Changes in Lake Ice Cover on the Morskie Oko Lake in Poland(1971-2007)

引用

Advances in Climate Change Research 2010年第2期1卷 71-75页

作者： Adam Choiński leszek kolendowicz Joanna Pociask-Karteczka leszek Sobkowiak Institute of Physical Geography and Environmental Planning Institute of Geography and Spatial Management

On the basis of data from the period 1971-2007, and by applying trend analysis, a study on formation, disappearance and duration of lake ice cover on the Morskie Oko Lake in the Tatra Mountains in southern Poland was carried out. The results show decreasing trends in the maximum thickness of winter lake ice cover and in duration of lake ice phenomena, while air temperature recorded at the same period at the foot of the Tatra Mountains shows increasing trend. There are strong relationships between the course of lake ice phenomena and air temperature.

关键词： lake ice cover thickness duration of lake ice phenomena air temperature
