The Talesh Mountains are stretched in a north to south direction, and the Alborz Mountains in an east to west direction. These serve as a barrier against the humid north-west Caspian winds and withhold the penetration of wind bearing vapors towards Iran's mainland, causing heavy rainfall in Gilan during the Spring and Fall seasons.
