Editing Geography of Norway (section)

=== Precipitation ===
Norway is among Europe's wettest countries, but with large variation in precipitation amount due to the terrain with mountain chains resulting in orographic precipitation but also creating rain shadows. In some regions, locations with vastly different precipitation amounts can be fairly close. Precipitation is heaviest in late autumn and winter along the coast, while April to June is the driest. The innermost parts of the long fjords are somewhat drier. The regions east of the mountain chain (including [[Oslo]]) have a more continental climate with generally less precipitation, and precipitation peaks in summer and early autumn, while winter and spring tend to be driest. A large area in the interior of Finnmark receive less than {{convert|450|mm|1|abbr=on}} of precipitation annually. Some valleys surrounded by mountains get very scarce precipitation, and often need irrigation in summer.
