Synoptic Lesson 1

This is form Sikora's Lesson 1 Notes

TermDefinition
Empiricism and Theoretical Dynamics The two basic ways to group phenomena within the atmosphere?
Empirical Method The ability to sense a given phenomena.
Mesoscale Describes a phenomena sensed by weather radars that was smaller than the synoptic scale but larger than the microscale. (1950s)
Theoretical Method Based on Atmospheric forces/accelerations from the governing equations that have different importance at different scales.
What can be disregarded in the synoptic scale? Vertical accelerations and ageostrophic advenction.
What can be disregarded for the microscale? Coriolis acceleration.
What cannot be simplified in the mesoscale? Governing equations.
Traits of Macro α (planetary scale) - Hori spatial scales > 10,000 km - Ex: Small frequency waves
Traits of Macro β (synoptic scale) - Hori scales between 10,000 km and 2,000 km. - Ex: Extra-tropical cyclone
Traits of Meso α - Hori scales between 2,000 km and 200 km. - Ex: Hurricanes, polar mesoscale cyclones, frontal zones.
Traits of Meso β - Hori scales between 200 km and 20 km -Ex: Mesoscale convective complexes
Traits of Meso γ - Hori scales between 20 km and 2 km - Ex: T-storms, some larger atmo. gravity waves
Traits of Micro α - Hori scales between 2 km and 0.2 km - Ex: Boundary layer cumulus clouds, large scale tornadoes, short atmo. gravity waves
Traits of Micro β - Hori scales between 0.2 km and 0.02 km - Ex: Dust devils and thermals
Traits of Micro γ - Hori scales between 0.02 km and 0.002 km - Ex: Surface layer plumes
Traits of Micro δ - Hori scales < 0.002 km - Ex: Small-scale mechanical turbulence
Most of Kinetic Energy exists where in the atmo.? It exists in the planetary and synoptic scales are any given time.
1. Larger scales of motion are what? 2. Smallest scales of motion are what? (Based on atmo. KE) 1. Sources of atmo. KE 2. Sinks of KE.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
