Abstract
We calculated the effective temperatures based on 10-year data for temperatures (monthly average and minimum), wind speeds (monthly average and maximum) and relative air humidity in the climatic zones of the Krasnoyarsk Territory (subarctic No. 1) and temperate continental (Krasnoyarsk (object No. 2) and Minusinsk (3) We assessed the health risk.In winter, in the subarctic zone, the temperature is –23.3 ± 1.5 0 C (minimum –30.2 ± 2.1 0 C), in object No. 2 — –17.3 ± 1.6 0 C (–19.3 ± 1.0 0 С) and object No. 3 — –19.9 ± 1.4 0 С (–25.5 ± 1.9 0 С). In spring at object No. 1 it varied from –16.5 ± 1.7 0 С to + 1.6 ± 1, 0 0 С, object No. 2 — from –3.9 ± 0.9 0 С to + 9.4 ± 0.5 0 С, object No. 3 — from –4.5 ± 0.9 to + 10.6 ± 0.4. Temperatures ranged from + 8.2 ± 0.9 0 C to –17.8 ± 1.2 0 C (object No. 1), from + 9.4 ± 0.5 0 C to –7.5 ± 0.9 0 C and from +10.4 ± 0.4 0 C to –6.4 ± 1.0 0 C. In summer, the temperature was 19.9 ± 0.9 0 C, 18.8 ± 0.3 0 C, and 19.8 ± 0.4 0 C, respectively. Wind speed at object No. 3.6 ± 0.05 m/s in July increased to 5.4 ± 0.2 m/s in December (maximum 16.2 m/s); No. 2 in July 1.4 ± 0.05 m/s, in October-May 1.8 ± 0.2–2.1 ± 0.07 (maximum in December 10.1 ± 0.1 m/s); No. 3 minimum wind in January and February (1.1 ± 0.1 m/s), maximum 10.7 ± 0.6 m/s in May. A moderately dry climate is recorded during 2, 4 and 5 months. In the conditions of Krasnoyarsk and Minusinsk in the spring, humidity drops to the limits of dry air. Average effective temperatures indicated a possible risk of frostbite in the subarctic zone after 20–30 minutes within 2 months; at minimum temperatures and maximum winds in March, frostbite in 20–30 minutes, in November, December and February in 10–25 minutes; in January — in 5 minutes. In the Krasnoyarsk region in January frostbite is possible within 20–30 minutes, in Minusinsk in February in 20–30 minutes, in January 10–15 minutes. Heat stress is undefined.
