Аннотация: A correlation analysis of long-term dynamics of sea ice area in the Northern hemisphere with high spatial resolution insolation characteristics was performed. For the period from 1901 to 2018, close negative relationships between long-term changes in the sea ice area, winter insolation and insolation contrast were found in 1° x 1° cells. Maps of distribution of closeness of connection of long-term changes in sea ice area with insolation characteristics for average annual, semi-annual and monthly (March, September) values of sea ice area are constructed. It is shown that the relationship of long-term changes in the distribution of sea ice in the Northern hemisphere with insolation contrast is causal and insolation contrast can be a predictor in statistical models of sea ice dynamics. It is determined that the Northern Sea Route is characterized by close connections of sea ice distribution with insolation contrast throughout its entire length. This creates prospects for long-term forecasting of the sea ice area for the Northern Sea Route based on calculations of insolation contrast for the Northern hemisphere.
