Starches make up a large part of the carbohydrates consumed by Americans. Foods made from starchy vegetables, grains or their flours, such as french fries, baked potatoes, breads, pasta, rice, cookies and cakes, are all high in starches.
However, the average annual temperature is similar to that of the other tropical wet climates. Mean monthly temperatures in the Tropical Wet/Dry climate range from 18 o C (64.4 o F) to above 25 o C (77 o F).
Continental (Group D) climates are found in most of the North American interior from about 40Â°N to 70Â°N. In this climate, summers are cool-to-warm and winters are very cold and stormy. The average temperature of the warmest month is higher than 10Â°C (50Â°F) and the coldest month is below -3Â°C (-27Â°F).he subpolar climate is found between the humid continental and the polar tundra climates (Figure 17.22). This climate is dominated by long, very cold winters with very little precipitation. Continental polar air masses form when air stagnates in this zone.
