ATSC 113 Snow Final Exam Review
Questions with Correct Answers
Low pressure system/Cyclone - Answer-BAD Weather
-High percipitation
-Strong winds
-Low Visability
-
High pressure systems/anti-cyclone - Answer-Good Weather
-Dry conditions
-Little percipitation
-Clear skys
Wind Chill - Answer-Not actual Temperature, but what it feels like on the skin
With cold fronts - Answer-Heavy snow Fall
Blowing snow
Clouds and fog
Blizzard Conditions
With Warm fronts - Answer-Blizzard Conditions
Katabatic Wind - Answer-downslope movement of air that occurs in the absence of
larger-scale wind flows.
Snow density - Answer-the amount or mass of ice and liquid water per volume.
Faceted crystals, - Answer-produced when a strong vertical temperature gradient exists.
The water vapour is moving quickly, and crystal growth happens quickly. The rule of
thumb is that faceting takes place when the temperature gradient is larger than 1°C per
10 cm depth, or equivalently 10°C per metre.
Rounded crystals - Answer-produced when temperature gradients are weak, water
vapour moves slowly, and crystal growth happens slowly. Typical rounding occurs when
the vertical temperature gradient within the snowpack is less than 1°C per 10 cm depth,
or equivalently, 10°C per metre.
hand-hardness test - Answer-fist, four fingers, one finger, pencil, and knife.
Coastal Snow Climate - Answer--Frequent snowfall, with relatively large amounts in
each storm
-High density newly fallen snow
