The location of the arctic front and its possible change on the territory of Russia was investigated using various meteorological parameters during the winter and summer seasons at the end of 20th – beginning of 21st century and using climate projection according to the regional climate model of Main Geophysical Observatory scenario. Warming was observed in the north of Russia at the end of 20th – beginning of 21st century. Location of the branches of the arctic front was quasi-steady in the same period. According to scenario of the regional model, it is expected that the situation will not change until 2060. The increase in temperatures in winter and summer will continue. It is possible to expect the multidirectional changes of the largest surface air temperature gradients as the characteristic of the arctic front. The values of gradients can be reduced on the territory during the winter season in the first half of 21st century. Increasing of the temperature gradient will be observed at the area of the main branch of the Arctic front in the summer. This can affect the structure of vegetation cover in the subarctic zone in the north of Russia.
