What's new in models?
« on: September 11, 2015, 12:26:50 PM »
The sea ice orchestra

Since 2012, several new parameterisation schemes have been incorporated into sea ice models, including:

Melt ponds (accumulation of melt water on the ice surface).
Brine drainage through sea ice.
Atmospheric/oceanic form drag (obstructions to air/water flow caused by the variable ice morphology).
Anisotropic rheology (ice stresses in specific directions determined by ice floe shape).
Lateral melt which accounts for variable sea ice floes.

Huge advances have been made in recent years, but there is still some way to go before we can reliable simulate and predict the fate of the Arctic sea ice cover.

At the risk of hi-jacking this old thread...

1)  Why does SIPN try to predict September minimum extent instead of area?  Seems like area would be slightly easier to predict and might be slightly more interesting?

2)  Is there a good data source for May Melt Pond fraction?  Pretty much any number that has been gathered over "many" years that describes may melt ponds in some fashion?

3)  Are there other easy-to-use data sources for simple parameters?  June SST say?

The motivation here is that Rob Dekker has an interesting model that incorporates june area, june extent, and june snow cover.  Kinda makes you wonder if there are some other easy to grab parameters to see if they might be as useful as snow cover in making forecasts.
