A small correction, the image you have of the US West Coast is primarily defined by the Cascade and Sierra Nevada mountain ranges, with the Rockies not starting until further east. I think you fully achieved your goal of a clear and concise breakdown of the rain shadow effects globally!

Ah yes, for us non-US-natives it's all the Rockies!

In many places, the phenomenon you describe is well-known to hikers and can be visible immediately once you hike certain altitude. Crossing the ridge, you suddenly move from a forest directly to a desert. This can be observed in many Atlantic islands, like Madeira, Tenerife or Cape Verde's Santo Antao of which I have been writing lately.

Lovely article. The Weathermakers project is a fascinating example of geoengineering based on the same phenomenon - using silt from Lake Bardawil to regreen the landscape north of Mount Sinai and its surrounding range. It's really worth a look on YouTube.

Just looked one of their videos. How are they supposed to get the water? That's what's missing there. What change is supposed to bring water there that today isn't raining down?

They have domes that they are filling with plants which desalinify the water - they've done some tests already..

Been thinking about this all evening. Thx!

I love your articles - I think we have similar perspectives, and I found this whole project fascinating - the Loess plateau restoration is so inspiring by itself. I really hope the Sinai project moves forward - it could mean so much to Egypt, as well as providing inspiration to the rest of the world!

I'm at the airport and have just learned my flight is 4 hours delayed, which meant I had the time to pause my complaining and read this post to then marvel at how beautiful and intricate nature is.

I can now resume my complaining.

You should rename this article "Maps without New Zealand"

It has its own rain shadow effect, but the dry part doesn’t look like a desert to me…

It’s pretty desert like in the south! Not quite sand dunes, but a huge difference in rainfall between west and east coasts.

It's very clear and interesting explanation of the geographical efects on the land we live in. Almost all is about that parameter in conjuction with geological and antrophic ones. Kind regards, Modesto.

Great article. You cannot understand human history without a foundation in geography.

Geography enables agriculture.

Agriculture enables civilization.

That’s a short one: “You gotta be crazy to have read all my content, hence short of a good and accessible index on the content, I’m the index”

Great article! Is the Arabian Peninsula an anomaly on the Wet/Dry (next to each other) map? No proper wet areas anywhere on the peninsula or rivers.

It’s the same as the others, except it has a much drier baseline, so both sides appear dry (even if one is livable and the other is a desert).

Why so dry? Arabia has the same geography as the Sahara. The only reason why its coast has some population I because it gets rains from the Red Sea’s humidity.
