Abstract
It has been pointed many decades ago by C. T. R. Wilson [1920] that sudden reduction of the electric field inside a thundercloud immediately following a lightning discharge should produce an infrasound signature. Recently, Pasko [2009] employed a one-dimensional model to study the electrostatic production of 0.1-1 Hz infrasonic waves from thunderclouds, with particular emphasis on the still poorly understood initial compression phase of the observed infrasonic waveforms. In the present work the results presented in Pasko [2009] are generalized for a two-dimensional cylindrically symmetric case in order to emphasize effects of the finite horizontal extent of the thundercloud source on directionality and morphology of infrasonic pulses observed on the ground.
