Clouds
Collection of small water droplets or ice crystals that are suspended in the air.
What are clouds?
When air masses move it takes the weather characteristics.
How do air masses affect weather?
Involves evaporation, condensation, precipitation.
What steps are involved in the water cycle?
Measure of how hot or cold something is.
What is temperature?
Forms when water vapor cools to its dew point.
How do clouds form?
Pressure systems affect temperature and humidity.
How do pressure systems affect us?
The continuous movement of water between the atmosphere, the land, the oceans, and living things.
What is the water cycle?
The amount of water vapor in the air compared to the amount of water vapor needed to reach saturation.
What is relative humidity?
The precipitation from clouds determines the climate and the type of clouds reflect different amounts of sun in the atmosphere.
How do clouds affect the climate?
Global winds affect the temperature.
How do global winds affect local weather?
Change of state from a liquid to a gas.
What is evaporation?
Force of air molecules pushing on an area.
What is air pressure?
Frontal lifting occurs when a warm air mass rises over a cold air mass.
When does frontal lifting occur?
Can pull cold air down from Canada to U.S and push warm air up toward Canada.
How do jet streams affect weather
Rain, sleet, hail, or snow are an example of it.
What are examples of precipitation?
A measure of transparency of the atmosphere.
What is visibility?
Frontal and orographic lifting cool air air enough to form clouds.
What processes cool air enough to form clouds?
Bring heavy rain or snow and cold weather.
What are cold fronts?
Rain is the most common form of it.
What is the most common form of precipitation?
Measure with 3 or 4 known landmarks.
How is visibility measured?
