On March 20, 2000, The Independent, a British newspaper, reported that “Snowfalls are just a thing of the past.” Global warming was simply making the UK too warm for heavy snowfalls. The column quotes Dr. David Viner of the Climatic Research Unit (CRU) of the University of East Anglia — yes, the epicenter of what would become the Climategate scandal — as saying that within a few years snowfall will become “a very rare and exciting event.” Indeed, Viner opined, “Children just aren’t going to know what snow is.”
Snow extent in the Northern Hemisphere at the end of November represents an important parameter for the early winter forecast. This year snow extent is running much higher than average and according to existing global estimates, it is now beyond the highest ever observed so far. Winter forecast, especially in its early phase and in Europe, might be strongly influenced by such a large snow extent, although many other factors need attention.
SNOW EXTENT IN NOVEMBER 2022
Northern Hemisphere snow extent is currently indeed very high, now at about 41 million square kilometers, according to the NOAA/Rutgers Global Snow Lab. The most recent snow cover information is given in the image below.
The Weekly Northern Hemisphere snow cover extent for the winter season 2022-2023 in purple is plotted together with the mean (grey dashed line), maximum (blue), and minimum (orange) snow cover extent for each week. Mean weekly snow cover extent and extremes were calculated using the 56-year period from October 1966 to July 2022.
Snow Extent in the Northern Hemisphere now Among the Highest in 56 years Increases the Likelihood of Cold Early Winter Forecast both in North America and Europe (severe-weather.eu)
