It´s already the second time during Winter 2021/2022, when Ain Sefra, Sahara, Algeria reports snowfall /https://mkweather.com/collapse-of-atmospheric-circulation-snowing-in-ain-sefra-sahara-algeria//.
According to measurements, snowing in the region is statistically rare, but in the last years is occurring anomalously often.
Snowing in Ain Sefra is dated in the years 1979, 2016, 2018, 2021, and 2022.
4 from 5 years in history with snowfall in Sahara, therefore, appeared in the last 6 years.
This surprising effect should be contributed to climate change associated with changes of jet-stream configurations during winters, especially their amplitude and frequency during AO- and NAO- phases.
It appears, that Rossby waves are more and more prolonged from north to the south, with effects of more frequent snowing in anomalously southward areas.
It´s possible, that similar snowfall in parts of the Sahara will occur despite warming trends in the following decades, too, and even, snow should appear in totally new localities, more southward or lower elevated.
