On Thunderclouds

Philosophy of Photography, 2023
Landscapes and atmospheric processes are rapidly changing, and so are the technologies we use to depict and detect them. How to ponder these transformations through artistic thinking and making? In the artwork On Thunderclouds, I examine the thundercloud as aesthetic motif, meteorological phenomenon, and as an ominous sign of climate change.

Electric field growth in thunderclouds

Quarterly Journal of the Royal Meteorological Society, 1975
AbstractWe have constructed a balloon‐borne instrument for measuring the magnitude of the horizontal component of the electric field in thunderclouds. It consists of two hollow, copper spheres 15cm in diameter held 2cm apart. The spheres spin about an axis that can be described as the perpendicular bisector of the line segment between the centres of ...

Formation of Thunderclouds

2014
Almost everyone is familiar with cumulus clouds (Fig. 5.1a), which look like a piece of floating cotton, with a sharp outline and a flat bottom. When a growing cumulus resembles the head of a cauliflower, it is called a cumulus congestus (Fig. 5.1b).

Autowave Regimes of Thundercloud Electrification

Radiophysics and Quantum Electronics, 2001
We consider the evolution of the electric field and charge in a one-dimensional electrohydrodynamic (EHD) distributed-parameter system which serves as a simple model of a thundercloud. A diffusion equation for the electric field is proposed which, under reasonable assumptions on the nonlinear dependence of the dissipation current on the electric field (

Stepped leader characteristics in developing horizontally within thunderclouds and in descending out of thunderclouds

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
We examine VHF and optical images of cloud-to-ground flashes to study IC leaders that propagated within thunderclouds and CG leaders that descended outside thunderclouds. It is shown that IC leaders developed smoothly and CG leaders propagated in a heavily branched manner.

A theory of thundercloud electricity

Proceedings of the Royal Society of London Series A, Mathematical and Physical Sciences, 1956
The thundercloud is regarded as a great influence machine, the ionization currents associated with it being the agents by which its electromotive force is developed and maintained. The moving ions which constitute these currents may be intercepted by solid or liquid cloud elements so that it becomes possible for them to be carried against the field and

Thundercloud pre-stroke electrostatic modeling

Journal of Electrostatics, 2002
The electric field in a short gap for a known volume charge distribution is initially investigated, enabling the limits of application and the accuracy of an approximate version of a rigorous field formulation to be examined. The approximation substantially consists in neglecting possible charge density gradients in the volume occupied by the charge ...

Fractal dynamics of electric discharges in a thundercloud

Physical Review E, 2003
We have investigated the fractal dynamics of intracloud microdischarges responsible for the formation of a so-called drainage system of electric charge transport inside a cloud volume. Microdischarges are related to the nonlinear stage of multiflow instability development, which leads to the generation of a small-scale intracloud electric structure ...

Atmospheric Disturbances due to Thundercloud Discharges

Nature, 1937
IT is generally recognized that the phenomenon of lightning is extremely complicated, and many attempts, notably by Schonland1, using a special camera, have been made to analyse and classify lightning flashes.
