Across
- 1. The study of the Earth's atmosphere.
- 5. The effect that the Earth's rotation has on objects on Earth such as prevailing winds and ocean currents.
- 9. A meteorological instrument used to measure the atmospheric pressure.
- 10. Precipitation that falls to the ground in the form of liquid droplets.
- 12. A storm that produces thunder and lighting. It usually also generates high winds and rain.
- 13. This is a type of precipitation in the form of lumps of ice. It is formed in the updrafts of large thunderstorms.
- 15. A measurement of the amount of water vapor in the air.
- 16. A tropical cyclone that formed in Southeast Asia.
- 18. A narrow band of strong winds in the upper atmosphere.
- 21. A large rotating storm with high speed winds that forms over warm waters in the ocean.
- 24. A flash flood is a flood that happens quickly (just a few hours), usually due to heavy rain.
- 26. A period of warming in the water of the Pacific Ocean near the equator.
- 28. Frozen precipitation that falls to the ground when water vapor is turned into ice.
- 29. Drops of water that comes from water vapor condensing on objects near the ground.
- 30. The gas phase of water.
- 33. A pattern of weather in a region as measured over a long period of time.
- 34. A snow storm that has winds of 35 miles per hour or more.
- 35. A line on a weather map that represents a given barometric pressure. All points on the line, or isobar, have the same barometric pressure.
- 38. A rise in the sea level at the coastline due to a huge storm such as a hurricane.
Down
- 2. A region with low air pressure and warm, moist air.
- 3. A cloud that is low to the ground and makes it hard to see.
- 4. A region with high air pressure and cool, dry air.
- 6. A front where cold air is replacing warm air.
- 7. Winds that blow fairly consistently in the same direction over a particular area of the Earth's surface.
- 8. The movement or flow of air on a large scale.
- 11. A meteorological instrument used to measure wind speed.
- 14. The center of a tropical cyclone or hurricane where there is low air pressure, no clouds, and calm winds.
- 17. A sudden increase in sustained winds over a short time period.
- 19. This occurs when rain falls on objects and then freezes. The weight of the ice can cause damage, causing trees and power lines to fall.
- 20. A rotating column of air with high wind speeds that makes contact with the ground.
- 22. A measure of speed most often used in the ocean. One knot equals 1.15 miles per hour.
- 23. A tropical cyclone that formed in the North Atlantic Ocean.
- 25. The boundary between low and high air pressure systems.
- 27. When the waters near the equator in the Pacific Ocean cool down.
- 31. Precipitation occurs when the condensation of water vapor causes it to fall to the Earth's surface. It can occur in many forms including rain, sleet, snow, and hail.
- 32. An area of low atmospheric pressure that is surrounded by clouds and precipitation.
- 33. A mass of tiny water droplets floating in the atmosphere that we can see from the ground.
- 36. A front where warm air is replacing cold air.
- 37. A very large and long-lived thunderstorm.
