Details

The current default world generation settings are a maximal map height of 30 and a snow line height of 15, while tropical tree line height is calculated automatically based on the maximal map height and can not be set, afaik.
In effect in sub-arctic there is no snow and in sub-tropic there are no tropical trees except at the coast-line, when using the default settings.

For sub-arctic setting the snow line height to 5 provides sufficient snow and
for sub-tropic setting the maximal map height to the historic value 15 gives tropical forests.
This task depends upon

In r27334, changes to the terrain generator were reverted.
Does that fix your problem?

I tested the current trunk r27346 and the issue was still there. I think this is not related to the noise generation, but only to the height limits.

Confirmed, if I remove openttd.cfg and start OpenTTD 1.7.1, using default world gen settings
- no snow in sub-arctic
- no trees in sub-tropic
