When touring, it is not enough to just pay attention to the maximum and minimum temperatures in the weather forecast! For comfortable touring, the temperature drop with altitude should also be considered. What is the relationship between altitude and temperature? Then we will explain
Relationship between altitude and temperature
It’s a quick answer.
By the way, let’s take a look at the altitude of each point introduced on this site.
| Location | Elevation | Estimated temperature drop |
|---|---|---|
| Gomasan sky tower | 1,300m | 7.8℃ Decrease |
| Aoyama Plateau | 700m | 4.2℃ Decrease |
| Odaigahara | 1,570m | 9.4℃ Decrease |
| Onyu Pass | 820m | 5.2℃ Decrease |
| Funaya house in Ine | 0m | 0.0℃ Decrease |
| Kumano Nachi Taisha Shrine | 330m | 2.0℃ Decrease |
In addition to the altitude, air currents from the mountains and ocean currents (cold and warm) affect the temperature, so it is not possible to generalize about the temperature. Motorcycles don’t carry a lot of weight, so it’s useful to wear thin but strong wind and cold weather clothing. A raincoat can also be used as emergency winter clothing.
At Mt.Fuji 5th Station, the temperature will drop considerably, so don’t forget to be prepared!
In the stratosphere, on the contrary, it seems to rise! ?
The stratosphere ranges from 12 to 50 km altitude. It seems that the temperature is almost constant at -56.5°C up to an altitude of 12 to 20 km. The reason is that the ozone layer absorbs ultraviolet rays from the sun and converts them into heat energy. I can’t climb to that altitude on a motorcycle, but as a diligent knowledge.
Summary
In addition, as the speed increases, the temperature that the body feels (feeling temperature) also decreases. I would like to make another article on this.
It is important to never go out touring in light clothing just based on the weather forecast temperature.
This is also effective for keeping your hands warm.
