Why does the annual temperature range increase as latitude increases?
The annual temperature range increases with increasing latitude. There is little or no seasonal change at the equator. Water has a higher specific heat, it takes more energy to heat a gram of water than to heat a gram of soil. In addition, some of the incoming energy is used to evaporate instead of hot water.
Why does the annual temperature range depend on latitude?
The angle of sunlight to the surface also depends on latitude. In general, at higher latitudes the sun is lower on the horizon, which weakens sunlight intensity and produces cooler temperatures.
Why do the warmest temperatures occur in the middle of continents?
Continental climates often have significant annual variation in temperature (hot summers and cold winters). They tend to occur in the middle latitudes (40 to 55 north), where prevailing winds blow over land and temperatures are not moderated by bodies of water such as oceans or seas.
Why do the highest temperatures occur at the equator?
More heat from the Sun is received near the equator than near the North and South Poles, where the angle of the Sun's rays is lower.
The four controls on atmospheric temperature are (1) differential heating of land and water; (2) ocean currents; (3) altitude and geographic position; and (4) cloud cover and albedo (Pearson, The Atmosphere).
