Ch 4 & 5 Flashcards
Heat stored in the air w/water vapor.
Latent heat
A change in pressure & temperature of air rising or descending.
Adiabatic cooling and warming
Laten heat is Non sensible, cannot be felt. Also called
Hidden energy
Becomes heat of condensation when water vapor condenses and becomes liquid water droplets
Later heat
Lower angles of incidence have less
Energy
Clouds and haze deplete insolation
Atmosphere obstruction
What is always colder and hotter than water
Land (5x faster)
Higher and lower temps in what hemispheres why
Higher in north than south surrounded by wayer
Prominent controls of temperature
Altitude
Latitude
Land/water contrasts
Ocean currents
How does adiabatic cooling happen
Expansion=less collision=molecules spread(using energy)=lower temp.
Adiabatic warming
Compression=closer molecules=more collision= higher temp.
The force a gas exerts on some specified area of the container wall
Pressure
The force exerted by gas molecules in the atmosphere on earths surface it a body
Atmosphere pressure
Impact of pressure in landscape
Indirect impact
Affects temp.
Affects wind
Impact if wind
Obvious effects
Factors influencing atmosphere pressure
Temperature
Density
Temperature increase in speed
Greater force in collision an greater pressure
Temperature as a pressure influencer
Pressure of gas proportional to “”
Density “mass of matter in unit volume
motions and collisions create
Pressure
Pressure decrease with
Increasing altitude
Increased altitude causes
Fewer molecules to exert pressure at higher alts.
Low density (cold)=
Low pressure and vice versa
Strongly descending air produces a
High pressure at the surface
High pressure at the surface is called
Dynamic high
