  4. Air temperature data • Daily mean temperature is determined by two methods, (a) average of 24 hourly measurements (b) the average of the maximum and minimum temperatures for the day. • Daily temperature range is the difference between the max and min temperatures. • Monthly mean temperature is obtained from the average of the daily mean for the month • Annual mean temperature is the average of the monthly means • Annual temperature range is the difference between the coldest monthly mean and the warmest monthly mean

  5. CONTROLS OF TEMPERATURE • LATITUDE • SURFACE TYPE • ELEVATION AND ASPECT • DIFFERENTIAL HEATING OF LAND AND WATER. • OCEAN CURRENTS. • CLOUD COVER AND ALBEDO

  12. Differential Heating of Land and Water • AS WATER IS HEATED CONVECTION DISTRIBUTES THE HEAT THROUGH A LARGE MASS. • IN CONTRAST, HEAT DOES NOT PENETRATE DEEPLY INTO SOIL OR ROCK - HEAT CAN ONLY BE TRANSFERRED BY CONDUCTION. • NET RESULT IS THAT A RELATIVELY THICK LAYER OF WATER IS HEATED TO MODERATE TEMPERATURES, WHILE ONLY A THIN LAYER OF LAND IS HEATED TO MUCH HIGHER TEMPERATURES. • SPECIFIC HEAT (AMOUNT OF HEAT NEEDED TO RAISE THE TEMPERATURE OF ONE GRAM OF A SUBSTANCE 1 DEGREE CELSIUS) IS ALMOST THREE TIMES GREATER FOR WATER THAN FOR LAND
