Snow & Ice
10 important questions on Snow & Ice
What does it mean that snow is a 'passive' storage? What is then dynamic storage?
Smt about passive storage hence causing delay in modeling.
How can ROS cause floods?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Example: Rietholzbach Spring 2004
Daily average temps can mask smaller time scale differences that could cause melt/frost, hence alter the model results.
North facing slopes receive less radiation (remain snow covered longer), south facing slopes receive more radiation and will be warmer (also part of energy feedback, less snow will cause further radiation/temp increase).
Upper Sheep Creek experiment (Idaho) has massive SWE variations, how come? What is the effect?
What is a logical place for glaciers to form?
Flow of glacier ice:
What is plasticity?
When strains becomes too large, fractures can occur.
Glacier comparison of Mosnang (Rietholzback) and Gletsch (Rhone)
Record low Q during extreme dry summer 2003
Low storage due to drought
Gletsch:
Record high Q during extreme warm summer 2003
High glacier melt rates
What is a Jökulhlaup?
Iceland: glaciers on top of vulcanoes (that can suddenly can cause melt very efficiently) > very high Q peaks > mega-floods ipmact landscape formation > boulder (10x10 m) transport
Mass balance field of glaciers: where do positive, negative and zero mass balance occur?
Equilibrium line: b=0
Ablation zone: - mass balance, b<0
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
