With a country as big as Russia, it is hard to give you an accurate estimation. Siberia is known for some of the coldest winters in the world, reaching a very dangerous -35 degrees Celsius. The north pole of cold has a record breaking -69 degree celsius winters. over 65% of Russia is covered by permafrost. There is a humid continental climate as well.
I don't know exactly which three but these could be some...
Studying local native traditions and life ways in order to become familiar with the local region
Local ecology
Observation: reading the landscape
Animals: tracking, hunting, trapping, making bow and arrows, animal food preparation
Identifying, harvesting and preparing wild edible plants
Fire making
Tool Making and flint knapping
Creating fishing equipment (hooks, lines, etc.), fishing, gutting and preparing fish for cooking
Shelter: building using local materials found at the site
The waste stream: where to excrete
Invisible structures: tribal culture and local tribal custom
Hope this helped!
In most cases, as altitude increases, the air in the troposphere cools. Vertical mixing occurs as a result of warm air rising. However, a layer of cool air may form beneath a layer of warm air on occasion. Temperature/thermal inversion refers to this deviation from normal temperature.
When an inversion occurs, polluted areas (such as London and Donora PA) experience unhealthy air and an increase in smog because pollutants are trapped at ground level rather than circulating away.
If it's asking a combination of culture traits in a culture group then the answer is culture complex.
