The Caravel Mod

[gollum]

Regarding the weather:
Snowfall seems most likely linked to precipitation values in the file, and so there is considerable chance for snowfalling on snowy terrain now, as precipitation is increased. The terrain with higher chance for snow is Temperate and the presence of it abounds in the map of the Caravel mod, so players of teh Caravel mod will get more snow and snowfalls in their battles.

If you like the weather modification, you can also use the modified WEATHER file in your own modifications or in other modifications for MTW/VI v2.01. It should work, and you get the benefit of that in the mod of your choice or in vanilla.
