Variables and Instruments
Instrument for indicating wind direction.
What is a wind vane?
This phase change results as water releases 334j/g of energy.
What is freezing?
Season in NYS when Earth is farthest from the Sun.
What is summer?
Source region of cP air mass that affects NY.
What is Canada?
These storms are the planet's largest.
What are hurricanes or typhoons?
This instrument measures average kinetic energy of matter.
What is a thermometer?
This water property is the reason that ocean shoreline areas are more moderate in temperature than inland.
What is the high specific heat of liquid water?
Latitude at which the noon Sun is highest on September 21
What is the Equator?
The symbol and properties of a land based air mass with a source region of low latitude.
What cT, dry and warm?
The storms that can be the cause of tornadoes.
What are Mesocyclones or Supercell thunderstorms?
This instrument measures air pressure.
What is a barometer?
This temperature change in rising air is the result of decreasing pressure with no heat exchange.
What is Adiabatic cooling?
Month when the noon Sun is 90 degrees to the surface at the Tropic of Cancer.
What is June?
The least dense of the air masses.
What is mT?
These microclimates form on the leeward side of Mountain Ranges due to adiabatic warming of air.
What are rain shadow deserts?
This weather variable is measured using an Anemometer.
What is wind speed?
The Relative Humidity on a 11C day when the Dew Point is 7C
What is 77% ?
Your latitude if your noon sun is 40 degrees above the North horizon on March 20
What is 50S?
Imaginary seasonal boundary between cP and mT air in the U.S.
What is the Stationary Polar Front?
A weather Station Model shows pressure data that reads 705, so this is the actual barometric pressure in mb
What is 970.5 mb?
A psychrometer is used to determine both Dew Point and Relative Humidity. It directly measures the effect of this water cycle process on the wet bulb of the instrument.
What is evaporation?
This process causes a dramatic drop in air's Adiabatic Lapse Rate.
What is condensation, deposition or glaciation?
Difference in angle of the noon sun between June 20 and December 20 here in NY
What is 47 degrees ?
These low pressure frontal systems bring the Eastern U.S. much of its weather.
What are Mid Latitude Cyclones?
Air movement pattern around an anti-cyclone in the southern hemispere. (three descriptors, vertical motion, toward or away from center, and rotation)
What is downward, outward from the center, and counter clockwise (or left)?
