It is a non-monsoonal precipitation pattern driven by the westerlies. The moisture in these storms usually originates over theMediterranean Sea and the Atlantic Ocean Extratropical storms are a global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterpartswhere the moisture is carried in the lower atmosphere.
