Winter streamflow, ground temperature and active‐layer thickness in Northeast China
Abstract Seasonal freezing and thawing influence the hydrological regimes of winter streamflow in northeast China where abrupt increases of 1.3° C and 2.8° C in the annual and winter air temperatures have occurred since the 1990s. Correlation between winter discharge and soil freezing is based upon...
