ATMS 103 Exam 3 Guide With
Complete Solution
In the scales of atmospheric motion, _____________ motions occur on a scale
larger than mesoscale motions.
synoptic
A ____________ breeze {choose one; "sea" or "land"} is most likely observed at
the beach during daylight hours.
sea
The single-cell model of global winds, also known as the __________ cell, shows
rising motions in the tropics and sinking motion at the poles.
Hadley
The warm ocean current known as the ________ is located just off the coast of
North Carolina.
gulf stream
People who enjoy experiencing snowstorms along the eastern United States
hope for a _________ phase {choose on; "positive" or "negative"} of the North
Atlantic Oscillation, which tends to improve the chances of cold air diving
farther south in the region.
negative
Micro-scale
, smallest scale of motion (2m)
Example of Micro-scale
tiny eddies within smoke
Mesoscale
middle scale; circulation of city air (ranges but can be a few km to 100km)
Example of Mesoscale
thunderstorms
Synoptic Scale
typical weather map scale that shows features such as high and low pressure
areas (2,000 km)
Example of Synoptic Scale
cyclones
Macro-scale
largest size and longest life span of the different classes. (1,000 km) (spans
several days or weeks)
Example of Macro-scale
El Nino
Planetary Scale
the largest scale of motion, sometimes called the global scale. long waves in
the atmosphere (5,000 km)
Example of Planetary Scale
