对比美国西海岸的西雅图与旧金山,很明显你就能分辨出海洋性与地中海气候
一句话解释两气候:
西雅图人对旧金山人说:i like your weather
旧金山人对西雅图人说:i like your rain
一下来自维基:

Dry summer variety (Csb)[edit]
Seattle
Despite the fact that dry summers are a feature which differentiate Csb areas from oceanic climates, some areas of Csb climate are typically considered "oceanic" as opposed to "Mediterranean" (see Mediterranean climate). Technically, this version of the Oceanic climate meets Koppen's minimum precipitation threshold limit of 30 millimetres (1.2 in) (or 40 millimetres (1.6 in) under Koppen-Geiger), resulting in a Csb designation. Nevertheless, due to the higher annual accumulation of precipitation and generally cloudier conditions that these regions experiences in comparison to other areas with Csb climates, a number of scientists consider this climate oceanic. This is especially the case in the Pacific Northwest region of the United States and Canada, some sections of coastal Chile, in Galicia in northwestern Spain and in northern Portugal, where conditions are wetter and generally cloudier during the course of the year than typical Csb climates.[citation needed][13] Nevertheless, those regions have several Mediterranean features :
Greater annual hours of sunshine than the typical oceanic domain, especially during the drier summer months, sometimes unbroken sunny stretches for weeks at a time under the dominating influence of stable high pressure. For example, cities such as A Coruña or Seattle have at least 2000 hours of sunshine, while the values of the typical Cfb regions are almost always below 2000 hours.[14][15]
Vegetation which is partially adapted to xeric conditions. So the cork oak, a typically acidophilus Mediterranean species, and which is widely distributed in Portugal and in southern-half of Galicia.[16] In contrast, beech or birch, widely distributed in the Cfb area, are not common in Iberia, mostly confined to the Pyrenees and the Cantabrian mountains. In addition, Garry oak, typical of California, can be found as far north as Vancouver Island.[17][18] Douglas fir, which is the typical species of the Pacific Northwestern forests, is very well adapted to the summer drought.[19]
Forest fires are regular in those regions due to the summer drought.[20][21]
