This theory can be applied for the both waves. In the beginning there is a classical cold front and due to the suitable conditions a occlusion developed from the cold front cloud band. The cold air moves south-eastward and warm air moves north-westward and this circulation is superimposed on the eastward-moving front. During this circulation a strengthening of the low pressure area occurs and further development of a new cyclone can be observed.
For both waves this theory has an important role. Cloud bulges of both waves are developing in the left exit region of a jet streak.
The downward protruded dry air which overruns a low level baroclinic zone has a very important role in both wave development. This can be seen in WV images, in relevant model fields like potential vorticity (PV) and in vertical cross sections (especialy for the second wave development).
