Mapping Arnâron – Wind Patterns

Okay, this one was a tough one, and I am not sure how realistic the result is. Nils presents: The prevailing winds of Arnâron! Red circles are high pressure areas, blue circles are low pressure ares; the thin black arrows are prevailing winds. The thick black line is the intertropical convergence zone.

These maps are based on the general idea that the north is colder during the “beginning of the year”, aka “January”, while the south is warmed in the “middle of the year” aka “July”. I also used the ocean currents as a basis of where to place high / low pressure areas.

Arnâron - Winds in January

The ITCZ should probably extend far to the north in the middle of the year (lower map).

Looks confusing? Yes, to me too. But it’s giving me some ideas for climate zones already; for example I think the eastern half of the south-eastern landmass may be a desert, as its coastal mountain ranges will likely shield it from rain in the “beginning of the year” phase (“January”), and the wind will go the other way in the “July” phase. The southern half of the western continent is probably desert, too.

It is also worthy to note that seasonal changes will in general be more gentle than on Earth, because the year is much longer.

Laying down climate zones is the next logical step, too. Once I am done with that, I’ll be able to determine where people originated, where civilizations rose, and where humans stagnated. This is also where we join the Shakespeare & Dragons podcast again.

Mapping Arnâron, Ocean Currents

More maps = good. This time: Stirring up the oceans!

Arnâron - Ocean Currents

I should probably note that oceans on Arnâron were never as deep as on Earth. I figure maybe a kilometer or so at the deepest.

Wind patterns should be fairly easy and somewhat less static than ocean currents. Nevertheless, I’ll put wind patterns off until tonight or so, and then I’ll finally be able to determine what location will have what climate.

And you know what’s the kicker? This is still ancient Arnâron. Soon, the oceans will dry up, the wind will change, and climate will be radically different. I’m creating this water-rich, pleasant garden world just to destroy it.
