Fog
The most common and natural fog that forms overnight as the ground loses heat into the cool night air:
Radiation Fog
This precipitation is smaller than a raindrop:
Drizzle
Ice crystals usually in geometric shapes:
Snow
A lack of precipitation that affects an area's crops:
Agricultural Drought
This air mass is cold and dry.
Continental Polar
A brownish haze that forms as complex molecules are broken down into the ozone as harmful substances:
Photochemical Smog
The most common form of precipitation:
Rain
A supercooled cloud droplet that is swept up multiple times into the coldest part of a cloud, creating layers of ice called a rime and glaze:
Hail
When an area is receiving less precipitation than normal:
Meteorological Drought
This air mass forms over the Caribbean Sea.
Maritime Tropical
This fog forms when wind heated by warm ocean water blows over cool ocean water:
Sea Fog
The movement of water from the earth's surface, into the air, and back to the surface again:
Hydrologic Cycle (Water Cycle)
Hail forms due to continuos updrafts during strong _______________________.
Thunderstorms
This front forms when a cold front overtakes a warm front:
Occluded Front
This is a front of two unmoving air masses of different temperatures, and from which a frontal cyclone can begin.
Stationary Front
This fog can form day or night and moves wherever the wind does:
Advection Fog
Liquid precipitation that freezes once it hits a surface:
Freezing Rain
A brief but intense snow fall:
Snow Squall
This front forms when a maritime polar air mass pushes into a continental tropical air mass:
Cold Front
The area of the surface over which an air mass formed is called the air mass's:
Source Region
When fog develops in air below freezing, forming layers of ice on the ground beneath the fog:
Freezing Fog
In order for clouds to form, water vapor needs _____________________________ to form around.
Condensation Nuclei
An extended period of heavy snow and high winds:
Blizzard
These TWO types of air masses forms over oceans:
Maritime Tropical Air Mass
Maritime Polar Air Mass
The boundary between two air masses of different temperatures:
