07 June 1997 - Summary

This case study showed a classic situation for developing thunderstorms. The warm and moist layers in the lower parts of the atmosphere, together with the advection of warm air in these low levels, were ideal for the development of heavy showers. Also diurnal heating played an important role. At the first stage of this development no significant dynamical forcing was present. At a later stage however strong PVA and advection of cold air in the middle and higher levels intensified the development to a real MCS along a squall line.
