Rain in Korea almost always seems to from the South. It comes as part of tropical storm systems rising up the east coast of Asia, similar to the way the Eastern US gets hurricanes and hurricane-related lesser weather systems in the summer. Today, though, the rain came as a kind of blurry, non-cyclonic blob from the northwest. This is interesting – it's rain on a cold front instead of on a warm front, for one thing – so the weather actually cooled as the rain arrived, whereas normally here the weather gets warmer when the rain arrives. This cool, northwestern-origin rain felt like midwestern or Pacific northwest rain in the US. Refreshing.
