The temperature of air depends on its location and time of day if it is above a body of water during day time its temperature will be lower the temperature of air above the land because water has the ability to absorb more heat than land so heat is not reflected back to the atmosphere there fore it keeps the air above it cooler, during night time in the absence of heat from the sun the heat absorbed by water and land are released land looses heat faster than water because it has absorbed lesser heat so the air above the land will have lower temperature during night time; water on the other hand during time continues to release heat since it absorbed more heat during the day, the heat that is released will warm the air above the water at night.
