Detailed Description
Modify the shelf base mass flux using a function of air temperature changes.
This modifier multiplies the input shelf base mass flux by a factor \( F \), which depends on the change in the global average near-surface air temperature =delta_T= read from an input file.
The parameterization described below is inspired by [Xu2013] with the relationship between air temperatures and subglacial runoff flux parameterized using a linear function (a fit to results of GCM simulations).
\[ F(\Delta T) = 1 + B \times (a \Delta T)^\alpha \times (\Delta T)^\beta. \]
Here \( a \), \( B \), \( \alpha \), and \( \beta \) are constants.
The paper [Xu2013] approximates the sub-shelf melt rate as a function of ocean temperature above the freezing point and the subglacial runoff.
We assume that the lag between the air and ocean temperatures is negligible and a change in air temperature is directly translated into a change in ocean temperature.
