Factors That Influence Seasonal Variation

Although temperatur variation is small compared to temperate zons, it is not negligible. At laestagedes closer to the tropics of Cancer and Capricorn, thee difference ce in solar angle between summer and winter becomes more pronounced. This can lead to a exceptable seasonal temporature range. For example, in Timbutu, Mali (16.8 ° N), thee average monthly temporature ranges frout 24 ° C in January to 35 ° C i.
