Land-Water Heating Differential

The sun's energy will strike equally at two places at the same latitude assuming the atmospheric conditions are the same. If one of these locations is near a large body of water and the other is hundreds of miles inland, there will likely be a seasonal contrast in temperature between these two locations.

Traverse City (44°N) and Eugene, OR (44°N) are at nearly the same latitude but are far different in longitude and environmental setting. The following table displays the average maximum monthly temperatures for the two cities:

1-The average annual temperature is calculated by adding the twelve monthly averages and dividing by 12. What is the average annual temperature of Traverse City? Don't forget the units.

2-The average annual temperature is calculated by adding the twelve monthly averages and dividing by 12. What is the average annual temperature of Eugene? Don't forget the units.

3-The annual range of temperature is calculated by subtracting the lowest average monthly temperature from the highest average monthly temperature. What is the annual range of temperature for Traverse City? Don't forget the units.

4-The annual range of temperature is calculated by subtracting the lowest average monthly temperature from the highest average monthly temperature. What is the annual range of temperature for Eugene? Don't forget the units.
