60/100

What type of wind flows from areas of higher pressure to areas of lower pressure?

All winds

What is a jet stream?

A fast, narrow air current in the upper troposphere

Which type of wind is most influenced by the pressure gradient force and Coriolis effect, but not by friction?

Geostrophic wind

What is the name of the wind that typically brings dry, warm air to the west side of the Rockies?

Chinook wind

What causes a monsoon?

Differential heating of land and sea

What causes wind direction to curve instead of moving in a straight line?

Coriolis effect

Which direction does the Coriolis effect deflect winds in the Southern Hemisphere?

To the left

What is the result of surface divergence in a high pressure system?

Sinking air and fair weather

What type of breeze blows from sea to land during the day?

Sea breeze

What is the approximate height of the jet stream?

10–15 km

Which wind pattern is associated with high-pressure systems aloft?

Diverging wind

What best describes the movement of air in a cyclone?

Inward and counterclockwise (Northern Hemisphere)

What is responsible for the rotation of cyclones and anticyclones?

Coriolis effect

What happens when there is convergence at the surface?

Rising motion and potential cloud formation

What local wind is strongest during clear nights in mountainous regions?

Mountain breeze

What causes valley breezes to form?

Daytime heating of slopes

What is the direction of airflow around a low pressure center in the Southern Hemisphere?

Clockwise and inward

Why is surface wind not purely geostrophic?

Due to frictional effects

What term refers to air flowing out from a high pressure system?

Divergence

When air rises in a low pressure area, what typically follows?

Cloud formation and precipitation

What is the main reason surface winds cross isobars instead of flowing parallel?

Friction reduces Coriolis deflection

Which wind system helps balance global heat differences between the equator and poles?

Global circulation

What happens to rising air in a low pressure system?

It expands and cools

What is the source region for Santa Ana winds?

Desert interior

What is the main driver of all wind on Earth?

Solar heating

What type of air movement is associated with surface convergence?

Rising motion

What direction do anticyclones rotate in the Northern Hemisphere?

Clockwise

Which of the following would most likely occur in a region of surface divergence?

Sinking air

What is the key difference between gradient winds and geostrophic winds?

Gradient winds curve around highs and lows

What process causes katabatic winds to form?

Air descending due to cooling on elevated terrain
