantic Ocean and northeast Pacific Ocean, the term "hurricane" is used. Cyclones occur in the South Pacific and Indian Oceans, while typhoons are in the northwest Pacific Ocean.Full Answer >
The 1970 Bhola cyclone was the deadliest tropical cyclone of all time, claiming between 300,000 and 500,000 lives in the Ganges River Delta and causing approximately $490 million worth of damage in U.S. dollars. Its strength equaled that of a category 3 hurricane.Full Answer >
There are four stages of tropical cyclones, which are tropical disturbance, tropical depression, tropical storm and hurricane or typhoon. In terms of the life cycle of a tropical cyclone, which on average lasts for nine days, it passes through four phases as well.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 >
