What is air mass
200
this is where two masses of air collide one another.
What is a front
200

500
these winds are important for north america and travel from west to east from 30 deg to 60 deg lattitudes
What is prevailing westerlies
500
this is when a warm air mass is stuck between two cooler air masses, pushing the warm air mass upwards, leading to further cooling and precipitation
