Climate condition of Chernobyl Exclusion zone

Chernobyl zone climatic conditions are rather good studied. Around chernobyl’s territories are 3 meteorological stations (Chernobyl, Polisske, Bragin) in radius of 50 km. On the distance 70 – 110 km situated meteorological stations Teterev, Ovruch, Oster, Chernigov. It takes a rather long period to make observation per all the stations. To make description of the region climatic conditions, the data of the nearest meteorological station placed in Chernobyl town.

Soil character of Chernobyl zone

Lithologic structure of the most widely distributed type soil on Exclusion zone:
Top layer of soil, named us “Soil-vegetable layer” have a thickness 0.2 – 5 m and presented by loam sand and loams, containing a majority of the plants roots. On the picture you can see the view of Chernobyl’s soddy-podzolic soils (0-100 sm layer).
Next layer – “Soils of flood-plain phase” presented by the powder sands, fine and middle size sand, loamy sand and rarely by loamy soil.
Soils are characterized by the heterogeneous settling. Thickness of flood-plain sediments varies within the limits of 5 to 7 m.
