The Nature of Weather: Local Winds

The video explains how wind patterns can form on both global and local levels. It provides examples of local winds, such as sea breezes and land breezes. Sea breezes occur when cooler ocean air replaces warm air over the land, while land breezes happen at night when the air over the ocean is warmer than the land. These examples illustrate the dynamic nature of local wind patterns.

What are the two levels at which wind patterns can form?

• Global and local

• Global and regional

• Continental and regional

• Local and continental

In which direction does a sea breeze blow?

• From the south to the north

• From the ocean to the land

• From the north to the south

• From the land to the ocean

What causes a sea breeze to form?

• Warm air over the land moves towards the ocean

• Warm air over the ocean rises and is replaced by cooler land air

• Cooler ocean air replaces warm air over the land

• Cooler land air moves towards the ocean

What happens to the air over the ocean at night during a land breeze?

• It becomes cooler than the air over the land

• It becomes warmer than the air over the land

• It remains the same temperature as the air over the land

• It becomes colder than the air over the land

What is the main difference between a sea breeze and a land breeze?

• Sea breeze involves cool air from the land, land breeze involves cool air from the ocean

• Sea breeze occurs during the day, land breeze at night

• Sea breeze involves warm air from the land, land breeze involves warm air from the ocean

• Sea breeze occurs at night, land breeze during the day
