Weather terms

What is the most dense type of Air Mass
Continental Polar - Cp
100
This is a fast moving ribbon of air in the upper atmosphere
Jet stream
100
They are produced rapidly when rising air causes cumulus clouds to build upward and are characterized by the presence of lightning
A thunderstorm
100
The change of state of liquid water to gas
Evaporation
100
The combination of particulate matter and/or some gases mixing with water vapor forms
Acid rain
200
This is the leading edge of an air mass that brings a temperature increase and steady rain
Warm front
200
All winds result from uneven heating of the atmosphere making this is very important in moving heat through the atmosphere
Convection
200
These are high level clouds and due to high altitude, the water is frozen to form ice crystals
Cirrus clouds
200
The change of state of gaseous water vapor to liquid water
Condensation
200
A colloid of smoke, fog, and chemicals
Smog
300
This is the least common type of air mass, it forms typically over deserts
Continental tropical - Ct
300
Name the 4 most abundant gasses in the atmosphere
Nitrogen (78%), Oxygen (21%), Argon (0.93%), Carbon dioxide (0.04%)
300
This is a type of cloud that brings precipitation, it is always added to another cloud form
Nimbus or Nimbo
300
This is any form of water falling from the sky and reaching the ground
Precipitation
300
This refers to the weight of the Earth’s atmosphere pressing down on everything at the surface
Air pressure
400
When two air masses meet but that are far from their source area this will form
Stationary front
400
This is what causes winds and currents tend to flow to the right north of the equator
The Coriolis effect
400
These are huge, rotating storms that form over the ocean near the equator. They produce very strong winds, heavy rains, and large, powerful waves and can cause severe flooding and damage from strong winds.
A hurricane
400
This is when any form of water remains in one place for an extended period of time
Deposition
400
compares the actual amount of water vapor in the air with the maximum amount of water vapor the air can hold at that temperature
Relative humidity
500
This is an occurrence where three Air masses meet and interact
Occluded front
500
Name the five layer of the atmosphere a rocket would travel on its way to the moon.
Troposphere - Stratosphere - Mesosphere - Thermosphere - Exosphere
500
This is the most common cloud type - it has several forms and is associated with thunderstorms
Cumulonimbus - Cb
500
This occurs when solid water changes state to gaseous form with out going through the liquid state
Sublimation
500
A powerful, warm surface current in the North Atlantic Ocean. It is one of the strongest know currents starting from the equator
The Gulf Stream
