Weather Patterns and Phenomena

The video explores the power of air in influencing weather, focusing on air masses, fronts, and pressure zones. It details how different air masses affect Korea's climate and explains the formation and impact of various weather fronts. The video also covers reading weather maps, understanding pressure zones, and the characteristics of tropical depressions like typhoons. It concludes with a preview of the next topic on atmospheric circulation.

What is an air mass?

• A type of cloud formation

• A small pocket of air with varying temperature

• A weather phenomenon caused by wind

• A large body of air with uniform temperature and humidity

Which air mass affects Korea during the winter?

• Northern Pacific High

• Okhotsk High

• Siberian Express

What is the Foehn Effect?

• A cold wind blowing from the sea

• A humid wind causing rain

• A wind pattern causing snow

• A dry, warm wind descending a mountain slope

What happens when a cold front passes over land?

• Air temperatures rise and stratus clouds form

• Air temperatures drop and cumulus clouds form

• Air pressure drops and rain occurs

• Air pressure remains constant

What is an occluded front?

• A front causing heavy snowfall

• A front where cold air meets warm air

• A front where a cold front overtakes a warm front

• A stationary front with no movement

How do high pressure zones affect weather?

• They lead to clear weather

• They cause hurricanes

• They cause cloudy and rainy weather

• They result in thunderstorms

What is the main characteristic of a migratory high pressure zone?

• It remains stationary

• It moves with westerly winds

• It causes heavy rainfall

• It forms over the ocean

What is a typhoon's turning point?

• The point where it dissipates

• The point where it reaches maximum strength

• The point where it changes direction

• The point where it forms

What causes a typhoon surge?

• High air pressure

• Low air pressure and winds

• High humidity levels

• Cold ocean temperatures

What happens to a typhoon when it makes landfall?

• It loses kinetic energy

• It increases in size
