Climate change effects on winter river runoff in Transbaikalia

Abstract

Considered are interannual variations of the river runoff in Transbaikalia during the freeze-up and their dependence on the climate change. The air temperature in winter has increased since the middle of the 20th century that results in the ice thickness decrease on the majority of rivers on the territory under study. The runoff volume in winter depends significantly on the preliminary moistening of catchments. Warming effect is manifested in the increase in the fraction of the winter runoff in the annual runoff volume during the long-term period.

Contrasting Changes in Vegetation Growth due to Different Climate Forcings over the Last Three Decades in the Selenga-Baikal Basin

“…The change trends in air temperature exhibited different patterns among seasons as shown in Figure 4, and a significant increasing trend can be observed in spring and summer. The winter temperature, in contrast, decreased during the 1982-2015 period, which is consistent with recent studies, e.g., [23,64,65]. However, the decreasing winter temperature trend in the Selenga-Baikal Basin did not pass a significance test at the 0.05 level.…”

Гидрохимическая И Микробиологическая Характеристика Соленых Озер Шихалин-Нур И Хара-Нур (Юго-Восточное Забайкалье)

“…Соленые озера представляют собой уникальные объекты для широких научных исследований [Заварзин и др., 1999; Солоноватые и соленые... 2009; Hardie еt al., 1978]. Постоянный интерес к изучению этих экосистем связан, во-первых, с эволюционными процессами развития геобиосистем [Obyazov, 1996]; во-вторых, рациональным использованием их биологических ресурсов [Бархутова и др., 2018]; в-третьих, они являются источниками уникальных микроорганизмов с большим биотехнологическим потенциалом [Nerbert, 1992].…”
