Why does it often take a long time for a temperature inversion to end?

A temperature inversion can persist for an extended period due to stable atmospheric conditions that trap warm air above cooler air near the surface. This stability prevents vertical mixing in the atmosphere, inhibiting the dispersion of cooler air and pollutants. Additionally, persistent high-pressure systems can maintain these conditions, limiting the influence of weather patterns that might otherwise disrupt the inversion. As a result, it may take a significant change in weather, such as increased wind or a shift in temperature, to break the inversion.
