Description :
The aim of this paper is to attempt a first understanding of the synoptic weather conditions associated with soil frost occurrence on Marion Island. Specifically, the AA. hypothesise that soil frost is dominant under specific air circulation patterns and is associated with clear skies. The study was conducted in the interior of Marion Island at Katedraalkrans in the polar desert habitat : scoria and black lava deposits almost completely unvegetated. Therefore this site allows for a direct exchange between atmospheric conditions and ground temperatures. Results and discussion.
