Understanding the Weather Chapter 5 Review Condensation Nuclei: Tiny particles upon whose surfaces condensation of water vapor begins in the atmosphere. Small nuclei less than 0.2 µm in radius are called Aitken nuclei ; those with radii between 0.2 and 1 µm are large nuclei, while giant nuclei have radii larger than 1 µm. Radiational Cooling: The process by which the earth’s surface and adjacent air cool by emitting infrared radiation. Dew and Frost Formation: Types of Fog: Radiation Fog - Fog produced over land when radiational cooling reduces the air temperature to or below its dew point. It is also known as ground fog or valley fog . Advection Fog - Occurs when warm, moist air moves over a cold surface and the air cools to below its dewpoint. Upslope Fog - Fog formed as moist, stable air flows upward over a topographic barrier. Evaporation Fog - Fog produced when sufficient water vapor is added to the air by evaporation, and the moist air mixes with relatively drier air. The two common types are steam fog, which forms when cold air moves over warm water, and frontal fog, which forms as warm raindrops evaporate in a cool air mass. Clouds and Satellite Imagery:
