Territorial zoning for the purpose of reforestation from changes of total ozone content in the atmosphere (exemplified by the Tomsk region)

Based on analyzing and forecasting the reconstructed changes of total ozone content (TOC) in the atmosphere over the Tomsk region, two zones of its changes are identified. It is shown how the capacity for survival of conifer transplant stock can be enhanced on the basis of territorial zoning from TOC changes by varying the time and place of planting.

Numerical solution of the equations for spatial nonlinear steady-state traveling waves on the free surfaces of homogeneous and two-layer bodies of water

This study is devoted to the construction of some numerical solutions to the previously proposed model equations for three-dimensional disturbances of a small but finite amplitude in liquids of a constant depth. The forms of progressive steady-state waves (both periodic in two horizontal coordinates and solitary) are demonstrated. In a homogeneous liquid, these forms depend on the magnitudes and directions of the wave vectors, whereas, in bodies of water with a small density jump, they also depend on the ratio of layer depths.
