Modeling of the influence of local climatic features on the functionality of the cryolithozone road network in the conditions of global warming
The road network of the cryolithozone of Russia, operated in conditions of ongoing climate change. To quantify the expected negative consequences of the degradation of permafrost soils at the base of the road network, taking into account the local climatic characteristics of Yakutsk, Susuman and Ure...

The road network of the cryolithozone of Russia, operated in conditions of ongoing climate change. To quantify the expected negative consequences of the degradation of permafrost soils at the base of the road network, taking into account the local climatic characteristics of Yakutsk, Susuman and Urengoy. Simulation modeling of the processes of propagation in the soil of the road profile of thermal energy delivered jointly by both ambient air (convective heat exchange) and solar radiation in the surface layer (radiation heating). The magnitude of climate risks is estimated on the basis of soil precipitation at the base of the road network caused by additional thawing under the influence of global warming. New data on the state of the road network as the most important element of the regional road transport system in the conditions of climate change have been obtained.The predicted value of additional soil precipitation at the base of roads with warming up to 2 degrees, determined without taking into account the incoming solar radiation into the ground, is: for dry sandy soils 0.7-0.9 cm, for wet clay soils 2.2-2.6 cm.
