Meteorology Study Guide Flashcards
Do land breezes happen in Day Time or Night Time?
Night time
What is wind speed calculated by?
An anemometer
What phases of matter are involved in the water cycle?
Gasses, liquids, and solids
Evaporation needs___ to happen.
Heat
Condensation needs to _____ energy to turn gasses into liquids.
Lose
What is dew point?
Dew Point the is the temperature air must cool to for the air to be saturated.
Warm air holds ____ water vapor than cold air.
More
How do I know how humid it will be?
The farther apart air temperature and dew point temperature, the less humidity.
Ingredients to a cloud?
Water vapor, condensation nuclei, and temperature decrease
What kind of clouds are there?
Cumulus( puffy), cirrus(wispy), stratus(layered)
What do you use to measure humidity?
A sling psychrometer
What is relative humidity?
Relative humidity compares the amount of water vapor in the air to how much it can hold in that temperature
What is infiltration?
When water soaks into the ground
What is percolation?
The moving water that is under ground
How do air masses get its temperature and humidity?
Air masses get its temperature and humidity from the land or water it came from.
Where does most of our weather come from?
Most weather comes from air masses.
How is wind created?
It is created from air pressure differences, and those differences are created by the unequal heating of the earth.
Why is the earth unevenly heated?
It is spherical, has seasons, differences in materials on earth, and different climate zones.
Does wind move in a circle?
Wind isn’t moving in one big circle. The hot air rises at the equator and starts to cool. The cool air sinks at 30 degrees North and South. That causes a high pressure area near 30 degrees north and south. The sinking air at the pools gets warmer before getting to the equator and drops
Why is the movement of wind curved?
Because of the earth’s rotation.
What are global and local winds caused by?
They are caused by unequal heating and pressure differences.
Where and how do local winds move?
Local winds move short distances and can blow from any direction.
What are global winds apart of?
Global winds are part of a circular air pattern that moves across the earth.
Why do trade winds curve?
They curve because of the Coriolis effect
