On 10 June 2013, a severe thunderstorm that produced large hail moved across parts of Hungary. The authors observed that the orientation of the ice plume produced by the storm changed during its late development stage. The causes for this behavior are analysed through an analysis of the storm motion vector and the wind vectors. Here is the report in pdf-format. In addition, a Powerpoint presentation and two animations (satellite, radar) illustrate the case.
