Convection inhibition
Convective inhibition (dt "convective inhibition."; Abbreviated CIN , CINH ) is in the meteorology the energy that an air parcel overcome needs to the level of free convection ( english Level of Free Convection , LFC to reach), d. H. to continue to ascend independently. It is a measure of the stratification stability of the atmosphere and is given in the dimension of joules per kilogram (J / kg).
In a stable stratification, an air parcel that is lifted is colder and therefore denser than its surroundings and therefore experiences negative buoyancy. In order to trigger free convection , CIN must be applied by other processes (e.g. convergence , orographic uplift , heating). In principle, a high CIN value means that there is less tendency for cumuli or thunderstorms to form .
