Across
- 2. large low-pressure, rotating tropical storm that gets its energy from the evaporation of warm ocean water and the release of heat.
- 6. extended period of below-average temperatures caused by large, high-pressure systems of continental polar or arctic origin.
- 8. classifies hurricanes according to wind speed on a scale ranging from Category 1 to Category 5.
- 9. occurs when powerful, hurricane-force winds drive a mound of ocean water toward shore, where it washes over the land, often causing enormous damage.
- 10. measures the windchill factor by estimating the heat loss from human skin caused by a combination of wind and cold air
- 11. extremely powerful, self-sustaining thunderstorm characterized by intense, rotating updrafts.
- 12. violent downdrafts that are concentrated in a local area.
- 13. calm center of a tropical cyclone that develops when the winds around its center reach at least 120 km/h.
Down
- 1. classifies tornadoes according to their destruction and estimated wind speed on a scale ranging from EF0 to EF5.
- 3. type of thunderstorm in which air rises because of unequal heating of Earth's surface within a single air mass and is most common during the afternoon and evening
- 4. extended period of above-average temperatures caused by large, high-pressure systems that warm by compression and block cooler air masses. period of above-average temperatures caused by large, high-pressure systems that warm by compression and block cooler air masses.
- 5. extended period of well-below-average rainfall, usually caused by shifts in global wind patterns, allowing high-pressure systems to remain for weeks or months over continental areas.
- 7. band where the strongest winds in a hurricane are usually concentrated, surrounding the eye.v
