Global Winds

Front

What are global winds?

Back

Global winds are large-scale wind patterns that occur in the Earth's atmosphere, driven by the uneven heating of the Earth's surface by the sun.

Front

What causes global winds to blow?

Back

Global winds are primarily caused by the uneven heating of the Earth's surface, which creates differences in air pressure.

Front

What are the prevailing westerlies?

Back

The prevailing westerlies are winds that blow from west to east in the mid-latitudes of the Earth.

Front

What is a barometer used for?

Back

A barometer is an instrument used to measure air pressure.

Front

How do differences in air pressure affect wind speed?

Back

Differences in air pressure cause greater wind speeds; air moves from areas of high pressure to areas of low pressure.

Front

What are trade winds?

Back

Trade winds are steady winds that blow from east to west in the tropics.

Front

What are the doldrums?

Back

The doldrums are regions near the equator where there is little to no wind, often characterized by calm and stagnant air.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as winds, caused by the rotation of the Earth.

Front

How do ocean currents affect global winds?

Back

Ocean currents can influence global winds by altering temperature and humidity levels in the atmosphere.

Front

What is the difference between local winds and global winds?

Back

Local winds are winds that blow over short distances and are influenced by local geography, while global winds are large-scale patterns that affect broader areas.
