Description
The case study describes two events of convection that occurred over Ukraine on 9th and 10th July 2004. Consequently heavy rain and rail were observed.
Content
This case study addresses the formation of a mesoscale convective systems over the Ukraine on 9th and 10th July 2004 associated with heavy rainfall and hail. Cloud top temperatures of up to -70 degrees Celsius were observed. Moreover it should be noted that the Carpathian Mountains played a central role, since the mountain ridge triggered a set of cells.
In this study the development will be observed closely based on satellite imageries and the NWP-field. Since the vertical stratification is essential for the formation of convection, stability indices will be assessed as well.
