Значение ледников, камение ледников и вечной мерзлоты в северной Тянь-Шань в условнякх повышения урвня воды по причине изменения климата
Trend analyses for the period from 1879 to 2000 at 16 climate stations located in and around Northern Tien Shan show an air temperature increase, which has become pronounced since the 1950s. This can be attributed mainly to a temperature rise in autumn and winter. However, the increase is less prono...
