- Suppose you are camping along the eastern side of a small mountain. Smoke from your campfire is blowing uphill. Meanwhile, a friend camping on the western side of the same hill finds her campfire smoke drifting downhill. Are you and your friend cooking breakfast or dinner? How did the direction of the smoke from your campfire and Fig. 9.23 help you come up with your answer?
- The region of southwestern Ontario along a line from Detroit to Toronto is bounded by Lake Huron to the north and Lake Erie to the south. This narrow strip of land often experiences mid-afternoon thunderstorm in summertime. Explain the process in the light of lake breeze convergence. Take into consideration of following points while describing the process.
a) What are land and sea breezes

3. In the autumn, Santa Ana winds blowing into Southern California often cause air temperatures in cities around Los Angeles to rise above 90°F. Look back at Fig. 9.29 and come up with two possible reasons why on August 8, 1978, a Santa Ana–type wind blowing downhill into Red Bluff, California, was able to raise the air temperature there to 119°F —an air temperature typically much higher than those experienced during Santa Ana conditions in Southern California.
