Influence of Air Temperature on the River Runoff in Winter (the Aldan River Catchment Case Study)

摘要

Influence of air temperature and ice cover thickness on the Aldan catchment rivers runoff in the wintertime is analysed. It was revealed, that decrease in the river ice cover thickness in warm winters leads to increasing discharge capacity of river channels, which causes increasing river runoff. A regional relationship which describes correlation between the runoff depletion rate and the air temperature sums in the first half of winter and the ice cover accumulation intensity was obtained.
