Below are sample questions representative of the exercises included on this worksheet and related 9.126 Air Masses and Fronts skill assessments:

Problem 1Difficulty: Mastery

Which observation pattern best supports drawing a cold front rather than just a broad temperature gradient?

AA slow temperature change across hundreds of kilometers with no wind or pressure shift

BA cloud-free high-pressure center with uniform station observations

CA narrow zone with sharp temperature and dew-point drops, wind shift, pressure trough, and showers

DOne warm city next to another warm city with similar humidity

Solution & Explanation:A cold front is a narrow air-mass boundary with multiple supporting signals, not merely a gradual temperature difference over a large area.

Problem 2Difficulty: Mastery

A front is forecast to move east. City A west of the front has 13 degrees C air with dew point 5 degrees C. City B east of the front has 27 degrees C air with dew point 21 degrees C. Which forecast is best?

ACity A will become warmer and more humid because it is behind the cold air.

BCity B may experience frontal lifting before cooler drier air arrives.

CCity B is already behind the front because it is warmer.

DBoth cities will keep identical weather because fronts do not move.

Solution & Explanation:With cooler drier air west of an east-moving boundary and warm humid air east of it, City B is ahead of a likely cold front and may experience lifting before cooler air arrives.

Problem 3Difficulty: Mastery

Use the regional map. City X is west of a cold front, City Y is east of the cold front but south of the warm front, and City Z is north of the warm front. Which city is most likely in warm, humid mT air at the surface?

ACity Y

BNo city can be in mT air near fronts

CCity X

DCity Z

Solution & Explanation:The warm sector between the cold front and warm front is usually warm and humid when maritime tropical air is present, so City Y best fits.
