The practical analysis of the growth of a sea-ice cover is discussed with initial reference to the classical work of Stefan, whose basic equation connecting surface temperature with the growth of a uniform ice cover of negligible specific heat and hence infinite diffusivity is extended to cover “real” cases. The separate effects of a finite heat content and thermal diffusivity are derived theoretically and semi-empirically respectively, and combined in a more general ice-growth equation which is then tested in the analysis of annual sea-ice growth on Hudson Bay.
L’analyse pratique de la croissance d’une couche de glace de mer est discutée. L’équation classique de Stefan qui donne la croissance en fonction de la température de la surface d’une couche de glace de chaleur spécifique négligeable et, par conséquent, de diffusivité thermique infinie, est modifiée pour couvrir les cas pratiques. Les influences de la chaleur spécifique sont déduites théoriquement et celles de la diffusivité thermale d’une façon semi-empirique. Elles sont enfin combinées dans une equation plus généralisee, qui est ensuite vérifiée dans l’étude de la croissance de la glace de mer annelle faite a la baie de Hudson.
Die praktische Untersuchung des Wachstums einer Meer-Eisdecke wird unter anfänglichem Bezug auf die klassische Arbeit Stefan’s besprochen, dessen Grundgleichung den Zusammenhang zwischen Oberflächentemperatur und Eisbildung im Fall vernachlässigbarer spezifischer Wärme und daher unendlicher Wärmediffusion darstellt. Der Anwendungsbereich dieser Gleichung wird auf“wirkliche” Fälle erweitert. Die Einflüsse einer endlichen spezifischen Wärme und Wärmediffusion werden getrennt theoretisch beziehungsweise halb-empirisch hergeleitet und dann zu einer allgemeinen Eisbildungsgleichung verbunden, die durch eine Untersuchung des Wachstums jährlichen Meer-Eises in der Hudson Bay geprüft wird.
