*This sheet is intended as a HELP; learning is more than memorization of terms.
will be derived from both the lectures and the readings (chapters 5-8 in McKnight and Hess’ 10th
The lectures and readings contain many facts, but the point of the course is to have you
gain an understanding of how the facts fit together.
*The exam will have 50 multiple choice questions and 5 fill-in-the-blank questions.
The exam will
count 165 points out of 1,000 in the course.
Terms from readings and lectures
pressure, atmospheric pressure
pressure, density, and temperature as they relate to each other
barometer, millibar, isobar, high, low, ridge, trough
wind, updrafts, downdrafts
forces causing wind: pressure gradient, Coriolis, friction
how the forces interact to create wind
the friction layer
geostrophic wind versus surface wind
Can you determine the direction of the wind looking at a map of isobars?
cyclones and anticyclones
the surface and upper air flow in cyclones and anticyclones (Fig. 5-9)
descending air in anticyclones, ascending air in anticyclones and its importance
knots versus miles per hour (you will not need to convert)
the geography of wind speeds (Fig 5-11)
Gist of “Wind Power” page
Nature of pressure/height relationship in Table 5-1
the wind and pressure belts of the Earth:
intertropical convergence zone, trade winds, subtropical
high, westerlies, polar front, polar easterlies, polar high, Hadley cells (Fig. 5-14)
***Note: This figure connects many concepts and is very important***
horse latitudes, doldrums
upper westerlies, polar front jet stream, subtropical jet stream, Rossby waves
seasonal migration of the wind and pressure belts
