QuestionAnswer
What is doppler radar? Radar that shows precipitation. The darker the color the more intense the precipitation.
A fast-flowing river of air that forms when two air masses of very different temperatures meet is called a/the jet stream
Air mass thunderstorms occur because of unequal heating of Earth's surface within one air mass. Where would an air mass thunderstorm MOST LIKELY occur? along coastal areas
Rainforests are found near the equator because of the convergence of the trade winds, which causes increased rainfall. What causes the earth's wind patterns? the Coriolis Effect
The local weather station predicts thunder showers caused by a cold mass of air moving in on a warm air mass. This is what happens during an occluded front. How is this shown on a weather map? a purple line where the front is located
A cold air mass from the north is blocked by a warmer air mass from the south. . The air masses stay over the place where they meet. This produces stormy weather. How is this shown on a map? Red and blue intertwined line where the front is located
Which weather condition is NOT associated with cold fronts? A)sudden drop of temperature as front passes B)strong thunderstorms along and ahead of the front C)pressure rising steadily before passing and falling steadily after passing C)pressure rising steadily before passing and falling steadily after passing
Which weather condition is NOT associated with warm fronts? A)warm fronts tend to move slowly B)steady rise of temperature as front passes C)warm fronts typically produce more violent weather than cold fronts C)warm fronts typically produce more violent weather than cold fronts
Which weather condition is NOT associated with cold fronts? A)pressure rising sharply while front passes B)cloud sequence cirrus, status, nimbostratus with steady gentle rains C)front moves at speeds of 20-30 mph, followed by rapid clearing B)cloud sequence cirrus, status, nimbostratus with steady gentle rains
In an El Nino year many rain clouds forms over this warm part of the Pacific Ocean, bringing more _________ than usual in North and South America. Meanwhile, other parts of the world suffer severe ________. rain, drought
During an El Niño winter in the northern United States, we should expect warmer than usual temperatures.
During an El Niño year, we would expect ALL of the following weather conditions in the United States EXCEPT ONE. That would be A)blizzard conditions across the north. B)increased storms in California. C)flooding in the southern states. A)blizzard conditions across the north.
The jet streams follow the contours of low and high pressure areas , which move like waves in the atmosphere across the earth. How does the movement and effects of the polar jet stream change when it is winter in the Northern Hemisphere? The polar jet stream moves south and becomes stronger because the North Pole gets colder but the equator stays the same temperature. The strengthened polar jet stream dips farther south.
As atmospheric gases warm, they rise up higher in the atmosphere. Atmospheric gases cool down, the air will sink. This occurs over and over and air is heated and cooled. What is the main factor that would contribute to this constant movement of the air? density
Which statement best elaborates how air masses would cause severe weather? A)Warm and cold air masses have different densities, when they mix, moisture is released. B)Cold air is denser, when it travels below the warm air, pushing it up storms result. B)Cold air is denser, when it travels below the warm air, pushing it up storms result.
You are watching the weather forecast and the weatherman says that strong thunderstorms and possible tornadoes are likely to form in your area. What would explain the severe weather forecast? Low pressure systems are associated with cold air or moisture rich air
If there is moisture in the atmosphere as the the front comes through, what effect could it have on temperature and weather? The temperature would decrease and there would be a chance of thunderstorms.
