>> Practically such a high pressure you will experience thousands of feet below mean sea level.The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968. This pressure corresponds to being at an altitude of nearly 600 m (2,000 ft) below sea level! Made more amazing by the fact that
