the climate of western europe is a predominantly a marine climate
Oceanic climate It typically lacks a dry season, as precipitation is more evenly dispersed throughout the year. It is the predominant climate type across much of Western Europe, the Pacific Northwest region of the United States and Canada, portions of central Mexico, southwestern South America, southeastern Australia including Tasmania, New Zealand as well as isolated locations elsewhere. Oceanic climates generally have warm summers and cool (but not cold) winters. They are characterised by a narrower annual range of temperatures than are encountered in other places at a comparable latitude, and generally do not have the extremely dry summers of Mediterranean climates or the hot summers of humid subtropical.[1] Oceanic climates are most dominant in Europe, where they spread much farther inland than in other continents.[2]
World Ocean The unity and continuity of the World Ocean, with relatively free interchange among its parts, is of fundamental importance to oceanography.[2] It is divided into a number of principal oceanic areas that are delimited by the continents and various oceanographic features: these divisions are the Atlantic Ocean, Arctic Ocean (sometimes considered a sea of the Atlantic), Indian Ocean, Pacific Ocean, and Southern Ocean, defined by the International Hydrographic Organization (IHO) in 2000, based on evidence that this region of the World Ocean has a distinct ecosystem and a unique impact on global climate.[3]. In turn, oceanic waters are interspersed by many smaller seas, gulfs, and bays.
