Event Rules
What are the rules about binders?
You can have as much as you want inside, and are expected to carry a U.S map with state names.
Precipitation
any liquid or solid water particle—such as rain, snow, sleet, or hail—that falls from atmospheric clouds to the Earth's surface due to gravity
What is the difference between climate and weather?
Climate is long term while weather is short term.
Would you use an anemometer or a wind vane when you are trying to find wind speed?
Anomometer
At least 50% of questions based on:
Interpretations of weather data displayed in maps, graphs, images, photographs, charts, and/or tables to analyze data.
Atmosphere and levels (EThMeSTro)
The atmosphere is the protective, gaseous envelope (air) surrounding the Earth, held in place by gravity.
Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere (we live here).
What are the main components of weather?
Temperature, pressure, wind, humidity, precipitation, and cloud cover.
What does the 20% chance of rain actually mean?
It means a 20% probability that any given point in the forecast area will recieve measurable rain (atleast 0.001 inches).
Calculator rules?
Each team may bring up to two Class II calculators.
Cloud types
High-level (above 20,000 ft), Ci Cc Cs (CIRRUS)
Mid-level (6,500 to 20,000 ft), Ac As Ns (ALTO) (STRATUS)
Low-level (below 6,500 ft), St Cu Sc Cb (STRATUS) (NIMBUS)
What causes the seasons?
The Earth's tilt.
Can lightning strike the same place twice? If yes, why?
Yes, an example of this is the NYC Empire State Building, which is struck over 25 times a year. Lightning is attracted to the highest and sharpest areas. This is why some places are struck by lightning multiple times.
If the event features rotation through a series of stations
No material may be removed from the binder during the event.
Air mass
A huge body of air (hundreds or thousands of miles wide) with, generally, the same temperature and moisture content throughout.
What does a barometer measure?
Atmospheric pressure.
How many days does it take before a forecast is no longer accurate?
A forecast stops being accurate after 10 days.
Cloud prefixes
Cirro - high level
Alto - mid level
Nimbo - rain-producing clouds
Cumulo - puffy, vertically growing
Strato/Stratus - layered or sheet-like
Which layer holds most of the atmosphere's moisture?
The troposphere.
