Second, the reasoning behind (27) is unclear. The left-hand side of (27) is an energy change rate and the right-hand side is the total energy input to snowpack over the time interval (this can largely be deduced from equations after (29)). The same disparity in units applies to (28) as well. Another weakness related to (27) is the oversimplified assumption of water equivalent as constant; this leads to possible computational divergence of snow temperature during snow accumulation. To correct this problem, we developed the following series of equations based on our concept of these processes and compared the results from our equations to those of Wigmosta et al. [1994]. We think a more precise formulation of the relationship presented in their equation (27) is
