Homework #6 Name _________________________
(Total 20 points)
Due to the fact our Earth spins, the Coriolis Effect gives weird responses to wind fields in
pressure fields. By now you should be familiar with contour maps. In a previous
homework, the contours were constant heights above sea level. Here the contours
represent constant pressures (or isobars). The areas denoted by the Capital H represent
High Pressure areas and the areas denoted by the capital L represent Low Pressure areas.
If our Earth had no spin, the wind field from Albany, NY to Dallas, TX would be almost
a straight line since high pressure always wants to flow directly to low pressure. This is
not the case on our Earth. Read the section in Chapter 8 related to the Coriolis Effect to
determine how winds would move.
For each of the following cities, fill in which direction the winds are blowing (ie. to the
North, to the East, etc.) (9 pts).
Seattle, WA _____________________
Bismarck, ND ___________________
Albany, NY ____________________
Dallas, TX ______________________
You may recall from the previous homework the question about what hill had the steepest
slope. To determine this, you simply looked to see which contour lines were closer
together. The same idea holds true here. Where you see contour lines closer together, the
wind fields are stronger.
From the map above place the 4 cities in order of least windy to most windy (9 pts).
Least windy _________________________
More windy _________________________
Even more windy _____________________
Most windy _________________________
For all low and high pressure systems, what general direction will they travel across the
central United States? (2 pts)
