Understanding Global Winds

The video tutorial explains global wind patterns, focusing on Hadley, Ferrel, and polar cells. It describes how warm air rises at the equator, creating low pressure, while cold air sinks at the poles, creating high pressure. The Coriolis effect causes winds to deflect, forming trade winds, westerlies, and polar easterlies. The video also covers subtropical highs, equatorial lows, and horse latitudes, providing a comprehensive overview of global wind systems.

What happens to warm air at the equator?

• It sinks and creates high pressure.

• It rises and creates low pressure.

• It moves horizontally and creates no pressure change.

• It cools and creates high pressure.

What is the name of the high-pressure system created as air sinks at 30 degrees latitude?

• Polar High

• Mid-Latitude Low

• Equatorial Low

• Subtropical High

Which effect causes the deflection of wind to the right in the northern hemisphere?

• Solar Influence

• Gravitational Pull

• Magnetic Effect

• Coriolis Effect

What are winds called that move from east to west in the polar regions?

• Westerlies

• Trade Winds

• Polar Easterlies

• Subtropical Winds

In the southern hemisphere, how do winds deflect?

• To the right

• Upward

• Downward

• To the left

What are the trade winds known for in terms of direction?

• Moving from west to east

• Moving from south to north

• Moving from east to west

• Moving from north to south

What is the term for the region at 30 degrees latitude with little wind?

• Doldrums

• Subtropical Ridge

• Polar Front

• Horse Latitudes

What is the equatorial low sometimes referred to as?

• Doldrums

• Horse Latitudes

• Polar Front

• Subtropical Ridge

Which winds blow from the northeast in the northern hemisphere?

• Polar Easterlies

• Westerlies

• Subtropical Winds

• Trade Winds

What is the primary direction of the westerlies?

• East to west

• South to north

• North to south

• West to east
