| isobar | a line on a map that connects places that have the same atmospheric pressure |
| jet stream | high altitude, fast-moving wind |
| high pressure center | a high pressure center area created by sinking cold air |
| low pressure center | a low pressure area created by rising warm air |
| dew point | the temp at which more water condenses than evaporates |
| weather | the condition of the atmosphere that is affected by the temp, pressure, and water |
| tornado | a system of rotating winds around a pressure center smaller than a hurricane, but with faster wind |
| hurricane | a tropical cyclone with wind speeds of at least 74 mph |
| wind | horizontal movement of air that happens as a result of pressure difference |
