Textbook Question
Chapter 8, Problem 1E
Using Figure 8-2:
- a. Circle the area with the greatest pressure gradient.
- b. Use arrows to show the direction of pressure gradient force at a few locations. (These are typically drawn perpendicular to isobars.)
- c. Label a region where you would expect the lightest winds.
(a)
Expert Solution
To determine
The area with the greatest pressure gradient in Figure 8-2 using circle.
Answer to Problem 1E
The map showing the area with the greatest pressure gradient is given below:
Explanation of Solution
“The magnitude of pressure gradient force is a function of the pressure difference between two points and air density.”
The map given in Figure 8-2 shows isobars, which are lines that connect areas with equal pressure. Closer isobars represent areas with higher pressure gradient. On the basis of this, the greatest pressure gradient is marked using a circle in the map towards the top right side of the Figure.
(b)
Expert Solution
To determine
The direction of pressure gradient force at some locations in Figure 8-2 using arrows.
Answer to Problem 1E
The map with the direction of pressure gradient force at some locations indicated using arrows is shown below:
Explanation of Solution
The direction of pressure gradient force is usually drawn perpendicular to the isobars. The pressure gradient force is generally directed from the region of high pressure to lower pressure.
(c)
Expert Solution
To determine
The region where the lightest winds are expected to occur in Figure 8-2.
Answer to Problem 1E
The area expected to experience the lightest winds is labelled in the map given below:
Explanation of Solution
The isobars that are widely-spaced generally denote a gradual pressure gradient and lighter winds whereas the closely-spaced isobars denote steep pressure gradient and stronger winds.

In Sequoia National Park, why does soil moisture increase in April even though precipitation totals are on average lower in April than in March?
The continents are net importers of precipitation from the oceans. We know this because, while only 15% of global evaporation occurs from the continents, the continents receive 23% of the globe’s precipitation. How is this discrepancy sustainable without the continents filling up with water and the oceans emptying out?

- There is an old axiom (a self-evident or universally recognized truth) of economics that “There is no such thing as a free lunch”. In the United States, stringent, enforced water quality laws and regulations provide a high level of protection of our waters. This is accomplished at a significant cost. For example, (sewage treatment plants use 2% of the electricity produced in the United States. This high level of protection increases the cost of goods manufactured in the United States compared to other nations such as China where standards are lower, enforcement a bit lax and in some cases, non-existent. What five (5) things could be done to “level the playing field” so that all manufacturers must provide the same degree of water quality protection no matter where in the world they are located? include how each of your ideas will be implemented (ex: which organization will be provided the power and resources to make sure each idea happens).
