Weather Things: Winter

The video explains how the North Pole's tilt affects winter temperatures, the role of the jet stream in creating powerful winter storms, and the formation of lake effect snow. It also covers nor'easters, their impact on the Eastern Seaboard, and the dangers of ice storms. Safety tips for extreme cold conditions, such as preventing hypothermia and frostbite, are provided.

What causes the jet stream to reach its greatest speed during winter?

• The rotation of the Earth

• The tilt of the Earth towards the sun

• The melting of polar ice caps

• The contrast between cold Arctic air and warm equatorial air

What is the primary cause of lake effect snow?

• Warm air rising over mountains

• Cold air moving over large unfrozen lakes

• High humidity in the atmosphere

• Strong ocean currents

How do nor'easters typically form?

• By the melting of snow in the Arctic

• By the rotation of the Earth

• By the collision of two cold fronts

• By drawing warmth and moisture from the Gulf and Atlantic

What is a significant hazard of freezing rain during winter storms?

• Increased humidity

• High temperatures

• Formation of ice on surfaces

• Rapid snowmelt

What does the wind chill temperature indicate?

• The temperature felt by objects like cars

• The actual air temperature

• The temperature of the ground

• How cold the air feels to humans
