Climate/ Weather Unit Review Flashcards
Weather is the state of the atmosphere at a specific time and place, determined by factors that include air pressure, temperature, wind, and the amount of moisture in the air.

At the same latitude, the climate is colder in the mountains than at sea level. When radiation from the Sun is absorbed by Earth’s surface, it heats the land. Heat from the Earth then heats the atmosphere. In the mountains, the air has fewer molecules to absorb this heat. This is because Earth’s atmosphere gets thinner at higher altitudes. Therefore, air pressure is greater at sea level and less in the mountains.

Humidity is the amount of water vapor present in the air. And relative humidity is a measure of the amount of water vapor present in the air compared to the amount needed for saturation at a specific temperature. Remember that air that is saturated cannot hold any more water vapor, versus unsaturated air that can hold more water vapor.

Know that if you are standing at the equator, air appears to be deflected to the right in the northern hemisphere, while those in the southern hemisphere are deflected to the left. The Coriolis effect causes this.

Meteorologists use data from so many sources in creating a weather forecast because predicting the weather can be difficult due to the fact atmospheric conditions can rapidly change, making forecasting the weather very unpredictable. Meteorologists use so many sources to be as accurate as possible.

The sun can influence weather by:
evaporating water in the atmosphere to create clouds.
heating air in the atmosphere.
heating water on Earth.

Earth’s rotation causes low-pressure winds to swirl in a counter-clockwise direction.

Climate is the average weather pattern in an area over a long period of time, generally 30 or more years (determined mainly by temperature, humidity, precipitation, and vegetation.)
