Begin in the west and move across the map to the east, briefly explaining why the actual 16°C (60°F) isotherm deviates from the hypothetical.

Using a straightedge, draw a line across the July temperature map (Map T-28b; shown in color at the back of the Lab Manual) from point “A” to point “B.” This reference line can be thought of as the “hypothetical” position of the 16°C (60°F) isotherm were there no land–water contrasts, ocean currents, and so on. Compare the actual 16°C isotherm, with the line you have just drawn. In places where the actual 16°C isotherm is south of the hypothetical line, temperatures are lower than expected; in places where the actual 16°C isotherm is north of the hypothetical line, temperatures are higher than expected.


Deflection to south along west coast of North America due to cool current.
Deflection to north over North America due to warming of land in summer.
Even across Atlantic Ocean.
Deflection to north over Eurasia due to warming of land in summer.
