vindbrist

Vindbrist is a term used in some Nordic and Dutch-language meteorology and energy contexts to denote a period of unusually light or absent wind in a given area. The term combines vind (wind) with brist (shortage) and is used to describe sustained lulls that can last from several hours to several days. In weather reports and energy planning, vindbrist refers to times when surface winds fail to reach speeds sufficient for practical use or for efficient wind power generation.

Causes of vindbrist include persistent high-pressure systems that produce a weak pressure gradient and light geostrophic winds. Local factors such as stable atmospheric layers, nocturnal temperature inversions, and terrain effects can amplify calm conditions. Seasonal patterns and coastal sea–land interactions can also contribute to recurrent wind lulls in specific regions.

Impacts vary by sector. For wind energy, vindbrist can sharply reduce production, as many wind turbines start generating power only above a certain cut-in speed and deliver little output at very low winds. This can create shortfalls in electricity supply and increase the need for balancing measures, such as importing power or using other generation sources. Outdoor activities that depend on wind, including sailing and kitesurfing, may be delayed or canceled during vindbrist periods.

Forecasting and management involve meteorological models and energy planners working together to predict the onset and duration of vindbrist, enabling grid operators to prepare for potential supply gaps and adjust operational strategies accordingly.
