Air Pressure
Air moves from ________to __________pressure
High to low
This is the temperature at which air with a given amount of water vapor will reach saturation.
What is "the dew point"
This is what causes winds to move
What is uneven heating of Earth's surface
"Cloud condensation nuclei", these nuclei are hygroscopic meaning....
They are water (vapor) loving
A line of equal pressure on a map
What is an isobar?
Air pressure does this as you move higher in the atmosphere
What is decreases
In terms of pressure systems, this is how wind moves
What is from high pressure towards lower pressure
The total number of molecules escaping from the liquid (evaporating) is balanced by the number returning (condensing)
The rate at which the air temp changes with altitude
What is the environmental lapse rate?
These types of clouds are puffy white clouds that look like cotton balls. They usually appear in fair weather.
What are cumulus clouds
Winds that are over 75 mph
What are hurricane force winds?
Molecules evaporate more rapidly from highly curved surfaces, such as a small water droplet (so smaller water droplets require higher vapor pressure or supersaturation to reach equilibrium)
What is the curvature effect?
When air is compressed, its molecules are forced into a smaller space, which increases their kinetic energy.
What is adiabatic heating?
These types of clouds form in layers low in the sky and produce steady, light precipitation
What are stratus clouds
These winds in California are most common from fall to spring and move from Northeast to Southwest.
What are the Santa Ana winds
This type of precipitation is rain that freezes into ice pellets while falling through cold air
What is sleet
Air that moves farther away from its original position
What is unstable equilibrium?
Clouds that form just downwind from a mountain peak.
What is a banner cloud?
Wind that moves from east to the west
What is an easterly wind?
This precipitation is rain that instantly freezes upon contact with surfaces, creating an icy glaze.
What is drizzle
The dry adiabatic rate
10oC for every 1000m change
