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).
A subarctic climate has little precipitation, and monthly temperatures which are above 10 Â°C (50 Â°F) for one to three months of the year, with permafrost in large parts of the area due to the cold winters. Winters within subarctic climates usually include up to six months of temperatures averaging below 0 Â°C (32 Â°F). Normal is defined as the arithmetic average of a climate element (e.g. temperature) over a 30-year period. A 30 year period is used, as it is long enough to filter out any interannual variation or anomalies, but also short enough to be able to show longer climatic trends..
