What is caused by the uneven heating of the Earth and its atmosphere?
Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Differences in atmospheric pressure generate winds. At the Equator, the sun warms the water and land more than it does the rest of the globe.
What is the turning of air masses resulting from Earth’s eastward rotation?
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.
What winds are responsible for the movement of much of the weather across the United States and Canada?
Prevailing westerlies in the Northern Hemisphere are responsible for many of the weather movements across the United States and Canada. At about sixty degrees latitude in both hemispheres, the prevailing westerlies join with polar easterlies to reduce upward motion.
What are narrow belts of strong winds called?
Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.
What causes the temperature of the air to change?
The temperature of the air is caused by the combination of air, water, and land working together. Those three factors heat and cool areas at different rates. Temperature also varies by the time of day, the season, or even the year.
Where is the Coriolis effect the strongest?
the poles
The Coriolis force is strongest near the poles, and absent at the Equator.
Which instrument is best used to predict weather changes?
Barometer. First developed by the Italian scientist Evangelista Torricelli in the 17th century, the barometer measures the atmospheric pressure, which helps meteorologists predict weather patterns. These slight changes in the atmosphere’s pressure usually foreshadow changes in the weather.
What is the narrow belt of wind that blows at the top of the troposphere *?
Wind, Atmosphere, and Gases in Enivorment… Chapter 4
| Question | Answer |
|---|---|
| Narrow belts of strong winds at high altitudes which blow near the top f the troposphere | Jet Streams |
| Cool breezes at night aused by differences in heating and cooling rates of land and water | Land Breezes |
| Heat from sun | Solar Radiation |
What are narrow air belts?
Answer Expert Verified. The narrow belts of fast-moving air at the higher levels of the troposphere are called jet streams. The paths of the jet streams can be best described as meandering. Jet streams can start or stop or split or move in the reverse direction at any time.
