Nedbøren

Nedbøren is the term used in Norwegian to denote precipitation, the process by which water is deposited from the atmosphere onto the Earth's surface. It includes several forms such as rain (regn), snow (snø), sleet and hail, as well as drizzle and freezing drizzle. In weather reports and climatological studies, nedbøren is treated as a single phenomenon with multiple manifestations.

In meteorology, nedbøren is quantified as precipitation depth, typically expressed in millimeters of water equivalent. Measurements are taken with rain gauges and snow measurement devices, and are integrated with radar and satellite data for forecasts and hydrological models.

The distribution of nedbøren in Norway varies strongly by geography and season. The western coastal belt experiences high annual precipitation due to moist Atlantic air and orographic lifting, while inland and eastern areas are drier. Snow is common in winter at higher elevations and in northern regions; rain dominates in many coastal areas. Seasonal patterns also differ by region, with wetter winters in some maritime zones and relatively drier summers in others.

Nedbøren supports freshwater resources, ecosystems, and agriculture, but heavy or prolonged precipitation can trigger floods, landslides, and erosion. Long-term changes in precipitation patterns are a focus of climate research, as warming temperatures can alter the distribution and seasonality of nedbøren.
