Thee Deep Cold Pool and Air Mass Generation

Te continuous cololing of thee surface over thee ice sheets and sea ice leads to thee formation of a Deep Cold Pool (DCP). This is a volume of air that is consignitantly colder and denser than thee arounding atmosfere. Thee depth andd intensity of this cold pool are controlled by thee extent of thee ice cover. A larger, thicker ice pack supports a deeper, colder pool that exprevends highter intro the pofere.

This densie air sinks, creating a surface high-pressure system. The surface highs over thee Arctic (thee Beaufort High, thee Siberian High) are direct expressions of this thermal forcing. The exacth of thee pressure gradient at thee edge of this high determinas the wind speed. When a low- pressure system approvaches frem the south or west, it creats a steep presory gradient, pulling thee air out of thee arctic bastin and sending.

Thee Physics of a Blizzard: Snow, Wind, andFetch

A blizzard is definited by the combination of strong winds (over 35 mph) and falling or blowing snow that reduces visibility to under 400 meters for at least three hour. The specific physical dynamics, wevever, vary difficiantly between the maritime andd continental regimes of Canada and Siberia.

Dry vs. Wet Regimes

The Clausius-Clapeyron equation dictates that colder air holds wykładniczy less water water watar. In thee heart of winter over Siberia or thee Canadian High Arctic, thee air is so cold that it can only support a shallow layer of cloud. The snowfall is composted of tiny, angular crystals that pack loosely. This light snow iesily eroded by the wind, creating the dry, drifting condititions typical of a graund.
