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 in Storms
Cyclones, also known as hurricanes or typhoons, are primarily caused by high ocean temperatures, broad-scale wind systems and clustered thunderstorms, which liberate the heat energy from the ocean surface and transfer it to the cyclone. Ocean temperatures must be higher than 80 degrees Fahrenheit to a depth of at least 150 feet.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 >
Satellite imaging is the primary instrument used for tracking and measuring tropical cyclones in the deep ocean, according to the Weather Channel. Tropical storms tend to form far away from land, putting them out of range of radar, airplane and weather buoy measurement.Full Answer >
