Weather prediction: Expect more wet and unsettled conditions

The barometric pressure in Tehran varies throughout the year. It is affected by the city's location in a valley. This unique geography influences the pressure.
Tehran is surrounded by mountains to the north and east. The Alborz Mountains to the north block airflow from the Caspian Sea. This leads to a rain shadow effect. The Zagros Mountains to the east also impact airflow.
The city's valley location traps warm air. This makes the pressure lower than in surrounding areas. The mountains also force air to rise, cool, and condense, resulting in precipitation.
