Sea Breeze and Thunderstorm Dynamics

The video tutorial explores how horizontal temperature differences drive vertical circulations, which can support thunderstorm development. It explains the diurnal heating cycle's impact on land and sea temperatures, leading to sea breezes during the day and land breezes at night. The tutorial also covers how mountain slopes affect heating and circulations, contributing to thunderstorm formation. Finally, it discusses the role of small-scale circulations in influencing storm development and behavior.

What role do horizontal temperature differences play in weather phenomena?

• They lead to ocean currents.

• They drive vertical circulations that support thunderstorms.

• They cause earthquakes.

• They have no significant impact.

Why do land areas heat up faster than water areas during the day?

• Water reflects more sunlight than land.

• Land has a higher heat capacity than water.

• Water absorbs more sunlight than land.

• Land has a lower heat capacity than water.

What is a sea breeze and how does it form?

• A cool, dense air mass moving inland from the water.

• A warm, dense air mass moving inland from the water.

• A warm wind from the desert.

• A cool wind from the mountains.

How does the sea breeze boundary affect thunderstorm development?

• It prevents thunderstorms from forming.

• It creates a zone of ascent that can lead to thunderstorms.

• It dissipates existing thunderstorms.

• It has no effect on thunderstorms.

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

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

• Sea breeze is associated with higher buoyancy during the day.

• Land breeze is stronger than sea breeze.

• Land breeze occurs only in winter.

Why is thunderstorm development less likely over water at night?

• There is more buoyancy over water at night.

• Water heats up faster than land.

• There is less buoyancy over water at night.

• Water cools down faster than land.

How do mountains influence thunderstorm development?

• They create density differences that drive upslope flows.

• They have no effect on weather patterns.

• They block all storm activity.

• They only affect storms during winter.

What is an anabatic flow?

• A downslope flow at night.

• A flow that occurs only in deserts.

• An upslope flow during the day.

• A horizontal flow over flat land.

What happens to storms that move off mountains?

• They are unaffected by the terrain.

• They intensify regardless of conditions.

• They encounter higher inhibition and may dissipate.

• They always dissipate.

What is the main factor driving the ascent necessary for thunderstorm development?

• Density differences due to differential heating

• Temperature alone

• Wind speed

• Humidity levels
