Below is information relating atmospheric pressure to altitude relative to sea level: The atmospheric pressure at sea level is 7
60 mmHg. The atmospheric pressure of the Dead Sea (0.40 km below sea level) is 800 mmHg. The atmospheric pressure of Los Angeles (0.09 km above sea level) is 752 mmHg. The atmospheric pressure of Mount Whitney (4.50 km above sea level) is 440 mmHg Based on the information above, which location would have the highest atmospheric pressure? San Diego, CA (at sea level) Mauna Kea, HI (4205 m above sea level) New Orleans, LA (2 m below sea level) Memphis, TN (59 m above sea level)
In this examples, we can see that the places with the highest altitude (meters above sea level) are also the places with the lowest atmospheric pressure. Therefore, we can conclude that the opposite is true too. The places with the lowest altitude are the ones with the highest atmospheric pressure. The place with the lowest altitude is New Orleans, as it is located 2 m below sea level.
