Factors Governing the Diurnal Cycle


Along with wind, clouds and moisture strongly affect daytime and nighttime temperatures. Some aspects of clouds and moisture help explain the variations in temperature from place to place; other aspects are responsible for large changes in temperature from day to day. This module discusses the effect on surface temperatures of soil type, surface moisture, and clouds.

Learning Objectives

  1. To understand the effect of dew point temperature on the nighttime minimum temperature.
  2. To understand the effect of fog on temperatures.
  3. To understand the effect of clouds on temperatures.
  4. To understand the effect of soil type on temperatures.
  5. To be able to apply this knowledge to weather forecasting.
