It's a Mass
A huge body of air that has similar temperature, humidity, and air pressure at any given height.
What is an air mass?
This measures the speed of wind.
What is anemometer?
Isobars on a weather map show this
What is air pressure
Warm air rises and puts little pressure on the earth's surface.
What is a low pressure area?
The weather forecast indicates that the weather will be turning cold very quickly with the chance of a tornado. What type of front would cause this?
What is a cold front.
Weather is caused by the movement of water in the atmosphere. That movement is influenced by these four things.
What are winds, landforms, ocean temperature, and ocean current.
A pair of air masses, neither of which is strong enough to replace the other.
What is stationary front?
To measure the temperature of the air, use this.
What is a thermometer
Isotherms on a weather map show this
What is temperature?
The push of air against its surroundings.
What is air pressure?
This type of front is when a warm and cold front meet. It brings many days of cloudy, wet weather.
What is a stationary front.
Ocean and atmospheric currents are affected by these three things.
Latitude, altitude, and geography.
What is it called where two air masses meet?
What is a front?
Use this to measure air pressure
What is a barometer?
The symbol for a cold front is a curved line with these shapes on it.
What is are triangles?
Differences in air pressure would cause what?
What is wind.
The weather forecast indicates that the weather will be turning cold very quickly with the chance of a tornado. What type of front would cause this?
What is a cold front.
The ocean absorbs this and redistributes it using its currents.
Sun's energy
This type of front is when a warm and cold front are moving in the same direction.
What is an occluded front.
Use this tool to measure the humidity in the air.
What is a hygrometer?
A curved line with semi-circles on it is the symbol this type of weather.
What is a warm front?
Cold air sinks and presses on the ground.
What is a high pressure area?
The type of weather you can expect with a high pressure area.
What is fairly stable and usually fair weather?
In order to prove something, scientists have to gather this.
Evidence
Both the ocean and the air have these, which effect the weather.
What are currents?
This instrument is used to determine the amount of rain that fell in a certain period of time
What is a rain gauge?
A bold capitol letter (H or L) on weather map indicate large areas of this.
High or Low pressure
This is Atmospheric Pressure
The amount of pressure (or weight) of the air around you
Expect this type of weather can you expect with low pressure
What are cloudy days with precipitation?
