Under the Wikipedia article Temperate climate Temperate climate in the introduction is describes:
In geography, the temperate or tepid climates of Earth occur in the middle latitudes, which span between the tropics and the polar regions of Earth.
So by this sentence I take the temperate zone to be between the pink shaded area (the tropics, and the uppermost and lowermost broken lines (arctic and antarctic circles. This is simple enough.
Then in the next paragraph it says:
The temperate zones (latitudes from 35° to the polar circles at about 66.5°, north and south) are where the widest seasonal changes occur, with most climates found in it having somewhat balanced influence from both the tropics and the poles.
Now it says that the temperate zones are between latitudes about 35 degrees from the equator to the polar circles. This is different than the earlier description, which said it was between the tropics and the polar circles, which is about +- 23.5 degrees to the polar circles, not 35 degrees.
A little lower it says:
The north temperate zone extends from (approximately 23.5° north) to the Arctic Circle (approximately 66.5° north latitude). The south temperate zone extends from (approximately 23.5° south) to the Antarctic Circle (at approximately 66.5° south).
Zones and climates
So now it's saying again the temperate zone is between the tropics (23.5 degrees latitude) to the polar circles.
Lower again it specifies that there is a suptropical zone, namely:
Subtropical climates are generally located between 23.5° and 35° north or south on the eastern or leeward sides of landmasses. Humid subtropical climates
It's now specifying zones of the subtropics, but it doesn't change the fact that in the first instance it says the the temperate zone is between the tropics, +/- 23.5 degrees, and the polar circles, and then says the temperate zone is between 35 degrees to the polar circles, a definition which excludes the subtropics from the temperate zone.
Which one is correct? Is there a contradiction here? If so, is it a mistake or something more subtle I don't understand?
