Reply to comment by jaceapoc in Mean annual temperature in Trentino-Alto Adige (1981-2016) [OC] by has14952

Basically at each point the temperature values are averaged across the time specified time period (1981-2016) and the magnitude of said average value is represented by a color (color bar on the right shows the general range each color represents).

Trentino is the region home to the Dolomites so it has both valleys and mountains. As one would expect, the valleys are the parts of the region with higher average temperatures and the mountains will have lower temperatures due to their elevation. So using just a temperature map, you get a pretty good idea of the overall topography of the region as well.

I mean, but this is then basically just elevation map. But made indirectly through temperature. Because there is a direct correlation of temperature with elevation, where for every 1000m temperature is lower by 6.5C (in average).

Effectively yes. But given that it just shows us the general patterns of elevations i.e. the locations of mountains and valleys rather than their actual specific height above sea level, I feel it would be wrong to classify it purely as an elevation map.

So it is a fuzzy elevation map. :)

You might use this to expand it to gain new information though. Create three maps:

  • pure elevation
  • pure mean temperature for that time period (this one)
  • and offset between yearly temperature at certain altitude and these data. You can do it one year average vs this average. Is it getting warmer in valleys? Is it warmer than expected higher up?

Wdyt?

ooooh very interesting idea. definitely worth checking out for sure

Thanks. I thought I was supposed to read it as a line graph and was looking for a 1981-2016 time axis, and also that you used the valleys as some sort of design for a line graph...

I think I got confused by the coordinates and the "square".
