I have a question about the following paragraph:


Ambient Temperature calculations are such that the average temperature at a given latitude will be similar to the same latitude in degrees north of the equator in a continental (ie non-coastal) location of North America. This results in world generation similar to that of the real world, with deserts near the equator, and arctic near the poles.

So if my z is currently -4602. I know I am north. How far north am I? Its 10,002 km from the equator in real life. So I'm 4.5 km from the equator.

(4.5/10,002)*90 = .0404 degrees north

Is this correct?

If so I'd like to add the example calculation to the page. I think it'll help clarify. –Preceding unsigned comment was added by Ratchet486 (Talk|Contribs) 22:35, September 22, 2014‎. Please sign your posts with ~~~~

The world in TFC isn't a 1:1 scale of earth. For reference, a z coordinate of 0 is the equator, while a z coordinate of -30,000 is about the equivalent of the arctic circle in TFC. That's only a difference of 30km in TFC, while in real life the difference is about 7,400km. So travelling 1km north in TFC can be roughly compared to travelling 250km on earth. So with some rounding, your original location of -4602 Z comes out to:
(4.5*250)/10,002*90 = 10.1230 degrees north. This coincides with the general idea of a Z coordinate of around -15k being a similar climate to the United States. --Kittychanley (talk) 05:39, 23 September 2014 (UTC)
That clears it up for me thank you. Do you think we should change the Coordinates page? --Ratchet486 (talk) 16:38, 23 September 2014 (UTC)
I've updated the section. Please let me know if there are any further changes you feel should be made. --Kittychanley (talk) 21:57, 28 September 2014 (UTC)
So at my Z coordinate of -8000 I am at about 17° north on Earth, so how come I am getting snow and below freezing from November to March? --Traisjames (talk) 12:40, 31 March 2015 (CDT)
TFC's climate system is based off of continental weather, i.e. weather that has no influence whatsoever from ocean currents. If you look on a globe for 17 degrees north, you'll notice that pretty much everything it goes through is heavily influenced by the ocean, so you really can't use the climate in those areas as reference. Also keep in mind that the weather fluctuates from year to year in TFC, so some winters are going to be colder than others. --Kittychanley (talk) 09:38, 2 April 2015 (CDT)
