GY 101 Exam 2 UPDATED ACTUAL Questions and CORRECT Answers
1. Global Scale Atmospheric features that cover large portions of earth and maintained over and
extensive time period
2. Synoptic Scale High and low pressure patterns over large parts of continents
3. Mesoscale Cover just a few square km to hundreds of square km
4. Microscale Very small scale, like ripples that form on snow or a sandy beach
5. Single-cell Model Describes the general movement of the atmosphere, proposed by George Hadley
6. Zonal Winds Move in an east/west or west/east direction
7. Meridional Winds Move in north/south or south/north direction
8. Three-cell Model Model that divides each hemisphere into 3 cells: The Hadley, Ferrel and Polar cells
9. Hadley Cell Circulates air between the tropics and subtropics
10. Ferrel Cell Circulates air in the middle latitudes
11. Polar Cell Circulates air at the poles
12. Intertropical Con- A zone of low pressure at the equator due to intense heating. Also referred to as
vergence Zone the Equatorial Low
(ITCZ)
13. Subtropical Large band of high pressure
Highs
14. NE Trade Winds Winds in the N Hemishere deflected to the right
15. SE Trade Winds Winds in the S Hemisphere deflected to the left
16. Subpolar Lows Areas of low pressure

, GY 101 Exam 2 UPDATED ACTUAL Questions and CORRECT Answers
17. Westerlies Caused by air moving from the subtropical highs towards the subpolar lows by the
Coriolis Effect
18. Polar Highs Areas of high pressure
19. Polar Easterlies Air moving towards the equator that is deflected by the Coriolis
20. Semipermanent Areas of high/low pressure that undergo seasonal changes in position and
Pressure Cells strength
21. Polar Fronts Strong boundaries that occur between warm and cold air
22. Polar Jet Stream A fast stream of air that exists in the upper troposphere, winds are twice as strong
in winter as summer
23. Subtropical Jet A mechanism to transport moisture and energy from the tropics towards the poles
Stream
24. Rossby Waves Largest of the atmospheric waves, circle the globe at any one time and each have
its own wavelength and amplitude
25. Air Masses Contain uniform temperature and humidity characteristics
26. Fronts Boundaries between different air masses, usually linked to midlatitude cyclones
27. Source Regions Areas of the globe where air masses form. Air masses will reflect the temperature
and humidity characteristics of the source region.
28. Continental Polar Air masses that form over large, high latitude land masses, such as N Canada and
(cP) Liberia, typically stable
29. Continental Arc- Air masses that contain extremely cold and dry conditions
tic (cA)
30. Arctic Front The boundary between cA and cP
