GEOG 1120 Lecture Notes - Cold Front, Nimbostratus Cloud, Stratus Cloud
Document Summary
Fog is clouds in direct contact with the ground. Less than 1 km is visible at a distance. Example: cold ocean current brings cold air across coast of vancouver to a pool of warm air coming towards north america. However it is in direct contact with cold water and temperature begins to drop by process of cooling. Reaches dew point temperature, becomes saturated, becomes fog and develops right along our coastline. b) Example: at night, no clouds, the best setting. Under cloudless condition, earth is losing heat to outer space fast, and infrared radiation by earth goes up. Overnight, heat alters fast and ground becomes really cold really fast and air directly above cools at fast rate too. Example: landmass on left side, body of water on right side. Cold air moving from left to right (towards body of water, in direct contact).
