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 July
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.

  1. Wow! You are really detailed about Arnâron. Good luck in Worldbuilding Month

    Oh and thanks for the comment.


  2. Thanks – Not as detailed as I could be – but then Geogrpahy class was 16 years ago, and I have a day job now, so I have to find a compromise between time invested in my world and sleep I get every night. 🙂

  3. I must know how you did this! I’ve been aiming to do wind pattern direction mapping for Doth and my other worlds for some time—and I’ve always wondered, how exactly do you place high pressure and low pressure regions?

  4. Oh, and PS – I found it really, really helpful to look at maps of Earth which depict wind patterns and ocean currents.
