Tracking of storm cells has been frequently performed using radar and/or satellite data. It received less attention using model data. We present storm cell tracks for 6 cases of severe convection in 2011, 2012 and 2013 simulated using the non-hydrostatic COSMO-DE weather model. The cases are selected with a different synoptic background, i.e. different background shear and CAPE. For each of the cases vertical velocity maxima are tracked. Composites of the typical evolution of a storm cell are made.
There is a relatively large variability between the characteristics of individual cells. However, the PV dipole associated with the storm updraft is clearly visible in the composites. When we cluster on the strength of CAPE, the differences between the composites with large and small CAPE values are small. However, clustering on other intensity measures like PV, vertical velocity or precipitation rates gives, for intense cells, composites with a supercell structure i.e., a relatively strong rotating updraft. The results show that PV, unlike CAPE, might be a good predictor for intense convective cells, and motivates the use of PV on smaller scales.
