Weather Quiz 1 Flashcards
Celsius to Fahrenheit conversion
9/5 * C + 32
Fahrenheit to celsius conversion
5/9 * (F-32)
most important components of the atmosphere to aviation
Water vapor, ozone, oxygen, nitrogen
Primary unity of the meteorological community
Milibars
In what way is MSL rather than station pressure more appropriate
MSL accounts for different elevations at which the surface is measured at various locations
Layers of atmosphere in order
troposphere (colder)
stratosphere (warmer)
mesosphere (colder)
thermosphere (warmer)
What comes with temperature inversions
fog/smog
windy below, calm above
freezing rain
Line of constant temperature
isotherm
50F = ?C
10C
Where is surface temperature taken?
1.5 M above the ground and in the shade, typically on a grass surface
what is a temperature gradient
change in temperature over a specific distance
What is the altitude range of the troposphere?
surface - 36,000 ft
what is the pressure range in the troposphere
1000 mb to 250mb
What are the methods for transferring energy
conduction
convection
advection
latent heating
radiative heat transfer
What is conduction
transfer of energy between things in contact with each other
what is convection
transfer of energy upward as air rises
what is advection
horizontal transfer of energy (warm air replacing cold air with wind)
what is latent heating
energy absorbed / released when water changes phases
what is radiative heat transfer
energy from the sun (or fire) absorbed by things in it’s path
Rising air always ____ and ____
expands, cools
(kinetic energy decreases)
vapor pressure
force per area applied by only the water vapor molecules
mixing ratio
ratio of the amount of water contained in a given amount of air
dew point
temperature to which air would need to be cooled to become saturated
clouds, fog, dew forms if temperature reaches this point
dew point depression
numerical difference between temperature and dew point
