 Air
mass has a large region of air that has a
similar temperature and humidity. Air masses
can cover thousands of land and water.
A
barometer is a instrument that measures
air pressure. People can use a barometer to
measure the air pressure before there is a
storm.
A
cyclone is any kind of storm with a low
pressure center and a counter-clockwise
rotation. Hurricanes and tornados are
considered a cyclone.
A
drought is a long period of dry weather. In
a drought crops can be destroyed and water
can be lost.
A
Earthquake is when planks underground
move it causes motion. If earthquakes are
powerful enough they can cause major
destruction to your city.
Fog is a cloud that forms near the ground.
While your driving you have to be extra careful
because if your not you could cause a car
crash.
 Glaze
is a smooth clear icy coating of
supercooled water droplet that spreads out
and freezes onto objects on contact. Glaze
produces the accretion of a ice storm.
 The
name for a tropical cyclone with
sustained winds that go up to 74 miles per
hour or greater in the North Atlantic Ocean,
Caribbean Sea, Gulf of Mexico, and in the
North Pacific Ocean. Hurricanes can destroy
people’s houses.
Ice is a solid form of water. Ice cubes go inside
your cup of water.
Jet Streams are powerful winds that flow at a
high altitude. A lot stretch for thousands of
miles.
 Katabatic
winds are created by air flowing
down hill. When the air is warm it might be
called a foelin wind it also may be known as
a Santa Ana.
A
lake effect snow is a snow showers they
are created when cold dry air passes over a
large warmer lake like one of the Great
Lakes. It picks up moisture in the air .
 Maximum
is the greatest value attained by a
function for example, temperature, pressure, or
wind speed. Maximum is the opposite of minimum.
A
neap tide is a tide of decreased range, it
occurs about every two weeks when the
moon is at one quarter or three quarters full.
 Overcast
is the amount of the sky cover for a
cloud layer that is 8/8ths on the summation
layer for that layer.
 Precipitation
is any and all forms of water.
Water can be rain, ice, hail, and etc. when
there is a storm I see rain falling from the
clouds.
A
forecast of rain fall, snowfall, or liquid
equivalent of snow fall. Whenever people
watch the news on the weather the person
gives you a forecast.
A rain shadow is also referred to as a
precipitation shadow. It is on the lee side of
the mountain or a similar barrier where the
rain is less than on the other side.
A sandstorm is a strong wind carrying sand
particles through the air. There are low
occurrences. Some sandstorms are usually only
ten feet, no more than fifty feet.
A
violently rotating column of air in contact
with and extending between a convective
cloud and the surface of the Earth. In the
Wizard of Oz a tornado destroyed Dorothy's
house.
 The
direction from where the wind is
blowing. If a up wind blows a certain
direction it could make a tree fall on your
house. A up wind can make very cold air.
A
vortex is any circular or rotary flow in the
atmosphere that possesses vortices.
Sometimes a vortex can look like a tornado
because it is circular.
 The
state of the atmosphere at a specific
time and with respect to its effect. There
are different types of weather.
X-rays are the portion of a electromagnet that
has a very shot wave length. It has a wave
length longer than gamma rays that are shorter
than a visible light.
Yellow snow is snow that is given a golden or
yellow glow by appearance or by the presence
of pine or cypress pollen in it. Sometimes
people put a yellow light on snow to make it
look like yellow snow.
 Zenith
is the point which is elevated at 90
degrees from all points on given observers
astronomical horizon. The point on any given
observers celestial sphere that lies directly
above them.
