Local and Global Winds

Front

What are local winds?

Back

Local winds are winds that blow over short distances and are influenced by local geography, such as mountains, valleys, and bodies of water.

Front

What are global winds?

Back

Global winds are large-scale winds that blow across the Earth's surface, driven by the uneven heating of the Earth by the sun.

Front

What causes the Coriolis effect?

Back

The Coriolis effect is caused by the rotation of the Earth, which deflects the path of winds and ocean currents.

Front

What are trade winds?

Back

Trade winds are steady winds that flow from east to west in the tropics, occurring between the equator and 30 degrees latitude.

Front

What are polar easterlies?

Back

Polar easterlies are cold winds that blow from the east near the poles, moving from high pressure areas to low pressure areas.

Front

What are prevailing westerlies?

Back

Prevailing westerlies are winds that blow from west to east in the mid-latitudes, between 30 and 60 degrees latitude.

Front

What is the jet stream?

Back

The jet stream is a narrow band of high-speed winds located near the top of the troposphere, influencing weather patterns.

Front

How does air pressure affect wind movement?

Back

Air moves from areas of high pressure to areas of low pressure, creating wind.

Front

What is the relationship between temperature and air density?

Back

Cold air is more dense than warm air, which affects air pressure and wind patterns.

Front

What are the characteristics of warm air?

Back

Warm air is less dense and exerts less pressure than cold air, causing it to rise.
