Fog / Precipitation
Air Masses
100
This is the cause of wind in the atmosphere
What is change in air pressure or temperature, the rising and sinking of air
100
This is the cycle in which water evaporates, condenses, precipiates, and repeats the process.
What is the Water Cycle
100
This low level cloud type consists of fluffy "cotton ball-like" clouds about the size of your fist
What is cumulus
100
This form of precipitation falls to the ground as liquid water
What is rain
100
These are air masses which form closer to the equator in warmer regions.
What are tropical air masses
200
This is the Effect in which winds are deflected to right in the Northern Hempishere due to the rotation of the Earth
What is the Coriolis Effect
200
This is the term for the amount of water vapor in the air at a given time.
What is humidity
200
This low level cloud type is a thick layer of clouds that stretches across the sky
What is stratus
200
This type of precipitation consists of a collection of small ice crystals and falls gently to the ground during winter months.
What is snow
200
This term is used to describe any air masses which form over the ocean.
What is maritime
300
This is a circular flow of air that rises in one area, moves across the atmosphere and sinks back down in another area (Ex: 30-60 degress N)
What is a convection cell
300
When water evaporates it takes with it some energy from the remaining water in the form of this type of heat.
What is latent heat
300
This high-level cloud type is thin and "feathery"
What is cirrus
300
This type of fog forms when a warm surface comes in contact with cooler air above.
What is radiation fog
300
Air within an air mass must have these two similarities throughout the mass
What is temperature and humidity
400
These are local winds found at coastlines which alternate from sea to land and land to sea each day.
What are sea breezes and land breezes
400
This is a device using dry bulb and wet bulb thermometers to determine the relative humidity
What is a psychrometer
400
These are particles in the atmosphere which water condenses upon to make clouds
What is condensation nuclei
400
This type of precipitation accumulates many layers of ice as it is carried back into clouds by updrafts before falling to the ground
What is hail
400
These are the four main types of air masses
What are maritime polar (mP), maritime tropical (mT), conitnental polar (cP), and continental tropical (cT)
500
These are the six global wind cells from the North Pole to the South Pole.
What are Polar Easterlies, Westerlies, NE Trade Winds, SE Trade Winds, Westerlies, and Polar Easterlies
500
This is the term used for air that holds the maximum water vapor possible.
What is saturated
500
This low level cloud type can be thousands of meters in height and can produce thunderstorms and hail.
What is cumulonimbus
500
This type of fog forms when a warm air flows over a cold surface
What is advection fog
500
These are the six specific air masses which effect the United States (use specific source regions)
What is Martime Poiar - Pacific, Maritime Polar - Atlantic, Continental Polar - Canada, Maritime Tropical - Pacific, Maritime Tropical - Atlantic, and Continental Tropic - Mexico
