Modeling sea ice thickness
In this paper, we present a self contained review on the modeling of sea ice thickness distribution. This is an important quantity arising and contributing to global climate changes. We present the various pde describing it, which are strongly non linear. Detailed mathematical analysis will be reported elsewhere. The utility of this quantity is of course to set up a global analysis of sea, ice ...
متن کاملSea-Ice Thickness Measurement:
Helicopter-borne electromagnetic (HEM) induction systems provide a means to measure sea ice thickness along flight paths covering a large area in a short period of time, and make the data available in real-time for incorporation into operational ice charts. Ice surface elevation profiles are also collected with a laser altimeter contained in the system. With the introduction of the fix-mounted ...
متن کاملTheory of the Sea Ice Thickness Distribution.
We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution g(h) from Thorndike et al. into a Fokker-Planck-like conservation law. The steady solution is g(h)=N(q)h(q)e(-h/H), where q and H are expressible in terms of moments over the transition probabilities between thickness categories. The solution exhibits the functional form ...
متن کاملSea Ice Thickness Data : the Many Vs
During May 1988 a 1230-m ice thickness profile was drilled across a floe in Fram Strait. The probability density function of this data set corresponds closely to extensive ice draft measurements from submarines and the thickness distribution of floes sampled randomly in the area. The observed similarity is attributed to the topography of the pack ice in Fram Strait where each floe is composed o...
متن کاملSea ice thickness and recent Arctic warming
The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations using the EC-Earth atmospheric model (Integrated Forecast System) are performed and analyzed to quantify the atmospheric impacts of Arctic sea...
