Abstract
Correlations between the amount of precipitation in the Lena and Yana river basins in winter and the ice coverage of the Laptev and East Siberian seas near the New Siberian Islands in the spring-summer period are studied based on the GLORYS12v.1 and ERA5 global reanalyses and archival meteorological data. A statistically significant correlation (with a confidence level of at least 0.95) was established in the certain parts of the study area. The Yana basin winter precipitation was found to have the highest correlation with the ice coverage in May. The correlation between the Lena basin precipitation and the ice coverage in July is lower, but also significant. During the other months, no significant correlations were revealed. The established facts may be of practical use for long-range forecasting of ice conditions near the New Siberian Islands at the beginning of the summer navigation along the Northern Sea Route.
