Review Flashcards
2 types of temperature inversion
Radiation (or nocturnal) inversion—happening on a cool, clear night.
Frontal inversion –where cold air lifts warmer air aloft.
Prevents nocturnal temperature inversions
Overcast skies (the greenhouse effect)
What layer of the atmosphere does weather occur?
Troposphere
Standard pressure
- 92 hg
1013. 2 mb/hp
Isobars
lines connecting points of equal pressure corrected to sea level, usually spaced 4 mb apart
Coriolis Force acts
force acts perpendicular to the right of the wind, (or any non-steered objects in the Northern Hemisphere).
Surface friction causes
Wind speed to decrease and pushes wind across isobars
Buys Ballot’s Law
standing with your back to the wind, in the northern hemisphere, the low will be to your left.
Condensation may occur when
the spread is 2°C (4°F) or less.
process when solid changes directly to a gas
Sublimation
process when vapor changes directly to solid.
Deposition
Dry cooling rate
3 degrees
Moist cooling rate
1.5 degrees
The primary cause of frontal weather
the lifting of warm moist air by colder, more dense air.
Type of fog from adiabatic cooling
Upslope fog
