A mixed start to the year<\/strong><\/h3>\n

The year 2023 starts with new temperature records. The lack of snow is felt above 2000 meters leaving the ski resorts without snow. The reason ? Mild air masses from the west and southwest resulted in exceptionally high temperatures, especially in the Alps. According to MeteoSwiss, average daily temperatures for the first two days of January exceeded the 1991-2020 norm by 10 to 13\u00b0C in some regions. In Del\u00e9mont, in the canton of Jura, the mercury reached more than 20\u00b0C \u2013 the highest temperature ever recorded for a January day ! We can then observe the flowering of hazelnut trees instead of sliding down the ski slopes. However, from January 16th the trend reverses and the green Alpine meadows and slushy ski slopes leaving a magnificent winter landscape. Experts are predicting more than 70 cm of fresh snow above 1’600 metres in the Swiss Alps. Indeed, a polar air coming from the North Atlantic is flowing towards central Europe bringing snow up to low altitude. In the second half of January, polar temperatures between -20 and -25\u00b0C can be observed in some regions of the Alps and the Jura. The animated image is derived from two satellites images captured with the Sentinel-2 satellites available on the Swiss Data Cube (SDC) platform. It shows the difference in snow cover between the first (4.01.2023) and the second half (24.01.2023) of January 2023 in two ski resorts, Villars and les Diablerets, located in the Alps. In the first image, we can see the ski slopes covered with artificial snow in the middle of snow-free meadows (white band in the middle of the first image). Monitoring snow cover is of crucial importance for many issues such as climate change and is on the SDC mission.<\/p>\n

\"\"<\/p>\n[fr] Un d\u00e9but d\u2019ann\u00e9e \u00e0 demi-teinte – <\/strong>L\u2019ann\u00e9e 2023 commence avec de nouveaux records de temp\u00e9rature. Le manque de neige se fait sentir en dessus de 2000 m\u00e8tres laissant les stations de ski sans neige. Le responsable ?  Des masses d\u2019air doux provenant de l\u2019ouest et du sud-ouest entrainant des temp\u00e9ratures exceptionnellement hautes, notamment dans les Alpes. Selon M\u00e9t\u00e9oSuisse, les temp\u00e9ratures moyennes journali\u00e8res des deux premiers jours de l\u2019ann\u00e9e ont d\u00e9pass\u00e9 la norme 1991-2020 de 10 \u00e0 13\u00b0C dans certaines r\u00e9gions. A Del\u00e9mont, dans le canton du Jura, le mercure atteint plus de 20\u00b0C, un record pour un jour de Janvier! Nous pouvons alors profiter des noisetiers en fleurs plut\u00f4t que de d\u00e9valer les pentes de ski. Apr\u00e8s cette longue p\u00e9riode sans chute de neige, la neige arrive dans le 2\u00e8me quart de janvier laissant place \u00e0 un magnifique paysage hivernal. Les experts annoncent plus de 70 cm de neige fraiche au-dessus de 1600 m\u00e8tres. En effet, un air polaire provenant de l\u2019Atlantique Nord s\u2019\u00e9coule vers l\u2019Europe centrale amenant de la neige jusqu\u2019en basse altitude. On observe alors des temp\u00e9ratures polaires oscillant entre -20 et -25\u00b0C dans certaines r\u00e9gions des Alpes et du Jura. Cette image anim\u00e9e est issue de deux images satellitaires provenant de Sentinel-2 disponible sur la plateforme du Swiss Data Cube (SDC). Elle montre la diff\u00e9rence de couverture neigeuse entre la premi\u00e8re et la deuxi\u00e8me moiti\u00e9 du mois de Janvier dans la r\u00e9gion de Villars et des Diablerets. Dans la premi\u00e8re image, nous pouvons observer les pistes de ski recouvertes de neige artificielle au milieu de prairies sans neige (bande blanche au milieu de la premi\u00e8re image). La surveillance de la couverture neigeuse est d’une importance cruciale pour de nombreux domaines tels que le changement climatique et fait partie d\u2019une des missions du SDC.<\/p>\n","protected":false},"excerpt":{"rendered":"
