sekundærrunt

Sekundærrunt is a term used in meteorology to describe a secondary, often less intense, wave-like disturbance that follows a primary weather system, particularly a cyclone. This phenomenon is not a distinct weather event but rather a feature associated with the development and decay of larger-scale weather patterns. When a primary low-pressure system moves through a region, the associated atmospheric dynamics can leave behind residual energy and vorticity. Under favorable conditions, this residual energy can organize into a secondary trough or wave that propagates behind the main system.

These sekundærrunt features are typically characterized by weaker pressure gradients and less precipitation compared to the preceding primary system. They can sometimes lead to localized areas of unsettled weather, such as scattered showers or a slight increase in wind, but they rarely develop into significant storms on their own. Their presence can indicate a complex interaction of atmospheric forces and the lingering effects of a more substantial weather event. Observing sekundærrunt helps meteorologists refine forecasts by accounting for these secondary influences on local weather conditions. The term itself is of German origin, meaning "secondary wave" or "secondary run."
