Question

Suppose an air mass forms over Region 1. What characteristics would you expect the air mass to have? Why?

Answer 1

Answer:

When an air mass moves over a new region, it shares its temperature and humidity with that region. So the temperature and humidity of a particular location depends partly on the characteristics of the air mass that sits over it. Storms arise if the air mass and the region it moves over have different characteristics.

Explanation:Air masses are relatively large bodies of air that are fairly horizontally uniform in characteristics. They have relatively uniform temperature and moisture content; the region separating two different air masses is called a front.

This location is the source region. Air masses are NAMED by their temperature and humidity characteristics. The humidity characteristic is derived from the type of surface over which the air mass sits.
