Mitchel Volk Posted March 2, 2013 Share Posted March 2, 2013 As per wiki - Highest air pressure ever recorded (above 750 meters): 1084.4 mb (32.03 inHg); Tosontsengel, Khövsgöl Province, Mongolia, 19 December 2001.[131] This is the equivalent sea-level pressure; Tosontsengel is located at 1,300 metres (4,300 ft) above sea level. The highest adjusted-to-sea-level barometeric pressure ever recorded (below 750 meters) was at Agata, Evenhiyskiy, Russia (66°53’N, 93°28’E, elevation: 261 m (856.3 ft)) on 31 December 1968 of 1,083.3 hectopascals (31.99 inHg).[132] The discrimination is due to the problematic assumptions (assuming a standard lapse rate) associated with reduction of sea level from high elevations.[131][132]I know that ii is forecast over the ice field so it the real sea level pressure would be different, but it is still impressive.
