Norway opens first polar low forecast / News / The Foreigner

Norway opens first polar low forecast. Norwegian scientists can almost certainly measure areas of polar lows for the first time-ever, they announce. New website barentswatch.no (external link, in Norwegian) is designed to give authorities, key decision-makers, and ordinary members of the public easier access to information about coastal and ocean areas. Polar lows, also previously defined as polar mesoscale vortexes, Arctic hurricanes, Arctic lows, and cold air depressions, often have near-surface winds of at least 38mph (17m).

Norway opens first polar low forecast

Norwegian scientists can almost certainly measure areas of polar lows for the first time-ever, they announce.

New website barentswatch.no (external link, in Norwegian) is designed to give authorities, key decision-makers, and ordinary members of the public easier access to information about coastal and ocean areas.

Polar lows, also previously defined as polar mesoscale vortexes, Arctic hurricanes, Arctic lows, and cold air depressions, often have near-surface winds of at least 38mph (17m).

They are often of short-lived (about two days or so), but wind gusts can reach Beaufort 10 easily. Thunderstorms, water spouts, snow showers, and even blizzard conditions over are possible.

Termed as ‘near gale’ (Beaufort scale 7), pose a danger to oil activities, shipping, or other high-latitude activities. Conventional weather forecasts do not always pick these up.

Gunnar Noer at Norway’s Met Office explains the method is rather new with a degree of insecurity, as the development phase is not particularly old.

“What’s unique about this new method is that we run a model with ten different initial conditions, the former has only run a forecast that gave one solution,” he tells broadcaster NRK.
