METEOROLOGY FINAL EXAM STUDY
GUIDE
Which cloud would most likely produce drizzle? - Correct Answers -stratus
If rain falls on one side of the street and not on the other side, the rain most likely fell
from a what type of cloud. - Correct Answers -cumulonimbus
The part of the cloud where only ice particles exist is called - Correct Answers -glaciated
The growth of a precipitation particle by the collision of an ice crystal (or snowflake) with
a supercooled liquid droplet is called: - Correct Answers -accretion
Rain which falls from a cloud but evaporates before reaching the ground is referred to
as - Correct Answers -virga
The most common ice crystal shape: - Correct Answers -dendrite
In the winter you read online that a large section of the Midwest is without power due to
downed power lines. Which form of precipitation would most likely cause this situation?
- Correct Answers -freezing rain
Which is the correct association? - Correct Answers -snow squall-- intense snow
shower
Which of the following might be mistaken for hail? - Correct Answers -graupel
Precipitation with the greatest size (diameter) is: - Correct Answers -a hailstone
On average, the water equivalent of 10 inches of snow is about how many inches of
water - Correct Answers -1
An important factor in the production of rain by the collision-coalescence process is the
number of ice crystals in the cloud - Correct Answers -False
After a rainstorm, visibility typically deteriorates - Correct Answers -False
Bacteria in a decaying plant leaf material can act as ice nuclei - Correct Answers -True
,Large, heavy snowflakes are associated with moist air and temperatures well below
freezing - Correct Answers -False
Large cloud droplets fall faster than small cloud droplets because gravity acts more
strongly on larger objects - Correct Answers -False
Very small cloud droplets of water can evaporate even when the relative humidity is 100
percent. - Correct Answers -True
Generally, the concentration of nuclei is less over the oceans than it is over land. -
Correct Answers -True
In dry powdery snow, the water equivalent ratio may be as high as - Correct Answers -
30:1
Raindrops that reach Earth's surface are seldom larger than - Correct Answers -5mm
Chicago, Illinois (latitude 42°N) is located in the - Correct Answers -westerlies
In Honolulu, Hawaii (latitude 21 degrees North) you would most likely experience winds
blowing from the - Correct Answers -northeast
At Barrow, Alaska (latitude 70 degrees North), you would expect the prevailing wind to
be - Correct Answers -easterly
According to the three-cell general circulation model, at the equator we would not
expect to find: - Correct Answers -a ridge of high pressure
The majority of the United States lies within this wind belt - Correct Answers -westerlies
The world's deserts are found at 30° latitude because: - Correct Answers -of the sinking
air of the subtropical highs
Which statement describes the subtropical jet stream? - Correct Answers -It generally
blows from west to east
Which statement describes the polar front jet stream? - Correct Answers -It forms near
the boundary called the polar front.
In the Northern Hemisphere, the polar front jet stream is strongest when - Correct
Answers -air north of the polar front is much colder than air south of the polar front
The jet stream flows - Correct Answers -in a wavy pattern from west to east
The low level jet that forms over the central plains of the United States in the summer
appears to be responsible for - Correct Answers -nighttime thunderstorms
, The cold water observed along the Northern California coast in summer is due mainly to
- Correct Answers -upwelling
The name given to the current of warm water that replaces cold surface along the coast
of Peru and Ecuador during December is - Correct Answers -El Nino
Upwelling is - Correct Answers -the rising of cold water from below
During a major El Niño event - Correct Answers -extensive ocean warming occurs over
the tropical Pacific
A condition where the central and eastern tropical Pacific Ocean turns cooler than
normal is called: - Correct Answers -La Nina
The reversals of the positions of surface high and low pressure at opposite ends of the
Pacific Ocean is called: - Correct Answers -The Southern Oscillation
The ultimate cause of jet streams is: - Correct Answers -the energy imbalance between
high and low latitudes.
For upwelling to occur on the east coast of the U.S., winds flowing from which direction
have to exist - Correct Answers -south
During the negative cold phase of the Arctic Oscillation, when Greenland is
experiencing mild winters, northern Europe usually experiences which type of winters -
Correct Answers -cold
The origin of cP and cA air masses that enter the United States is - Correct Answers -
Northern Canada and Alaska
Compared to an mP air mass, mT air is - Correct Answers -warmer and moister
The greatest contrast in both temperature and moisture will occur along the boundary
separating which air masses? - Correct Answers -mT and cP
One would expect a cP air mass to be: - Correct Answers -cold and dry
The coldest of all air masses is ____. - Correct Answers -cA
Record breaking low temperatures are associated with which air mass? - Correct
Answers -cP
The designation for a cool, moist air mass is - Correct Answers -mP
