Document Summary
Le/rn: high values (wetlands, shallow lakes) have low b and high a, low values (upland tundra, and forests) have high b and low a. Deep lakes: negative b (sensible heating of lake from the atmosphere in summer) high a of deep lake. Shallow lakes and wet lands: high latent/rn (high moisture, low resistance to evap, high a, low b. Shrub tundra: mid-range latent/rn (high moisture, some resistance) upland tundra and forest low latent/rn high resistance to evap- lichens low a high b, note: forest is lowest latent/rn. Deep lakes: lowest latent/rn (summer): energy used to heat water (so stored, and not available, winter: major latent heat source to atmosphere. Answer: energy balance differences of tundra and forest are probably too small to lock in the arctic front. The synoptic climate determines the location of the tree line in this incident.
