Explanation / Answer

We know that the barometers are placed at certain altitude while taking the readings and due to placing it at certain altitude it gives the less reading than on the sea level because with rising height the pressure goes down and also due to gravitation effect mercury climbs less thats why it gives us the less reading as we go up

1).

at some altitude

mean pressure =999 mb

barometric pressure raw = 997mb

pressure difference= 997- 999 = -2 mb

here the pressure is less by 2 mb

at sea level just on the surface of sea

mean sea level pressure for Ashville Carolina = 1013mb

corrected pressure would be = 1013mb + (-2mb) = 1011 mb

2).

at some altitude

mean pressure =999 mb

barometric pressure raw = 1003mb

pressure difference= 1003- 999 = 4 mb

here the pressure is increases by 4 mb

at sea level just on the surface of sea

mean sea level pressure for Ashville Carolina = 1013mb

corrected pressure would be = 1013mb + (4mb) = 1017 mb
