Winds, dew point and Humidity Flashcard

Front

What is orographic lifting?

Back

Orographic lifting occurs when an air mass is forced to rise over a topographic barrier, such as a mountain.

Front

What is relative humidity?

Back

Relative humidity is the amount of moisture in the air compared to the maximum amount of moisture the air can hold at a given temperature, expressed as a percentage.

Front

What is a sea breeze?

Back

A sea breeze is a wind that blows from the sea to the land, typically occurring during the day when the land heats up faster than the water.

Front

What is an anemometer used for?

Back

An anemometer is a weather instrument used to measure wind speed.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the phenomenon where the rotation of the Earth causes moving air and water to turn and twist rather than move in a straight line.

Front

What is convective lifting?

Back

Convective lifting occurs when warm air rises due to its lower density compared to the surrounding cooler air.

Front

What is the dew point?

Back

The dew point is the temperature at which air becomes saturated with moisture and water vapor begins to condense into liquid.

Front

What is a land breeze?

Back

A land breeze is a wind that blows from the land to the sea, typically occurring at night when the land cools faster than the water.

Front

What is a psychrometer?

Back

A psychrometer is a device used to measure the relative humidity of the air by comparing the temperatures of a dry bulb and a wet bulb.

Front

What are trade winds?

Back

Trade winds are steady winds that blow from east to west in the tropics, caused by the Earth's rotation and the uneven heating of the Earth.
