(3.2) For what reasons is the meridional temperature gradient in the tropics weak, with temperatures roughly uniform-only varying from about 24° to 28°C- between 30°N and 30°S latitude? Select one: O a. The subtropical jet stream helps keep temperatures warm between the equator and 30° latitude. O b. The warm temperatures generally found in the tropics causes high evaporation rates, which in turn results in large amounts of water vapour in the tropical atmosphere and this in turn has a moderating effect on temperature extremes. O c. Due to the cosine rule, sunlight is quite strong between 30°N and S latitude, resulting in relatively warm temperatures everywhere. O d. The vigorous mixing produced by the strong Hadley circulation keeps the air well mixed in the tropics, resulting in relatively even temperatures.
