CHAPTER 13 3, 5, 8
3. The accompanying map is a simplified surface weather map for April 2, 2011 on which the centers of three pressure cells are numbered.
a. Identify which of the pressure cells are anticyclones highs and which are cyclones lows.
The anticyclones highs occur in high pressure cells and flow outward and clockwise. The cyclones lows are in low pressure systems and are blow inward and counterclockwise.
b. Which pressure center has the steepest pressure gradient and therefore the strongest winds. Low pressure
c. Refer to figure 13.2 to determine whether pressure center 3 should be considered strong or weak. strong
5. If you live in the Northern Hemisphere and are directly west of the center of a cyclone, what is the probable wind direction at your location? What if you were west of an anticyclone? Counterclockwise; clockwise
8. It is late afternoon on a warm summer day and you are enjoying some time at the beach. Until the last hour or two, winds were calm. Then a breeze began to develop. Is it more likely a cool breeze from the water or a warm breeze from the adjacent land area? Explain A cool breeze from the water because the low and high pressure over the oceans effects the winds over land.
Chapter 14: 2, 3, 6, 8
2. Refer to the Figure 14.4 to answer these questions.
a. Thunder Bay and Marquette are both on the shore of Lake Superior, yet Marquette gets much more snow than Thunder Bay. Why is this the case? The location of the air masses and because of the lake-effect snows.
b. Notice the narrow, north-south zone of relatively heavy snow east of Pittsburgh and Charleston. This area is not affected by the Great Lakes. Speculate on the likely reason for the higher snowfall here. Does your answer explain the shape of this snowy area? There is probably higher snow fall in that area because of the low pressure system and the maritime polar air which explains the shape, since it produces a storm characterized by snow.
3. If you hear that a cyclone is approaching, should you immediately seek shelter? Why or why not? Yes, because cyclones signal low pressure which could mean heavy rain and storms.
6.The accompanying table lists the number of tornadoes reported in the US by decade. Propose a reason to explain why the totals for the 1990s and 2000s are so much higher than for the 1950s and 1960s. More technology to identify tornadoes and track them.
8. A television meteorologist is able to inform viewers about the intensity of an approaching hurricane. However, the meteorologist can report the intensity of a tornado only after it has occurred. Why is this the case? A tornado forms as a result of a severe thunderstorm and hurricanes form in the ocean.
