Weather

4. A long-lasting storm that starts over the warm surface of the ocean and has winds of 119 km or higher.
6. An atmospheric condition of high central pressure, with currents flowing outward.
9. The boundary where unlike air masses meet but do not easily mix.
12. Front When a warm air mass and a cold air mass meet and neither can move the other.
13. Lines on a map joining places that have the same air pressure.
14. clouds Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
15. A scientist who studies weather and tries to predict it.
16. The amount of water vapor in the air
17. measuring instrument for measuring temperature
21. rotation of air around a high pressure center in the opposite direction of Earth's rotation
22. humidity ratio of the amount of water vapor in the air to the actual amount of water vapor needed to reach saturation at a given temperature
23. Floods Sudden, violent floods that occur shortly after a storm.
24. Front When a rapidly moving cold air mass overtakes a slow-moving warm air mass.
27. an instrument that measures atmospheric pressure

1. a booming or crashing noise caused by air expanding along the path of a bolt of lightning
2. cloud puffy , white clouds that tend to have flat bottoms, usually indicate fair weather
3. water that falls from the atmosphere to the Earth as rain,sleet , or snow
5. Clouds that form in layers. Stratus clouds cover large areas and usually block out the sun.
6. mass a large body of air where temperature and moisture content are constant throughout
7. rapid inward circulation of air masses about a low-pressure center
8. A violent disturbance in the atmosphere.
10. Change in state from a gas to a liquid
11. clouds thin, feathery white clouds which format high altitudes
13. Lines on a map joining places with the same temperature.
18. A funnel shaped cloud that touches Earth's 3. surface.
19. Front Where a warm air mass is caught between two cooler air masses.
20. the flash of light that accompanies an electric discharge in the atmosphere (or something resembling such a flash) from opposite charges
21. a gauge for recording the speed and direction of wind
25. Front When a warm air mass overtakes a cold air mass.
26. Short term fluctuations (days, weeks) in temperature, precipitation, and humidity resulting from rapidly forming and decaying weather systems
