Exponential ridge-draft model
= Exponential ridge-draft model
{title2=$n(H)=Be^{-bH}\mathbf1_{\{H\ge h_0\}}$}
Here $n(H)dH$ is the expected number of ridge peaks per track length with <sea-ice draft> in $[H,H+dH]$. If total line density is $\mu$ and mean peak draft is $h_m>h_0$, integration gives $b=1/(h_m-h_0)$ and $B=\mu b e^{bh_0}$. The normalized peak draft has a shifted <exponential distribution>. This is a model over a specified draft range, not a universal description of every ridge.
