A fog is just a cloud at the ground. Fog formation can occur in two ways. First, the air is cooled to the dew point which leads to the formation of fog droplets. When the air temperature is the same as the dew point temperature, condensation occurs on tiny particles floating in the air. The second method of fog formation requires water to evaporate from the surface into the air, raising the dew point until condensation occurs.
“Geography Cat believes that both are very damaging, but that the primary impacts of a tropical storm are more damaging than the secondary impacts. For example, the most devastating primary impact of Typhoon Haiyan, which hit the Philippines in 2013, was the death of 6 300 people.”
