用于层流-湍流过渡通量参数化的简单GlaDS ISSM设置matlab代码.zip

# ISSM model runs A simple example of a suite of ISSM-GlaDS runs for each of the sheet-flow parameterizations in [Hill et al., 2023](https://doi.org/10.1017/jog.2023.103). The GlaDS setup consists of a 100 km x 25 km synthetic ice-sheet margin with constant basal melt (0.05 m/year) and seasonally-varying inputs to 50 randomly positioned moulins. The model is run for two years to reach an approximate dynamic steady state. Each run should only take a few minutes. The script `synthetic/run_suite.m` runs all five simulations. There are a few basic plotting scripts in the `analysis/` folder. ## Sheet-flow parameterizations The sheet-flow parameterization is the only difference between the five cases. Parameters are set as follows Case | `sheet_alpha` | `sheet_beta` | `istransition` | `omega` | `sheet_conductivity` ------------------- | --------------| ------------ | -------------- | ------- | ------------------------ 1 (Turbulent 5/4) | 5/4 | 3/2 | 0 | 0 | 0.0071 2 (Turbulent 3/2) | 3/2 | 3/2 | 0 | 0 | 0.0134 3 (Laminar) | 3 | 2 | 0 | 0 | 0.05 4 (Transition 5/4) | 5/4 | 2 | 1 | 1/2000 | 0.05 5 (Transition 5/4) | 3/2 | 2 | 1 | 1/2000 | 0.05 Channel parameters do not vary between runs.
