Supercooled droplets - Study guides, Class notes & Summaries

ATSC 113 Midterm 1 Exam Questions with All Correct Answers Already Tested What are supercooled droplets? - Answer- Can be liquid between -40C and 0C but the liquid droplets freeze almost instantly when they touch something soild and cold What happens to precipitation when you climb above -40C? - Answer- All liquid water is already frozen into ice crystals, so there is not normally an icing hazard at these altitudes because they don't stick to the plane In the summer where is the hig...

WX 201 Exam 2 with correct Answers (Graded A) Generally, the concentration of condensation nuclei is greater over the oceans than over land. False If a city receives 24 inches of snow, it is the equivalent to 18 inches of rain. False An important factor in the production of rain by the collision-coalescence process is the number of ice crystals in the cloud. False In a cloud composed of water droplets and ice crystals, the saturation vapor pressure is less over the droplets th...

What is RVR? : Runway Visual Range When is RVR included? : RVR is included if the visibility is 1 SM or less, and/or RVR is 6000ft or less. In reference to icing what is a low catch rate/ slow rate of catch? What type of ice is associated with it? : Less chance of ice due to smaller water droplets Associated with Rime Icing In reference to icing what is a High Rate of Catch? What type of ice is associated with it? : Higher chance of ice due to large droplets Associated with clear ice...

GEOG 1900 Chapter 7: Precipitation; Questions and Answers 100% Solved Aggregation The joining of two ice crystals to form a single, larger one. - Occurs most easily when ice crystals have a thin coating of liquid water to make them more "adhesive" (this means that adhesion is more common the warmer end of cold clouds since water is not likely to be present in the colder [below 0 C] portion) Bergeron Process The process by which rain is formed in cold clouds. - Underlying principle is...

ATSC 113 Final Exam Questions and Answers All Correct What do snowcats do? - Answer- Churns, tills, compacts top 10-15cm of snow increasing snow density & hardness It is best to let piste harden for ____ - Answer- harden for max time (right after closing). Hardening is fastest when snow T is closest to 0C More effective to maintain piste when snow is more dense How do you harden the piste for racing? - Answer- 1. Snow cats are used to compact the surface. 2. Man-made snow w/ higher...
