Atmospheric And Cryospheric Processes Flashcards
(12 cards)
What is the ITZC and what weather occurs here?
Inter tropical convergence zone
Warm moist air rises, cools, condenses
What happens where Ferrel and Hadley meet?
Air sinks, and it is warm and dry. Dry weather
Which part of the atmospheric circulation model effects britan
The Ferrel cell affects us in britan, brings warm south westerlies in north, north westerlies in the south.
Wind picks up moisture over oceans
Cryospheric processes
Accumulation- build up of a glacier from snow compacting to ice
Ablation- melting of ice, during summer months
How many glacial periods have there been in earths history?
5 major glacial periods
Most recent started 2.58 million years ago and continues today alternating interglacial/glacial
Called quaternary glaciation
How is permafrost formed?
Air temperatures are so low freeze soil with groundwater
Rain
Cloud become too heavy to stay suspended and fall to the ground
Drizzle
Very small droplets of water from low level stratus clouds
Snow
Solid precipitation of ice crystals and snowflakes below 0c
Sleet
Solid precipitation that melts while it falls
Hail
Solid precipitation in the form of balls of ice
Differences between types of precipitation
How they are formed
