Weather

1. a natural movement of air, sometimes with considerable force from an area of high density and pressure to an area of low density and pressure
5. A body of air extending over a large area (1,000 miles or more) that develops and retains specific characteristics of pressure, temperature, and humidity
6. Severe or dangerous weather phenomena that threaten life and property
8. An air mass with greater atmospheric pressure than the surrounding air masses; air moves away from the center of the high pressure, traveling in a clockwise direction in the northern hemisphere and a counterclockwise direction in the southern hemisphere
9. A narrow zone of strong winds in the upper level of the atmosphere
10. An air mass with less atmospheric pressure than the surrounding air masses; air moves toward the area of low pressure, traveling in a counterclockwise direction in the northern hemisphere and a clockwise direction in the southern hemisphere

1. Similar weather for a certain number of days
2. Winds that act as a heat transfer system due to the unequal heating of Earth’s surface
3. Extreme weather events such as floods, hurricanes, and tornadoes; classified by the extent and intensity of their impact on the ecosystem
4. A system for bouncing electromagnetic waves off objects to locate them; used to track weather patterns
7. Directional movements of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences
