According to the three-cell general circulation model, at the equator we would NOT expect to find: the ITCZ. a ridge of high pressure. cumuliform clouds. light winds. heavy showers.

While fly fishing in a mountain stream, you notice that the wind is blowing upstream. From this you might deduce that the wind is a: chinook wind. valley breeze. Santa Ana wind. mountain breeze. katabatic wind.

Which below is usually NOT true concerning a sea breeze circulation? they mainly occur at night they usually occur when the water is cooler than the land they occur when the surface wind blows from the water toward the land can cause clouds to form over the land

Cumulus clouds that appear above isolated mountain peaks are often the result of: katabatic winds. mountain winds. fall winds. Santa Ana winds. valley breezes.

Which of the following conditions favor the development of dust devils? hot, moist days hot, dry days cold, moist days cold, dry days

Which is NOT a characteristic of a thermal low? forms in a region of warm air forms in response to variations in surface air temperature becomes stronger with increasing height lowest pressure is at the center

Surface low pressure becomes best developed over the Asian continent in the: summer. winter. fall. spring.

During the summer along the coast, a sea breeze is usually strongest and best developed: in the afternoon. just after sunrise. just before sunset. just before noon. around midnight.

A dust- or sandstorm that forms along the leading edge of a thunderstorm is a: foehn. haboob. chinook. bora. Santa Ana.

Strong Santa Ana winds develop in Los Angeles during the fall when a __________ pressure center forms to the __________ of Los Angeles over the Great Basin. high, northeast high, southwest low, northeast low, southwest

A katabatic wind is a __________ , __________ wind. cold, upslope warm, upslope cold, downslope warm, downslope

The intertropical convergence zone (ITCZ) is a region where: the polar front meets the subtropical high. northeast trades meet the southeast trades. northeast trades converge with the subtropical high. the Ferrel cell converges with the Hadley cell. polar easterlies converge with the air at the doldrums.

A chinook wall cloud is a: sand storm that marks the leading edge of the chinook. row of intense thunderstorms that bring heavy rain to eastern Colorado. cloud of smoke that marks the advancing edge of the chinook. bank of clouds that form over the mountains and signal the possible onset of a chinook. line of fog that moves over the plains as a chinook advances.

In the three-cell model of the general circulation, areas of surface low pressure should be found at: the equator and the poles. the equator and 30o latitude. the equator and 60o latitude. 30o latitude and 60o latitude. 30o latitude and the poles.

Upwelling occurs along the northern California coast because: winds cause surface waters to move away from the coast. of seismic activity on the ocean bottom. of gravitational attraction between the earth and the moon. water flows from the Atlantic ocean into the Pacific because they are at different levels.

Clouds and precipitation are frequently found on the downwind side of a large lake. This would indicate that the air on the downwind side is: converging and rising. converging and sinking. diverging and sinking. diverging and rising.

Warm southwesterly and cold northeasterly surface winds meet at the: horse latitudes. subpolar low. equatorial low. continental divide.

A sea breeze circulation is caused by __________ differences. humidity temperature altitude surface roughness

The heat from a chinook wind is generated mainly by: compressional heating. sunlight. warm ocean water. friction with the ground. forest fires.

An example of mesoscale motion is: winds on a surface weather map of North America. winds on a 500 mb chart. winds blowing through a city. winds blowing past a chimney. the average wind patterns around the world.

Which of the following associations is most accurate? microscale - chinook wind synoptic scale - sea breeze mesoscale - land breeze planetary scale - lake breeze

The majority of the United States lies within a __________ wind belt. westerly easterly northerly southerly

Which of the following would NOT be associated with a major El Niño event? drought in Australia westerly winds at the equator record fish catch in the ocean off the coasts of Peru and Ecuador warmer than normal ocean water in the eastern tropical Pacific

The name given to a wind system that seasonally changes direction is: katabatic. chinook. mountain breeze. monsoon. diurnal breeze.

Which below does not describe the polar front jet stream? is strongest in winter moves farther south in winter forms near the boundary called the polar front is normally found at a higher elevation than the subtropical jet

On the eastern side of the Rocky Mountains, chinook winds are driest when: clouds form and precipitation falls on the upwind side of the mountains. the air aloft is cold. the sun is shining. the winds are blowing from the east. surface friction is greatest on the downwind side of the mountain.
