Unit 4 - More Hurricanes and Blizzards in NYC? Review Sheet

These flashcards cover key concepts about wind formation, air masses, weather fronts, and weather phenomena from the lecture notes.

What causes wind to form?

Wind is caused by the uneven heating of Earth's surface and pressure differences.

How does air move in relation to pressure?

Air moves from areas of high pressure to low pressure.

What is the Coriolis Effect?

The deflection of wind patterns caused by the rotation of the Earth.

What is an air mass?

An air mass is a large body of air with uniform temperature and humidity conditions.

What are the four types of air masses?

Maritime (m), Continental (c), Polar (P), Tropical (T).

What type of air mass is typically moist?

Maritime (m) air mass.

What is a cold front?

A cold front occurs when a cold air mass pushes into a warm air mass.

What occurs when a warm front moves over a cold air mass?

Typically brings gradual warming, cloud formation, and light precipitation.

What is the difference between a stationary front and an occluded front?

A stationary front occurs when two air masses meet but do not move, while an occluded front forms when a cold front overtakes a warm front.

How is cloud formation related to condensation?

Cloud formation occurs when warm air rises and cools, leading to condensation where water vapor becomes water droplets.

What are the types of precipitation?

Rain, Snow, Sleet, Hail.
