Sea ice formation dynamics

Seeding the thread.  Moved from melt season.

Here's a link to a Chris Reynolds discussion on ice growth calculations, and another to a post in his "Slow Transition" thread about Lebedev and Billelo and related issues.

I would ask that further discussion of this very important issue continue in a different existing thread, or start a new one if needed.
Make a search for Lebedev and Billelo to help in locating a suitable venue.

Glen Koehler,
I think that the formula given by John_The_Elder in the previous post: "Thickness (cm) = 1.33 * FDD (°C)^0.58", is relative to a starting situation without ice. If at the beginning there is already an ice thickness to use the formula you have to add to the FDD the value that gives the thickness already present (and the influence of the thickness in the formula is given by the exponent 0.58).

Nico Sun quotes this formula in his webpage for FDD   https://cryospherecomputing.tk/index.html

The source quoted is  "Lebedev - 1938". One wonders what research / testing has been on this formula since 1938.

I've posted the Lebedev formulat a couple of times previously over the years.  It's pretty empirical and does factor in the ice thickness.  Like many such things, it isn't precise, but does provide scale.

Thank you jdallen for opening the thread.
I am sure there is also lots of new information from Mosaic about the subject.

Glen, to be honest I'd rather this thread be kept for freezing processes/formulas. There is another older thread about melting physics that you can revive. It's not the same at all because of the effects of bottom melting and of insolation.
