1. The current state of the atmosphere in any certain place. Happening now!
2. A measure of how much water vapor is in the air.
3. A type of weather front where an air mass gets separated from the ground by a fast-moving cold air mass, resulting in heavy rain.
4. Winds that blow mostly in one direction, moving air masses.
5. A type of weather front where cold air masses overtake warm air masses.
