Amritsar (31º29'–32º03’N) and Shimla (30º45'–31º44' N) lie almost on the same latitude, but the difference in their climate is due to the difference in their altitude. Amritsar’s height above sea level is about 230 metres, whereas Shimla’s height above sea level is about 2,200 metres. In the troposphere, as altitude increases, temperature keeps decreasing.
