The Science of Fog

One of the challenges that pilots face when flying is navigating through misty conditions, especially foggy weather. Understanding the science behind fog is crucial for safe flying operations. Fog is importantly a cloud that forms near the ground when air cools to the point where it can no longer hold all its water vapor. This causes the vapor to condense into tiny water droplets, creating a misty or foggy appearance.

Types of Fog

  • Radiation fog: forms on clear nights when the ground loses heat rapidly due to radiation and the air above becomes cooler. This type of fog is common in valleys and low-lying areas.
  • Advection fog: occurs when warm, moist air moves over a cool surface, causing the air to cool and the vapor to condense into fog. This type is often seen in coastal regions.
  • Upslope fog: forms when moist air is pushed up along elevated terrain, cooling and condensing into fog as it rises.
  • Evaporation fog: arises when cold air moves over a warmer water surface, causing the water to evaporate and then condense into fog.
  • Freezing fog: occurs when fog droplets freeze upon contact with a surface that is at or below freezing temperature, creating icy conditions.

Any pilot flying through fog must be aware of the different types and their characteristics to navigate safely.
