| Abstract | This paper presents a short overview of our current understanding of the generation of charged particles in different environments and circumstances (e.g. thunderclouds, dust storms, volcanic plumes, rings, and planetary surfaces) and the subsequent spatial separation that leads to the formation of electrical fields. Different mechanisms are involved on various scales, starting from the molecular level, through the single particle (droplet, crystal, solid) and finally the entraining volume (cloud, plume etc.). Encapsulated within a dynamic and turbulent medium, particles need to come into contact and to immediately separate, to be later transported away from each other. In order to explain the observed electrical fields and ensuing lightning or other forms of discharge, these processes need to be extremely effective. The section will briefly review laboratory results and modeling efforts of charge separation and electric field build-up in various planetary settings, and cite the appropriate observations of electrical activity on different planets. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
