Coriolis Effect and Wind Dynamics

The video explains how air movement is influenced by pressure differences, Coriolis force, and geostrophic flow. It covers the concepts of high and low pressure, pressure gradient force, and how these affect wind direction and strength. The Coriolis force, caused by Earth's rotation, deflects winds differently in each hemisphere. Geostrophic flow occurs when pressure gradient and Coriolis forces balance, causing winds to move parallel to isobars. The video also discusses the rotation of pressure systems in different hemispheres and concludes with the importance of understanding these concepts.

What causes wind to move from high pressure areas to low pressure areas?

• Humidity levels

• Pressure gradient force

• Temperature differences

• Coriolis effect

How can you determine the strength of the wind using a weather map?

• By looking at the temperature

• By observing the distance between isobars

• By measuring the altitude

• By checking the humidity levels

Where is the Coriolis force strongest?

• At the poles

• In the mid-latitudes

• At the equator

• In the tropics

In which direction do winds deflect in the southern hemisphere due to the Coriolis effect?

• To the right

• To the left

• Upwards

• Downwards

What is geostrophic flow?

• Wind moving in a circular pattern

• Wind moving vertically

• Wind moving parallel to isobars

• Wind moving perpendicular to isobars

Where does geostrophic flow typically occur?

• Near the Earth's surface

• In the upper atmosphere and over oceans

• In urban areas

• In mountainous regions

How do low pressure systems rotate in the northern hemisphere?

• Counterclockwise

• Horizontally

• Clockwise

• Vertically

According to the Vise Balance Law, where is the high pressure located if you stand with your back to a geostrophic wind in the southern hemisphere?

• Behind you

• In front of you

• On your left

• On your right

What is the main cause of the deflection of wind in different hemispheres?

• Altitude changes

• Humidity levels

• Temperature differences

• Earth's rotation

What is the effect of the Coriolis force on wind direction in the northern hemisphere?

• Increases wind speed

• Stops wind movement

• Deflects wind to the right

• Deflects wind to the left
