Comme \u00e0 la fin de l\u2019ann\u00e9e 1996 d\u00e9but 1997, nous avons connu un \u00e9pisode froid, presqu\u2019aussi qu\u2019\u00e0 cette \u00e9poque. En effet entre 1997 et 2008, nous n\u2019avions plus connu \u00e0 Uccle de journ\u00e9e tr\u00e8s froide (temp\u00e9rature minimale inf\u00e9rieure \u00e0 -10\u00b0C).<\/span><\/p>\n

Chaque \u00e9pisode froid (ou chaud) a ses propres caract\u00e9ristiques. On peut cependant comparer diff\u00e9rents param\u00e8tres qui peuvent les caract\u00e9riser. C\u2019est ce que l\u2019on trouve dans le tableau suivant :<\/span><\/p>\n

L\u2019examen du tableau montre clairement que la vague de froid de 96-97 fut plus s\u00e9v\u00e8re que la vague de froid que nous venons de conna\u00eetre.<\/span><\/p>\n

Du cot\u00e9 enneigement, la neige s\u2019\u00e9tait maintenue du 31 d\u00e9cembre 1996 au 10 janvier 1997 (11 jours) et l\u2019\u00e9paisseur maximale de la couche de neige avait \u00e9t\u00e9 de 3 cm. Cette ann\u00e9e, la neige a atteint 8 cm et s\u2019est maintenue 8 jours au sol (du 5 au 12 janvier 2009).<\/span><\/p>\n

C\u2019est l\u2019hiver 1962-1963 qui reste le plus froid de tous les hivers observ\u00e9s \u00e0 Bruxelles-Uccle depuis 1834. La temp\u00e9rature moyenne pour les 3 mois de cette saison a \u00e9t\u00e9 de -2,0\u00b0C et les temp\u00e9ratures n\u00e9gatives ont \u00e9t\u00e9 observ\u00e9es pendant 74 jours sur les 90 que compte l\u2019hiver.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
