| fog | when air is cooled to its dew point near the ground, it forms a stratus cloud |
| front | a boundary between 2 air masses of different density, moisture, or temperature |
| humidity | the amount of water vapor present in the air |
| hurricane | a large swirling, low-pressure system that forms over the warm Atlantic Ocean |
| isobar | a line drawn to connect points of equal atmospheric pressure |
| isotherm | a line that connects points of equal temperature |
| meteorologist | a person who studies the weather |
| precipitation | water falling from clouds |
| relative humidity | a measure of the amount of water vapor present in the air compared to the amount needed for saturation at the specific temperature |
| station model | shows the weather conditions at a specific location on Earth's surface |
| tornado | is a violently rotating column of air in contact with the ground |
| weather | refers to the study of the atmosphere at a specific time & place.Describes conditions such as air pressure, wimd,temperature & the amount of moisture in the air. |
| air mass | a large body of air that has properties similar to the part of Earth's surface over which it developes |
| blizzard | a winter storm that the winds are 56km/h, the temperature is low, the visibility is less than 400m in falling or blowing snow. The conditions persist for 3 hrs. or more |
| dew point | the temperature at which air is saturated and condensation forms ( changes with the amount of water vapor in the air) |
