A mid-latitude cyclone is a large scale area low pressure and cyclonically rotating air that occurs in the middle latitudes (i.e. neither tropical nor polar). Cyclonic rotation is defined as counterclockwise in the northern hemisphere and clockwise in the southern.Unlike tropical cyclones, such as hurricanes, mid-latitude cyclones are powered by temperature contrasts, usually along boundaries between large-scale air masses.These systems develop a system of fronts, usually with a warm front on the eastward side and a cold front on the equatorward side.yclonic rotation is defined as counterclockwise in the northern hemisphere and clockwise in the southern. Unlike tropical cyclones, such as hurricanes, mid-latitude cyclones are powered by temperature contrasts, usually along boundaries between large-scale air masses.
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are an everyday phenomenon which, along with anticyclones, drive the weather over much of the Earth. They are capable of producing anything from cloudiness and mild showers to heavy gales and thunderstorms.xtratropical cyclones encompass a class of storms with many names. The term  cyclone  applies to numerous types of low pressure areas. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics in the middle latitudes of Earth.
