What is relative humidity?
how much water vapor is in the air compared to how much the air can hold
What is a continental air mass?
air mass over land
temperature changes (air rises) - see clouds, rain, and precipitation
What is a weather forecast?
A prediction about future weather
What affects weather?
The sun, landforms, and bodies of water
What is saturation?
when the air holds all the water it can at a specific temperature
What is a maritime air mass?
Air mass over water
Describe a high pressure system
sinking air - clear skies, sunny weather
Why can we only predict weather?
Because scientist make an educated guess based on the temp, satellite imgs, humidity, and other factors which can all change
NO, the earth doesn't heat the same all over. This makes different temps and air masses
How is relative humidity given?
As a percentage
Which types of air mass are tropical?
warm air masses
When are severe storms more likely to happen?
During low pressure systems
What is a meteorologist?
People who use data to predict weather
Do land and water heat equally?
NO, land heats faster than water and cools faster than water
What happens when relative humidity is 100%?
Which types of air masses are polar?
cold air masses
What does a blue H represent on a weather map?
A high pressure system.
What is a weather model?
computer simulation using data to help predict future weather
How can a mountain cause changes in weather?
What is humidity?
The amount of water vapor in the air
What happens when air masses interact?
What does a red L represent on a weather map?
Low pressure system
air rises, this is where clouds, condensation and precipitation can happen
How can the shorelines cause changes in weather?
