Fog dew point spread

WebOct 11, 2024 · As a rule of thumb, fog forms when temperatures drop to within 5 degrees Fahrenheit (2 degrees Celsius) of the air mass’s dew point. By the way, dew points correspond to humidity. The higher the … WebFog is often described as a stratus cloud resting near the ground. Fog forms when the temperature and dew point of the air approach the same value (i. e, dew-point spread is less than 5°F) either through cooling of the air (producing advection, radiation, or upslope fog) or by adding enough moisture to raise the dew point (producing steam or frontal fog).
