It is not every day that you can write that \u00a0good news comes from Siberia\u00a0. But that’s how it is: the world is warming at an \u00a0unprecedented rate\u00a0, Arctic ice has reached historic lows in 2025, and the temperature of the Arctic Circle is increasing up to \u00a0four times faster\u00a0 than that of the rest of the planet.<\/p>\n
<\/p>\n
And yet, snow coverage in Siberia has reached an \u00a0above-average extent\u00a0.<\/p>\n
But the important thing is not that. The important thing is not the \u00a015.59 million square kilometers\u00a0 of snow in the northern hemisphere, nor what they mean for the region’s weakened ecosystems. The important thing is that, whether we want it or not, it can be \u00a0sensational news\u00a0 for Spain.<\/p>\n
<\/p>\n
At the end of the 90s, Judah Cohen<\/a>, an MIT climatologist, began to notice the blanket of snow that covered Siberia before November. Almost by chance, he discovered that its size kept a very close statistical relationship<\/a> with climatic patterns occurring in the rest of the continent.<\/p>\n <\/p>\n Initially, the international community viewed his findings with \u00a0suspicion\u00a0. However, after \u00a020 years\u00a0 of research, the \u00a0Siberian Snow Advance Index (SAI)\u00a0 has become well-established. Yes, indeed: what happens in Siberia has a lot to do with what happens here in Spain.<\/p>\n <\/p>\n The \u00a0mechanism\u00a0 is incredibly simple, yet its implications are enormous. The abundant snow cover in Siberia influences weather patterns across Europe through a \u00a0feedback loop\u00a0. “More snow” equals “more albedo,” which leads to more solar reflection, colder soil, and, consequently, a \u00a0‘push’ to the Siberian anticyclone\u00a0. The stronger that anticyclone becomes, the more upward flow into the stratosphere occurs, leading to more sudden warmings and more \u00a0tropospheric patterns of negative Arctic Oscillation (AO)\u00a0. In summary, \u00a0more air masses move\u00a0 towards mid-latitudes, resulting in more storm systems aimed at our geography.<\/p>\n <\/p>\nHow is it Possible?<\/h2>\n
