An explanation of fog

Fog is a thick cloud of tiny water droplets or ice crystals that forms near the ground, reducing visibility. It occurs when the air near the surface cools enough for water vapour to condense. Fog can be caused by various factors, including temperature changes, humidity levels, and geographical conditions.

Types of Fog:

1. Radiation Fog – Forms on clear, calm nights when the ground cools and causes the air above it to condense.

2. Advection Fog – Happens when warm, moist air moves over a cooler surface, causing condensation.

3. Upslope Fog – Develops as moist air is pushed up a slope or mountain, cooling as it rises.

4. Evaporation Fog – Forms when cold air moves over warm water, causing moisture to rise and condense.

5. Freezing Fog – Contains supercooled water droplets that freeze on contact with surfaces.

   
   

Effects of Fog:

• Reduces visibility, making travel dangerous.

• Creates a cool and damp atmosphere.

• Can disrupt air and road traffic.

• Enhances scenic beauty in some landscapes.
