The merging of liquid cloud dropplets by collision is called.
10 inches of snow = 1 inch of liquid water.
if a city were to receive 1/2 inch of rain in the morining and one inch of rain in the afternoon, about how much precipitation would the weather service report for that day.
1 inch .
Large clould droplets fall faster than smaller cloud droplets because:
The ratio of the drop's surface area to its weight is smaller.
Who invented the mercury barometer?
The ______ is an apparent force created by the earth's rotation.
The howling of wind on a blustery night is believed to be caused by:
eddies of higher air density.
A wind Rose Indicates
The percentage of time that the wind blows from different directions.
The heat form a chinook wind is generated mainly by:
only ice crystals
exist in a cloud, the cloud is said to be:
What are the two main substances used in cloud seeding?
Silver Iodide, and dry ice
Fall streaks usually____ before reachin the ground
A Coriolis force is the result of :
Ice Nuclei may be:
a) Ice crystals
b) certain clay minerals
c) bacteria in decaying plan leaf material.
d) all of these
D All of these!!!
Rain that falls from a cloud but evaporates before reaching the ground is refered to as:
A true blizzard is characterized by:
a) low temperatures
b) strong winds
c) reduced visibility
d) blowing snow
e) all of the above
All of the above!!!!
On average, the water equivalent of 10 inches of snow is about ___ inches of water.
The lightest form of rain is:
Which of the following would produce the strongest coriolis force?
Fast wind and high latitude would produce the strongest coriolis force.
The wind arround a surface low pressure center in the Sountehrn Hemisphere blows:
d) Clockwise and inward toward the center
Look at the low pressure high pressure system drawings
The friction of fluid flow is called:
An abrupt change in wind speed and wind Direction is called:
An of shoere wind
Blows from land
An instrument used to measure wind speed is called an:
which of the instruments below indicate both wind speed and wind direction?
Friction slows down winds near the Earth's surface.
On a weather map, closely spaced isobars or contour lines indicate a region of high winds becase in this region there is a strong pressure gradient.
The coriolis force directs winds to the right of their path in the southern hemisphere
In general, the closer the isobars, the weaker the winds.
Shelter belts are used to protect crops form strong prevailing winds
Usually the windward side of a mountain rainge will have fewer clouds over it than will hte leeward side.
Rain amount sof less than .01" is consider a trace.
The Coriolis force is zero at the equator.
When the wind flows in large, looping meanders, following a more north south trajectory paralleling the flow is termal zone
During an easterly wind, a wind vane will mpoint toward the west.
The smallest scale of atmospheric motion is the:
