Document Summary
A front is a transition zone between two air masses of different temperature and moisture content (their densities are different) Remember that cold air is more dense than warm air: when cold air and warm air meet, cold air will say close to the earth"s surface, and move the warm air out of the way. We will consider 5 types of fronts: stationary fronts. Dry is more massive water vapor: often results in clouds of vertical development and severe weather, common across the southern great plains. Large storms that can cover half a continent . Mid-latitude cyclones are large traveling atmospheric vorticies with centers of low atmospheric pressure. They derive their existence and energy from air mass differences (density differences). Most of the weather that we experience in the mid-and-high latitude regions of the world are a result of these storms. Mid-latitude cyclones are important in initiating severe weather, and most coastal storms that affect us are mid-latitude cyclones.
