100
For a low pressure to strengthen, there must be upper level convergence or divergence.
What is divergence
100
If there is upper level convergence, surface highs will get stronger or weaker
What is stronger
100
Low pressure systems send cold or warm air northward
What is warm air
200
The spin in the atmosphere is called this:
What are vorticity
200
When a parcel moves out of a trough toward a ridge, it's vorticity goes up or down
What is down
200
We get upper air convergence or divergence to the east (right side) of a trough.
What is divergence
300
The band of fast winds in the upper air flow
What is the jet stream
300
The area of faster winds within the jet stream
What are jet streaks
300
Jet streams on an upper level map can be located by either looking at the upper level winds or by this method
What are tight gradients
400
There are general types of these upper level waves in the atmosphere.
What are long and short waves
400
Short waves are generally identified by this feature in the upper air pattern.
What is a maximum of vorticity
400
This type of wave spawns more intense surface storm systems.
What is the short wave
500
Jet streaks are often associated with sunny weather, colder weather, or stormy weather
What is stormy
500
Surface lows would tend to weaken if under the upper air: east of a ridge, east of a trough, over the trough
What is east of a ridge
500
They are the two types of flows in the upper atmosphere.
What are zonal and high amplitude
