Summary: | Influence of the Kongsfjord on maximum temperatures near the French camp (Ny Aalesund Svalbard). The temperature variation is studied between Ausire and Midre Lovenbreen (glaciers) and the shore Kongsfjord Spitsbergen. The situation has been observed in different weather situations (fine bad and intermediate weather) and under different winds (northerly and southerly). The influence of the fjord on the temperatures on the strandflat is especially studied. It may be seen that it is strongest with northerly winds and smallest with southerly winds. The direction of the wind is thus the main factor to explain the air advection to the strandflat. However the topography and the microenvironments are also to be considered : they make easier or counteract the air flow from the fjord to the southern parts of the strandflat. Cet article propose l'étude de la variation de la température (observée à 1,5 m au-dessus du sol avec des thermomètres à maxi/mini) entre l'Austre et le Midre Lovenbreen et la côte. La situation est observée avec plusieurs types d'ambiances climatiques (beau temps temps médiocre et mauvais temps) et avec des vents originaires du nord et du sud. L'influence du fjord sur les températures du strandflat est tout particulièrement étudiée : on peut constater qu'elle est maximale par vent de N. et minimale par vent de S. Mais la topographie et les micromilieux interviennent aussi en contrariant ou facilitant l'invasion de l'air du fjord vers le sud. |
