The spelling of Teheran is going more and more in direction of "Tehran". The name comes from Old Persian "teh ran", meaning “warm place.” Teheran has warm summers and cold winters, often with snow. Rainfall is only 200 mm annually.
In modern times, Teheran suffers from extreme air pollution, most of it originating from the heavy traffic and the use of oil by the industry. Some measures have been taken to help this problem, like encouraging buses and taxis to use compressed natural gas instead of petroleum. A 3 line underground rail system also helps reduce the heavy traffic.
