  1. ​ @casualearth-dandavis best of luck to you!

  3. I would also recommend Geodiode.

  4. Does the fact that the Indian ocean is landlocked also cause aridity in Arabia? As there's no northern high-pressure area and therefore no warm currents or onshore winds that would bring rain to the Arabian peninsula and North Africa as is the case in the southern United States or southern China, hence no Humid Subtropical climates in these parts as is the case in similar latitudes elsewhere.

  5. Mombasa has a Savanna climate as opposed to an arid one.

  7. Does this also apply to islands in SE Indonesia that are affected by the cold West Australian Current?

  9. That's so cool to think about

  10. My takeaway from this: Arabia north of the Tropic of Cancer is within the normal latitude of atmospheric subsidence within the Hadley Cell, but southern Arabia, at a latitude of 12° north, is within the normal latitude of Tropical Savanna climates and is a desert for entirely different reasons, and would have had a monsoon were it not for India.

  11. Can't wait for the video on east African deserts

  12.  @serenissimarespublicavenet3945  Yes, I was referring to Liguria in my question. My bad.

  13.  @skp8748  Mount Kilimanjaro, Somali Plateau..

  14. ​ @ForageGardener the eastern US too certainly is rain-shadowed too.

  15. Same!

  16.  @casualearth-dandavis  Oh my, I'm truly looking forward for most of those

  18.  @casualearth-dandavis  but wouldn't that mean they'd have to pass over Tanzania first? Northern Tanzania is very dry during boreal summer.

  19. No

  20.  @casualearth-dandavis  If I may ask, does the northern coast of Yucatán peninsula experience upwelling similar to the Guajira Peninsula and ABC islands? It has a strip of semi-arid climate with savanna further inland.

  21.  @JL-ti3us  it's called Geodiode, his climate videos are the creme de la creme.

  22. El Niño does occasionally bring heavy rain to Somalia

  23. ​ @casualearth-dandavis if I may ask, is east and SE Australia more affected by tropical easterlies/northerlies or temperate westerlies? Or does it depend on the season? And what's the source of winter rainfall in the Cfa zones of eastern Australia?

  24. Siberia and China are dry in winter because of the high pressure system known as the Siberia High, not because of the absence of lakes
    2
  25. Because winds are westerly at Patagonia's latitudes

  26. It's not really a desert, it's semi arid

  27. @casualearth9076 is the next video about the climate of the south Atlantic and northeastern Brazil?

  28. I've always wondered where the excess summer rainfall of the Po Valley comes from. Certainly not the west, since lands at the same latitude in western Italy have a Mediterranean climate, not to mention the rain shadow of the Appenines. Do you happen to know by any chance?

  29. There's a video about that on this channel. It's called "why is there a desert in the Caribbean".

  30. I was always confused by the strip of Semi-arid climate in the northern black sea while looking at climate maps. Thanks for clearing up my confusion.

  31.  @casualearth-dandavis  yes I've seen that video of yours, amazing work as always.

  32.  @casualearth-dandavis  quick question though, how far north does this 'anti-monsoon reach? As in where do summer northerlies end and summer westerlies begin?

  33.  @casualearth-dandavis  you misreading my comment just provided me with more information that I didn't know about so there's no complaining about that lol.

  34. At long last

  35.  @pttn6  Mr Davis has already made a video on why the Arabian peninsula is a desert. It's titled "why is there a desert in Somalia"

  36. ​ @casualearth-dandavis is the video on east African deserts still coming up?

  37. It's usually because of a rain shadow. The summer monsoon rains are prevented from reaching southeast India because of the Western Ghats and Eastern Ghats mountains. When the monsoon winds reverse direction in the winter, they pick up moisture from the Bay of Bengal and dump it over southeast India and northeast Sri Lanka, hence the winter precipitation maximum.

  38. ​ @thomasgrabkowski8283 what matters is they don't touch the coast

  39. I completely agree

  40. The Caatinga is dry due to the way in which the ITCZ is positioned over the region, though local geography is also a factor. The ITCZ is positioned north of the region for most of the year, so the northeast trade winds don't really make landfall in that part of Brazil. At the same time, the southeast trade winds lie in the rain shadow of Brazil's coastal escarpment, meaning relatively little rain falls on the leeward side. By contrast, Salvador on the coast has a very wet tropical rainforest climate on the other side of the escarpment. The Caatinga does have a short wet season in spring when the ITCZ moves over the region, though it's not enough to push it out of the semi-arid zone. I hope this was helpful.

  41. I'm not sure if you're going to respond as this is an old video, but if I may ask, why do the Great Plains have dry winters while areas further south and east have no dry season as your map at 5:46 shows, if both of these areas are equally affected by the continental polar air mass from Canada?

  42. Gplates and maptoglobe. The only climate simulation software I've heard of so far is ClimaSim, which only simulates temperature but not precipitation.

  43. I don't know if this is correct or not, bud I'd also argue that we have deserts at such high latitudes in the southern hemisphere is because that hemisphere is mostly water, allowing for greater maritime moderation which prevents temperatures from dropping as low as they do at similar latitudes in the northern hemisphere, and accordingly evapotranspiration doesn't drop as low. Some subarctic areas in the north receive precipitation well below many desert areas but they are not classified as deserts because the cold temperatures always keep evapotranspiration equal to or less than precipitation.

  44. Add to that the rain shadow effect of the Satpura and Vindhya ranges in India to the east and the Sulaiman Mountains of Pakistan in the west.

  45. Continentality

  46. ​ @davidz3879 Somalia is located at the crossroads of two monsoon systems: the South Asian monsoon and the West African monsoon. During the summer, the intertropical convergence zone (ITCZ) shifts far to the north over Asia, leaving behind east Africa and causing the trade winds to blow parallel to its shore as they get deflected to the northeast towards India due to the coriolos force. As they do, they cause upwelling, bringing deep, cold water to the surface, which further reduces precipitation. At the same time, rain-bearing trade winds off the Gulf of Guinea that bring rain to much of West Africa and the Sahel are prevented from reaching east Africa thanks to the rain-shadow effect of the Ethiopian Highlands and the African Rift Mountains. Lastly, the northeast monsoon flow during winter is largely over land, meaning there's little moisture for the winds to pick up. Hope this helps.

  47. New Zealand is in the middle latitudes. This video I specifically about subtropical deserts.

  48. ​​ @casualearth-dandavis At 4:27 you show easterly winds curving into westwrlies over the Congo rainforest. I do know that westwrlies do come off the Gulf of Guineas, but do the westerlies over the Congo originate from the Mascarene or South Atlantic anticyclone? It wouldn't make sense for them to go over the cold Benguela current so far eastward.

  49. ​ @casualearth-dandavis does moisture from the Indian Ocean also reach the Congo Basin from easterly low-level jets that cross through gaps in the Rift Mountains and slow down over Central Africa during Northern Hemisphere summer, similar to the Turkana jet?

  50. In addition to what Mr Davis has mentioned, I'd like to add that in January (Southern Hemisphere summer) the cold Benguela current is at its southernmost extent around the Namib Desert, allowing easterly winds to blow from the Atlantic Ocean into the Congo Basin at this time of year. This is evident in the climate graphs of cities like Libreville, which can receive upwards of 250 mm of rain in January. Hope this clears up some confusion.
