Abstract: Techniques and instrumentation for studying atmospheric electric field including the working principle of the field mill employed for the present investigation are outlined. The variations of the electric field as observed over Kolkata during unusual meteorological disturbances are reported. During local precipitation, a significant reduction of electric field is noticed in the records, while in the occasions of local thunderstorms there is a pronounced increase of the electric field, sometimes, even showing a very intense value of more than 600 vm-1. The results have been discussed in the light of the source activity and further problems are focused.
