Hi,
thanks, yes, it is very interesting.
Koppen is the traditional system used most often, unfortunately, it was developed at the beginning of last century and is no longer very accurate. For example, it shows "subtropical climate" for the city where I live, even though we are definitely in the "temperate zone". The Trewartha classification is a newer system, which is build on Koppen, but adjusts the values to better reflect reality. It is also more difficult to calculate, but you do not have to worry about that because it is calculated by the script.
I made this plugin while I was preparing for my PhD exam from climatology which was yesterday
One of the topics on the exam was climate classification and by doing this plugin I memorized it all :-)
The only problem for some of you could be the language... this is one of those plugins that has too much text to be easily translated using the system used by Meteotemplate, but hopefully people will understand it, at least the calculators should be easy to understand and use even without knowing English.
And to compensate for that I created that block for you which has forecast in Spanish
That was actually quite difficult for me to make because I did not understand it... but hopefully it was worth it and it seems to be working fine :-)
Enjoy
