Water and ice regime of the Pechora River mouth under current hydroclimatic conditions

The article presents the features of the water and ice regime of the Pechora River at its mouth for the entire observation period and in modern climatic conditions. The temporal variability of the main characteristics of the water and ice regime of the river (in its lower reaches and at its mouth) and the climatic conditions of its formation are analyzed, including data from the hydrometeorological network in the river basin. The initial data were the materials of stationary observations at hydrological gages and meteorological stations up to 2021/2022. It is shown that against the background of a noticeable increase in surface air temperature and precipitation amounts from the late 1980s – the early 1990s (the first) and from the early 2000s (the second, most pronounced), an increase in water discharge was noted in all phases of the water regime with an insignificant redistribution of runoff in favor of the low-water seasons. The duration of the period with ice phenomena decreases, and the conditions for the passage of spring ice drift and the formation of higher water levels change.
