Model of the energy content in the cryo-hydrologic system.

This model can be used to include the influence of cryo-hydrologic warming on the internal energy of the ice.

This model is based on

@article{PhillipsRajaramSteffan2010, author = {Phillips, T. and Rajaram, H. and Steffen, K.}, doi = {10.1029/2010GL044397}, journal = {Geophy. Res. Lett.}, number = {20}, pages = {1–5}, title = {{Cryo-hydrologic warming: A potential mechanism for rapid thermal response of ice sheets}}, volume = {37}, year = {2010} }

We assume that during the melt season the enthalpy in the cryo-hydrologic system is equal to the enthalpy of the ice with a fixed water fraction corresponding to the amount of water remaining in the system once all of the moving water drains out (0.5% by default). During the winter the CH system is allowed to cool.
