Abstract
Because of significant physical differences between snow and other naturally occurring substances, snow is not only a valuable resource but it also has significant large-scale effects on weather, climate and the hydrological cycle. A working group of the IAHS International Commission on Snow and Ice (ICSI) has recently reached certain conclusions regarding these effects. In order to study and model the large-scale effects of snow, the standardization of existing ground observation methods, the exploitation of new technologies such as remote sensing, and the systematic archiving of all data are necessary. Various research efforts and international activities have been identified which, when accomplished, should lead to improved understanding and management of the large-scale effects of seasonal snow cover. An international organization should take the lead in promoting an exchange of ideas, techniques, measurements, research results and management strategies on large-scale snow studies.
