Winter is one of the four seasons of temperate zones. Meteorological winter is the season having the shortest days (which vary greatly according to latitude) and the lowest temperatures. During winter, there is much snow and cold, especially in areas that are farther away from the Equator. Blizzards often develop and cause many delays. A rare meteorological phenomenon encountered during winter is ice fog, which is composed of ice crystals suspended in the air and occurs only at very low temperatures (at least 10 degrees below zero).
