Abstract : An investigation has been carried out with the aim to compare some different types of whistlers and their relations to thunderstorm activity. It was found that the same thunderstorm region produced usual as well as unusual and mixed variational forms of whistlers. The production of the different types proved to be independent of the geographical positions of the active thunderstorm regions. By the aid of different characteristics of lightning discharges it was not possible to draw conclusions as to why different types of whistlers were produced. The reason must be sought in some other beophysical phenomena, and only further systematic experimental investigations will give an answer to this question. (Author)
