Air Masses Air whose properties of temperature and moisture content (humidity), at any given altitude Classification: polar latitudes P - poleward of 60 degrees north and south tropical latitudes T - about 25 degrees of the equator continental c - large land masses--dry marine m - the oceans----moist

Air Masses and Fronts Air masses can control the weather for a relatively long time period: from a period of days, to months. Most weather occurs along the periphery of these air masses at boundaries called fronts.
