I have occasionally pondered the similarities and differences between these two cities (shown above as close as I can to the same scale). I think there are more differences than similarities. Both are the biggest city in their country, but Seoul comprehensively so and Sydney only just (and is projected to be overtaken by Melbourne sooner rather than later). Seoul is the capital of South Korea, but Sydney isn’t the capital of Australia, even though many people around the world think or assume it is. As a result, Sydney (and/or Melbourne) dominate economically and culturally, but not politically (at least at the national level; they dominate their respective states).
Geographically, both sit between the ocean and mountains. Even though South Korea is overall more mountainous, Wentworth Falls (at the far left of the Sydney map) is higher in elevation than Bukhansan. It’s just that Bukhansan is located comparatively much closer to its city. (Also, Mount Kosciuszko (the highest mountain on mainland Australia) is higher than Hallasan, and Mawson Peak (the highest on an outlying territory) is (just) higher than Mount Baekdu.) Both are at similar latitudes (Seoul 37ºN and Sydney 33ºS), but Seoul’s weather is dominated by the Siberian high and East Asian monsoon, meaning very cold winters (with snow) and very wet summers (with occasional typhoons) while Sydney’s is more equable, very rarely getting super-cold or super-hot (at least towards the coast; my inland suburb is more variable, and one day a few years ago a suburb near here was the hottest place on the planet).Continue reading
