A boundary between two masses
Front
This tool measures how hot or cold it is outside.
temperature
Because the eather is tilted on is Axis, the planets surface is heated in different ways and for different periods of time. Which part of the earth gets the most consistent sunlight?
The equator.
What are the three different kinds of wind currents?
Polar Easterlies, Westerlies, Trade Winds
Warm air catches up with cold air mass moving in the same direction. This will bring a lot of rain, followed by cloudy days.
Warm Front
snowstorm with low visibility and high winds
Blizzard
hygrometer
Which parts of the earth get the most inconsistent heat from the sun?
The North and South Poles
What direction do Jet Streams flow?
West to East
Cold air runs into warm air- the cold air sinks because it is denser, which pushes the warm up- causing it to eventually cool down. This often causes snow or big clouds because the warm air will slowly raise up over the cold air. This will eventually cause fair weather.
Cold Front
what is 3 examples of presipitation
rain, snow, hail, and sleet
Satellite and Radar
What is this cycle called?
The Water Cycle
Wind flows from areas of ____ air pressure, to areas of ___ air pressure
HIGH to LOW
When a warm air mass is between two cold air masses.
Occluded Front
Fast moving currents of air that blow from WEST to EAST around the earth, high above the earth’s surface.
Jet Streams
1) Anometer
2) Weather Vane
Convection currents are created by the uneven heating of the Earth. Cool air falls and warm air rises.
What are these winds called?
Scientists use air pressure to predict.....
wind speeds.
When a cold air mass and a warm air mass meet and both STOP moving forward. Clouds and light rain occur at the front and the weather takes a long time to change.
Stationary Front
The state of the lower atmosphere in a specific place and at a specific time, including temperature, precipitation, wind, humidity, air pressure, and cloudiness.
Weather
barometer
Ocean currents are also created by the uneven heating of the Earth. Warm and cold water currents move thanks to the transfer of thermal energy.
What kind of current hits our coastline here in Oregon?
Cool Ocean Current
True or False:
Humidity is the measure of rain falling from the sky
FALSE
In a high pressure system the air is
_______ .
sinking down to the ground
