Seasonal Uniformity Tropical climate are defined by the absence of a cold season, which means that temperature differences between seasons are generally small in the tropics This can be indicated by the mean annual range (the mean of the coolest and the hottest month of the year) Next figure shows a map with annual range of temperature. Over the ocean is Sea surface temperature (SST) which is very close to air temperature

Temperature of stations at sea level and near the ocean 1. Clearly the annual range of temperature ‘follows’ the sun (increase with latitude) 2. Local factors are important too: Ex. Mozambique and Beira: 5 o latitude apart and have approximately the same range: influence of the Agulhas current 3. Carnarvon (W Australia) is colder than Durban that is 5 o S. Carnarvon is near a cold ocean current and Durban near a warm one

Spatial Uniformity of Temperature Temperatures are very uniform in tropical areas: 1.There are only very small differences in the amount of net radiation received. Between the Equator and 10o latitude almost the same amount is received in all places 2.Most of the tropics consist of ocean surfaces, great heat storage reservoirs. Cold air masses only form over cool currents. Advection of cold air is therefore very rare in the tropics.

Did you know… Southern Amazon can be less than 10 o C? This phenomenon is known as ‘friagem’ or cold episodes. They occur when polar masses penetrate into the continent east of the Andes Minimum temperature was as low as 9.2 o C (48.56 F) in Vilhena, Rondonia, Amazon on July 25 2009
