Negative cloud-to-ground brings down negative charge from cloud to ground. In this paper, observations of the characteristics of fast and slow electric field within reversal distance (less than 7-8 km from lightning sensor) are reported. A total of four negative cloud to ground lashes detected very ...

Rheology is already defined as the science of flow and deformation of matter. The purpose of rheology is to look at the relationships between stress and deformation of the material-marterial (non-Newtonian) in order to explain its mechanical properties. One of the ingredients that is often used as a...
