Why are measured values of air pressure changed when placed on a weather map?
What will be an ideal response?
Answer: Elevation affects air pressure greatly so readings are "corrected" to sea level values. If not corrected, important meteorological variations would be masked. In short, it's a way to get every reading on the "same page."
