Week 3 Lab Activities
Adiabatic processes
Wind
Mid-latitude cyclones
Air pressure
2
It’s adiabatic
When heat is neither gained from, or lost to, the surrounding air, the process is called adiabatic
If increase pressure, then parcel compresses and temperature goes up even though didn’t add heat
If decrease pressure, then parcel expands and temperature goes down even though didn’t remove heat
Pressure decreases as altitude increases
Adiabatic Processes Exercise: compute temperatures as air parcel moves up over mountain and down other side
Explain results
Evaluate humidity changes and compute saturation mixing ratio
3
Wind
Draw wind flow arrows for upper atmosphere pressure map of US
Upper atmosphere has no friction
Wind flow follows isobars and doesn’t cross them
Northern Hemisphere, so
High pressure is clockwise
Low pressure is counterclockwise
Draw wind flow arrows on surface pressure map of US
Friction plays role
Wind flow crosses isobars
Northern Hemisphere, so
High pressure is clockwise and winds diverge
Low pressure is counterclockwise and winds converge
4
Mid-latitude cyclones
Label main parts of mid-latitude cyclone for Northern Hemisphere, including map and cross section, and answer questions
Draw in frontal boundaries for two hypothetical weather maps in the Northern Hemisphere and answer questions
5
Air Pressure
Interpret weather station symbols to read pressure and temperature for various examples
Draw lines of constant surface air pressure on a U.S. weather map at selected intervals as specified
