The soil is sub-freezing nearly half of the year, but does warm with longer-days. So, you are right that it still gets relatively 'hot'. Tibetan soil and moisture study PDF | |

The atmosphere as a whole is not lifting from sea level, so I should've referenced the environmental lapse rate of 6.5°C/1000m instead of dry adiabatic lapse rate of 9,8°C/1000m..

There are too many sources of heat loss surrounding any point that attempted to warm. In any direction above the surface, there would be cold, dry air sapping heat from said surface. In any direction to the sides or below an insolated surface, you would have colder earth also sapping any heat. Any kind of wind would only further accelerate the heat drain. | |
