Initial Formation of Polar Lows in the High-latitude Atmosphere: A Modeling Based Study Approach

A regional mathematical model of the lower atmosphere’s wind system, built previously at the Polar Geophysical Institute, is used to explore the early stages of the genesis of polar lows at European Arctic latitudes. The mathematical model generates three-dimensional distributions of atmospheric parameters in the height range of 0 to 15 km over a constrained region of the Earth’s surface by numerically solving nonsimplified gas dynamic equations. The establishment of a polar low can be triggered by the emergence of a convexity in the arctic front’s shape during a one-day period, according to simulation data.
