View Full Version : Karnorthe

04-17-2009, 01:58 PM
I have been working for some years (sometimes seems like centuries) on my fantasy world of Karnorthe.

Recently I erased a continent from my world map and have been gradually remapping the rest of the world. However I need some help to determine ocean and wind currents on the revised world. I have assumed that the world is basically Earthlike, roughly same year, slightly higher temperature though. There are no land masses under the poles, and the dominant feature is the mountain range running east-west on the big central continent (heights around 18000 - 25000 feet) which I assume will have a major impact on climate in the area.

The attached hammer projection is basically just a sketch of the world as it now is. If any want to see the original it can be found at. Perhaps people could download the jpg, sketch the currents on it and reupload it to this thread?

I haven't got the foggiest idea about currents and climates so I'll just say that this looks good to me so far.

I've got an awful lot on my plate already, but here is an existing thread (by altasilvapuer) that might help you out some;


And then, of course, there is Geoff's Climate Cook Book, which might be of some help as well;

Some interesting stuff there. It will certainly help.

In the meantime, while trying to work out the ocean currents here is a picture of the world as seen from space. You can see how the main continent of Ethryn dominates the hemisphere.

And next to it is the continent as exported from Fractal Terrains into Campaign Cartographer 2 with some labels added. This was done some time ago and I have now come back to work on it, but I though some of you may like to see how it progresses from the start.

Here is my first attempt at showing principal ocean currents with the normal prevailing winds over the top (the short stumpy arrows) in addition some additions and alterations to the standard Fractal Terrains to CC2/3 output.

It seems like you've followed the default prevailing winds, with no allowance for differences between sea and land. Are you doing wind patterns later?

Not that I'm saying it's not alright, I've basically given up on climate making.

I will be doing the winds next. Over most of the planet "default winds" will probably be fine due to lack of land masses. Over Ethryn the big mountain range will block some of the westerlies. This range is nearly 26,000 feet in places (highest 25,975 ft). I picture this as producing cold air which will flow from the North East direction joining up with the North East Trades further south over the Sea of Shareale. This would give me a warm current flowing in the opposite direction to the prevailing cold air above. (Tornadoes?)

It looks to me like things are starting to come together rather nicely so far. Not being a CC2 user (or user of any version of CC for that matter) I'll refrain from comment on that part of things, but all in all, it's looking good to me.

Here is an enlargement of the region around the Kalsaar mountains showing what (I think) the mountain range would have on the prevailing winds in the region. The Westerlies striking the range are deflected north west and south east. Where they interact with the cooler easterlies rolling down the mountain slopes. To the north polar easterlies hitting the range are turned further east uniting with a westerly air flow over an ocean current rotating in the reverse direction. This would be slowed to some extent as a result of interaction with the air flowing in the opposite direction. (Of course this is just my opinion, what we need is an on-line climatolagist on this forum to sort out this sort of thing:))

Now onto mean surface temperatures. Attached is the temperature map as generated by FT. It can be seen that this has ignored potential ocean and air currents but has to some extent taken into account altitudes. On the map dark red is the hottest (approx. 100-110 F, cooling to around -10 to 0 F at the poles)

The next step will be to superimpose the ocean and air currents onto the temperature map and see where the currents take the temperatures.

Wow it has been a long time since I put anything here. Personally I blame a total computer failure and it taking a long time to rebuild everything. But now I'm back I will be doing more work on the world of Karnorthe.

In the extremely long time since my last post there have been major changes to the world. I even thought about changing the planet's name has to Arana which the attached map shows. I like this iteration better. The continents seem to fit together better too. Anyway here is a preliminary copy of the world as it now stands.

I very much like the shape of your continents. They're not blocky, like a lot of maps, and just have a nice feel about them.

02-10-2012, 03:09 AM
Here is the largest continent on the world, I decided to call the continent Arana and keep the world name as Karnorthe. The map also shows the central and eastern regions of the smaller western continent called Ethryn. It splits the oceans of the world in half, rather like North and South America so will have a wide variety of eco-systems present.

What about all the maps about climatics and oceanic currents you've done ... do they still apply? Those were astounding

02-10-2012, 12:40 PM
The currents will need to be modified since the continent size and placement has altered. The big continent will interfear with the ocean currents since it straddles so much of the world. So the results will be interesting. I'll have another go at these shortly.

looking forward to seeing those!

Here is the latest incarnation of my old continent of Ethryn. This is the one I basically cut from the old world and pasted into the new one where it looked more at home. On its new world it has basically been moved a little further north and is no longer the worlds dominant landmass.
