Across
- 3. A period of abnormally dry weather sufficiently long enough to cause serious effects on agriculture and other activities in the affected area.
- 5. A high cloud composed of ice crystals in the form of thin, white, featherlike clouds in patches, filaments, or narrow bands.
- 7. The degree of hotness or coldness of a substance as measured by a thermometer. It is also a measure of the average speed or kinetic energy of the atoms and molecules in a substance.
- 10. The cumulative force exerted on any surface by the molecules composing air.
- 13. Solid precipitation in the form of chunks or balls of ice with diameters greater than 5 mm. The stones fall from cumulonimbus clouds.
- 14. A visible electrical discharge produced by thunderstorms.
- 15. Solid precipitation in the form of minute ice flakes that occur below 0ÂșC.
Down
- 1. The transition zone between two distinct air masses.
- 2. A cloud in the form of individual, detached domes or towers that are usually dense and well defined. It has a flat base with a bulging upper part that often resembles cauliflower. Cumulus clouds of fair weather are called cumulus humilis. Those that exhibit much vertical growth are called cumulus congestur or towering cumulus.
- 4. The study of the atmosphere and atmospheric phenomena as well as the atmosphere's interaction with the earth's surface, oceans, and life in general.
- 6. An intense, rotating column of air that protrudes from a cumulonimbus cloud in the shape of a funnel or a rope and touches the ground. (See Funnel cloud.)
- 8. The state of the atmosphere in terms of such variables as temperature, cloudiness, precipitation, and radiation.
- 9. A low, gray cloud layer with a rather uniform base whose precipitation is most commonly drizzle.
- 11. Precipitation in the form of liquid water drops that have diameters greater than that of drizzle.
- 12. The accumulation of daily and seasonal weather events over a long period of time. A description of aggregate weather conditions; the sum of all statistical weather information that helps describe a place or region.
