Description
A constant is usually prescribed to limit the value of the modeled mixing length. Tests suggested that TC intensity is sensitive to the limit value used. We introduce an option to use PBLH and wind-shear dependent mixing length limits in SATMEDMF scheme. HAFSv2.2 tests have shown that using variable limits can improve TC intensity errors and rapid intensification.
Solution
Minor code changes. Several lines are added to make calculations. The default setting remains the same.
