Both San Antonio TX and Bismarck ND have the same type of soil - ustolls mollisols. But in San Antonio the average annual air temperature is 21°C, in Bismarck - 6°C. Completely different temperatures but the same soil! But the average annual wind speed and atmospheric pressure are the same (12km/h, 1017mbar). You can see on the map the soil of ustolls from texas to north dakota. So this is proof that air temperature does not affect soil type! Then what about Fayetteville AR? Fayetteville is not located near the Appalachians, but has the same type of soil as Richmond and Montgomery!

I have been to Seoul. I've never been to New York, but I've seen a lot on TV. And the nature in these cities is very similar. You can also compare the cities of Montgomery AL and Richmond VA (both cities have the same type of soil udults ultusols). in both cities average annual wind speed: 10km/h, pressure: 1018mbar. Humidity in Richmond is 66%, precipitation is 1178mm. Montgomery 70%, 1299mm. 1178mm/66%*70%=1249mm. The same amount of precipitation, wind speed, atmospheric pressure, the same type of soil. Unless the average annual temperatures are different: 19°C Montgomery, 15°C Richmond. Apparently the air temperature does not affect soil formation. So far, I have found 3 climatic factors affecting soil formation.

Is climate a factor in soil formation? Is climate type an indication of soil type? Seoul and New York have the same type of soil - udepts (inceptisols). Both cities have the same average annual wind speed and atmospheric pressure (10km/h, 1017mbar). New York has an annual rainfall of 1334mm and 63% relative humidity. Seoul has 1487mm of precipitation and air humidity of 72%, 1487/72*63=1301. Almost the same annual rainfall.
