Radiation fog a-level geography essay

A microclimate is the distinctive climate of a smallscale area, such as a garden, park, valley or part of a city. The weather variables in a microclimate, such as temperature, rainfall, wind or humidity, may be subtly different from the conditions prevailing over the area as a whole and from those that might be reasonably expected under certain The fog formed due to mixing of warm moist air and cold air due to arrival of warm and moist air over cold ground surface is called advectional radiation fog.

There are certain necessary conditions for the origin of advection radiation fog. e. g. : fog that forms on clear, calm nights when the land surface loses heat rapidly (by radiation); the air above is cooled to below its dew point and condensation takes place. rainfall a form of precipitation in which separate drops of Lower levels of the air are originally warm and contain hygroscopic nuclei, if rapid cooling of the ground occurs radiation fog then forms. The fog may become thicker leading to smog if a temperature inversion occurs, where cold air at the surface is trapped beneath warmer air lying above it (the reverse if normal atmospheric conditions).

Radiation fog is a thin layer that forms because land cools down overnight. When the dew point is reached, and condensation occurs the fog moves slowly upwards. Radiation fog is common at lakes, harbours and in river valleys 1. Morning sunrise the suns rays heat the ground beneath the fog and the water droplets evaporate to become water vapour. This effect spreads up through the fog and the fog dissipates. This is often called burning off the fog.

2. Strong winds these can cause turbulence within the fog and disperse the water droplets.
