- 2. the general weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a longer period of time
- 5. a cloud of a class characterized by a gray, horizontal layer with a uniform base, found usually below 8000 feet (2400 meters).
- 6. pressure pressure resulting in stormy weather
- 7. a cloud of a class characterized by thin white filaments or narrow bands and a composition of ice crystals: of high altitude, about 20,000–40,000 feet (6000–12,000 meters).
- 8. very hot and humid
- 11. front a front between warm and cold air masses that is moving very slowly or not at all; brings longer periods of rain
- 17. any instrument for measuring the speed of wind
- 18. the angular distance north or south from the equator of a point on the earth's surface, measured on the meridian of the point.
- 19. the region of the upper atmosphere extending upward from the tropopause to about 30 miles (50 km) above the earth, characterized by little vertical change in temperature; jets and ozone are found here
- 22. front a composite front formed when a cold front overtakes a warm front and forces it aloft; creates the most severe storms
- 23. gauge an instrument for measuring rainfall
- 25. effect an atmospheric heating phenomenon, caused by short-wave solar radiation being readily transmitted inward through the earth's atmosphere but longer-wavelength heat radiation less readily transmitted outward, owing to its absorption by atmospheric carbon dioxide, water vapor, methane, and other gases; thus, the rising level of carbon dioxide is viewed with concern.
- 26. the highest region of the atmosphere, where the air density is so low that a fast-moving air molecule is more than 50 percent likely to escape from the atmosphere instead of hitting other molecules.
- 28. layer located in the stratosphere and is composed of gas made of 3 oxygen atoms (O3); Absorbs 99% of suns harmful UVB rays
- 29. stream Any of the high-speed, high-altitude air currents that circle the Earth in a westerly direction.
- 30. pressure pressure resulting in clear weather
- 32. a system of colloidal particles dispersed in a gas; smoke or fog.
- 33. The reflectiveness of a surface. Black absorbs all colors while white reflects all colors.
Down
- 1. the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc.
- 3. warming an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect
- 4. front a transition zone between a mass of warm air and the colder air it is replacing; brings drizzle or snow flurries
- 7. a cloud of a class indicative of thunderstorm conditions, characterized by large, dense towers that often reach altitudes of 30,000 feet (9000 meters) or more, cumuliform except for their tops, which appear fibrous because of the presence of ice crystals: occurs as a single cloud or as a group with merged bases and separate tops.
- 8. the lowest layer of the atmosphere, 6 miles (10 km) high in some areas and as much as 12 miles (20 km) high in others, within which there is a steady drop in temperature with increasing altitude and within which nearly all cloud formations occur and weath
- 9. the region of the upper atmosphere in which temperature increases continuously with altitude, encompassing essentially all of the atmosphere above the mesosphere; where find the northern lights and space shuttles
- 10. exposure to the sun's rays; the amount of solar radiation reaching a given area
- 12. pressure the force exerted by air, whether compressed or unconfined, on any surface in contact with it.
- 13. a line on a weather map or chart connecting points having equal temperature.
- 14. a cloud of a class characterized by dense individual elements in the form of puffs, mounds, or towers, with flat bases and tops that often resemble cauliflower: as such clouds develop vertically, they form cumulonimbus.
- 15. any instrument that measures atmospheric pressure.
- 16. effect the apparent deflection of a body in motion with respect to the earth, as seen by an observer on the earth, attributed to a fictitious force but actually caused by the rotation of the earth and appearing as a deflection to the right in the Northern Hemisphere and a deflection to the left in the Southern Hemisphere.
- 20. Zone the part of the earth's surface lying between the tropic of Cancer and the Arctic Circle in the Northern Hemisphere or between the tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere, and characterized by having a climate that is warm in the summer, cold in the winter, and moderate in the spring and fall.
- 21. the gaseous envelope surrounding the earth; the air.
- 24. vane any instrument for measuring the direction of wind
- 27. an elevated region; plateau
- 31. front the zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer; brings storms
- 34. Niño a warm ocean current of variable intensity that develops after late December along the coast of Ecuador and Peru and sometimes causes catastrophic weather conditions.
