Meteorology
2nd test
| Term | Definition |
|---|---|
| Stratocumulus | this cloud has low, lumpy rounded masses and is generally a low cloud. Predominantly statisform in nature. Often with blue skies. In which Crepuscular rays sometimes appear |
| Cumulonimbus | a vertically developed cloud that is exceptionally dense, often with a top in the shape of an anvil. |
| nimbostraus | this cloud is not accompanied by lighting, thunder or hail. It is a dark gray cloud characterized by or less continuously falling precipitation. |
| cirrostratus | these clouds frequently cover the entire sky and often produce a halo, they are high sheetlike clouds composed of ice crystals. |
| altostratus | a middle cloud composed f gray or bluis sheets of layers of uniform appearances in the thinner region, the sun or moon usually appear dimly visible. |
| cumulus | a low cloud that often looks like a floating cotton can contain some ice crystal but in general are made up of water droplets. very common in summer |
| altocumulus | a middle cloud in which they do not take the entire sky.these clouds often appear as little castles in the sky. precipitation can occur but rarely does. the bigger puffs are a big give a away that these are not cirrocumulus. |
| stratus | a low cloud that usually covers the entire sky. gray in color, can produce occasional drizzle. heavy rain rarely falls from this |
| cirrus | a high cloud composed of ice crystals in the form of thin, white, feather like clouds in patches, filament or narrow bands. often produces a mare tail |
| cumulonimbus | the cloud with the greatest vertical growth |
| hail is usually associated with what cloud | cumulonimbus |
| on a cold calm autumn morning, the formation of a fog above a relative warm lake will most likely be | steam fog |
| condensation nuclei may be | salt from the ocean, nitric particles, particles of dust,smoke from forest fires. |
| cirrus clouds are composed primarily of | ice particles |
| fog that most often forms as warm rain falls into a cold layer of surface are is called | evaporation fog |
| on humid days, salt in saltshakers sometimes becomes moist and no longer pours out easily. This salt can be described as | hygroscopic |
| particles that serve as surface on which water vapor may condense are called | condensation nuclei |
| the blue color of the sky is due to | selective scattering of visible lights by air molecules. |
| red sunsets, blue moon, and milky white skies are mainly the result of | refraction |
| if they form colliflowring heads they are called | towering cumulus or cumulus congestion |
| condensation are important in the atmosphere because | they make it easier for condensation to occur in the atmosphere |
| geostationary satellites | orbit the earth once a day |
| secondary rainbows occur when | two internal reflections of light occur in raindrops |
| dew is most likely to form on | clear, calm nights |
| the bending of light that occurs when it enters and passes through a substance of different density | refraction |
| when radiation fog "burns off" the fog tends to dissipate from | the bottom up |
| which of the following will you most likely observe over snow-covered ground in the winter; shimmering, superior mirages, crepuscular rays, sun pillars? | superior mirages |
| the cooling of the ground to produce dew is mainly the result of | raditional cooling |
| a colored ring that appears around the shadow of an aircraft is called | glory |
| on an infrared satellite image, low warm clouds appear________ and high, cold clouds appear_____ | gray, white |
| the process that produces crepuscular rays in the atmosphere is called | scattering |
| because of atmospheric refraction a star seen near the earth's horizon is actually | lower than it appears |
| polar orbiting sattelites | on each successive orbit view an area to the west of the previous orbit |
| radiation fog typically forms on | clear, calm nights |
| sunlight reflecting off ice crystals produces which of the following? | sun pillars |
| halos are cause by | refraction of light passing through ice crystals |
| if the earth did not have an atmosphere, the sky would appear______ during the day | black |
| the fog that form along the pacific coastline of north america is mainly which type? | advection fog |
| a mirage is caused | by the bending of the light by air different densities. |
| on a foggy night it is difficult to see the road when the beam lights are on because of ________of light by the fog | scattering |
| The two people see a rain shower. Who will see the rainbow? | the one behind the storm. Looking opposite from the sun |
| Which of the following are capable of producing a red sunrise or sunset? | volcanic ash, small suspended dust particles, small suspended salt particles |
| radiation fog forms best on a | clear winter night with a slight breeze |
| which clouds are most always composed of ice crystals? | cirrus, cirrostratus, cirrocumulus |
| stars are not visible during the day because | the scattered light coming from the sky is to bright to be able to see the weaker light |
| an atmospheric phenomenon that causes objects to appear inverted is called | an inferior mirage |
| which of the following are caused by the bending of lights through ice crystals? | halos and sundogs |
| beams of light that shine downward through beakers or holes in clouds are called | crepuscular rays |
| when you see a layer of wet haze you know that the relative humidity is | 75% or more, higroscopil nuclei are present,condensation is occurring on some nuclei |
| water vapor is | a gas |
| the amount of water vapor in the air | humidity |
| ice to vapor | sublimation |
| vapor to ice | deposition |
| vapor to liquid | condensation |
| the total number of molecules escaping a liquid is in balance with the ones returning | saturation |
| water vapor that is added to the atmosphere | transpiration |
| mass of water vapor/ volume of air | absolute humidity |
| mass of water vapor/ total mass of air | specific humidity |
| mass of water vapor / mass of dry air | mix ratio |
| the saturation vapor pressures depends primarly on | temperature |
| how close is the air to being saturated | relative humidity |
| lowest temperature that can be reached by evaporating water into the air | wet bulb temperature |
| the temperature at which the air would have to be cooled for saturation to occur | dew point |
