clouds
Describe a Cirrus cloud
short, detached, hair-like clouds found at high altitudes
forms when a cold, dense air mass pushes under a warm, lighter air mass, forcing the warm air to rise
What is a cold front
What is Doppler radar
obtains weather information (precipitation and wind) based upon returned energy
how are tornadoes formed
when wind variations with height support rotation in the updraft
Describe a Altocumulus cloud
small mid-level layers or patches of clouds, called cloudlets, which most commonly exist in the shape of rounded clumps
forms when a relatively moist, warm air mass slides up and over a cold air mass
What is a warm front
what is a EF Scale
used to assign a tornado a 'rating' based on estimated wind speeds
how are heat waves formed
when high pressure in the atmosphere moves in and pushes warm air toward the ground
Describe a Cumulus cloud
detached, individual, cauliflower-shaped clouds usually spotted in fair weather conditions
forms when a cold front or warm front stops moving
what is a stationary front
what is a satellite data
satellite imagery and earth observation data of the earth's surface and its atmosphere.
how are earthquakes formed
sudden movement along faults within the Earth
Describe a Shelf cloud
An arcus cloud is a low, horizontal cloud formation, usually appearing as an accessory cloud to a cumulonimbus
a composite of two fronts, formed as a cold front overtakes a warm
what is a occluded front
what is a Radiosondes
small instrument package that is suspended below balloon filled with either hydrogen
how are hurricanes formed
Hurricanes form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity
Describe a Cirrostratus cloud
An arcus cloud is a low, horizontal cloud formation, usually appearing as an accessory cloud to a cumulonimbus
the weather front boundary between the polar cell and the Ferrel cell around the 60° latitude, near the polar regions, in both hemispheres
What is a polar front
Automated surface-observing systems
automatically provides computer-generated voice observations to aircraft in the vicinity using FAA ground-to-air radio frequencies
how are floods formed
when prolonged rain falls over several days, when intense rain falls over a short period of time, or when an ice or debris jam causes a river or stream to overflow onto the surrounding area.
