Movement of convective systems
Individual cells movement can be approximated using the mean wind
Movement of an MCS is dependent on, 1) the mean flow between 850-300 mb (Corfidi, 1994), and 2) the rate new cells are growing (propagation)
The propagation rate is strongly dependent on the low-level jet but is also dependent on the strength of the cold pool
The stronger the low-level jet (compared to the mean wind), the more the MCS will deviate from the mean wind.
