Weather Phenomena and Systems

When a weather front passes through an area with high humidity, which weather phenomenon is most likely to occur?

• A. A sudden drop in temperature with light drizzle

• B. Increased cloud cover with potential thunderstorms

• C. Clear skies with an abrupt warming trend

• D. A steady, calm day with minimal wind

Which type of pressure system is most commonly associated with clear, sunny weather?

• Low-pressure system

• High-pressure system

• Occluded system

• Stationary front

When a cold air mass meets a warm air mass, what typically happens to the warm air?

• A. It sinks beneath the cold air

• B. It remains stationary

• C. It is forced to rise over the cold air

• D. It mixes evenly with the cold air

Which cloud type is most often linked with the development of severe thunderstorms?

• Stratus

• Cumulonimbus

• Altostratus

• Cirrus

How do sea breezes affect the temperature along coastal areas during the daytime?

• They significantly raise temperatures

• They help to cool the coastal regions

• They have no noticeable effect on temperature

• They cause sudden temperature drops at night

What is the primary mechanism by which the sun’s energy reaches Earth?

• Conduction

• Convection

• Radiation

• Evaporation

Land breezes occur at night primarily because:

• The ocean warms up faster than the land

• Land loses heat more quickly than water

• Air pressure is higher over the ocean

• Winds always reverse direction at night

Which best describes an occluded front?

• A. A boundary where warm air slides over retreating cold air

• B. A collision between two cold air masses

Analyze the potential outcomes when a stationary front lingers over a region for several days. Which combination of conditions is most likely?

• Persistent, moderate rainfall, minimal temperature change, and extended cloudiness

• Rapid swings in temperature with sporadic, brief showers

• Consistently warm weather interspersed with isolated thunderstorms

• A quick onset of severe storms followed by an abrupt clearing of skies

What effect does the Coriolis force have on moving air?

• It reverses wind direction

• It causes winds to deflect relative to Earth’s surface

• It significantly increases wind speeds

• It neutralizes pressure differences between regions
