Weather or Not
Description:
This competition will test the student's knowledge of
meteorological terms, techniques, and events.
Number of Participants: 2
Approximate Time: 45 minutes
The Competition:
1. Student teams will be quizzed in the form of a test on
basic weather terms, concepts, and techniques. Material
may include clouds, instruments, weather patterns, severe
weather, and major weather events.
2. The test may include maps (meteorological and
climatologically), charts (clouds), graphs (climatic zones),
drawings (station models, sea/land breeze, fronts), diagrams
(isobars, isotherms, lightning), and photographs in addition
to basic questions.
3. Stations may be set up enabling students to make
readings on a variety of simple scientific weather instruments
such as thermometers, barometers, and anemometers.
4. Students will have 45 minutes to complete the test. Time
is not a scoring factor.
Scoring: The winner will be the one who achieved the
highest score. Ties will be broken with supplemental
questions that will only be scored in the event of a tie.

How are orographic clouds formed?
Orographic clouds are formed by air being lifted due to topography. This air rises to its
dew point, condenses, and creates orographic clouds
Why are there generally clouds in a low pressure center?
Air in a low pressure converges and is forced to rise. This air rises to its dew
point, condenses, and creates clouds

Hemisphere and deflects objects to the (left, right) in the Southern
Hemisphere.
Right; left
Where on earth is the Corollas Force the greatest?
Near the poles; there is no Corollas force at the equator
What are the four types of fronts?
Occluded, Stationary, Warm, Cold
In the southern hemisphere, winds flow (clockwise, counterclockwise)
around a high pressure center and flow (clockwise, counterclockwise)
around a low pressure system.
Counterclockwise; clockwise
What is a dry line?
A dry line is a moisture boundary that separates a moist air mass from a dry
air mass
What is an isobar?
An isobar is a line drawn on a weather map connecting points of equal
pressure
What does the Beaufort Scale measure?
The Beaufort scale measures wind strength
_
How are rainbows created? Where must you be standing to see one?
A rainbow is an arc of concentric colored bands formed by refraction
(bending of light) and internal reflection of sunlight by falling raindrops. An
observer must be looking at a shaft of falling rain with the sun at his/her
back
What is a Chinook wind?
A Chinook wind consists of air that is adiabatically compressed as it is
drawn down the leeward slope of a mountain. As a consequence, the air is
warm and dry.
Why are cloudy nights generally warmer than cloudless nights?
Radiation leaves the earth and doesn’t encounter any obstacles. Without the
insulation that clouds provide, the night becomes chilly
