![]() ![]() Cloud to ground lightningĪs the lower part of the clouds are negatively charged, and like charges repel each other, negative electrons in the ground are forced away, making the ground and some objects positively charged. This forms an in-balance in the distribution of charge, with the lower section being more negatively charged, and the upper more positively. The smaller particles become positively charged (due to stripped electrons) and stay towards the top of the cloud. As a result, the ice crystals become negatively charged and fall to the bottom of the cloud. While falling, the ice crystals ‘strip’ other particles of electrons. The crystals grow in size to a point where the uplift forces cannot continue to elevate them, as such they fall back down. Consequently, these particles cool to form ice crystals such as hail. However, the prevailing theory is as follows Uplifts of air within the clouds move particles towards the top. The cause of the electrostatic discharge is not 100% proven. Positive charged lighting causing a bolt from the blue. A bolt from the blue is cloud to ground lighting. Intra-cloud lightning, cloud to cloud lightning, and cloud to ground lighting. Lightning occurs in three common forms (though there are ‘exotic’ types of lightning such as ball lightning). Simply put, lightning is an electrostatic discharge, which occurs during an electrical storm think of a giant electrical spark which may occur when a charge jumps from one object to another. In order to explain how a bolt from the blue forms, we much first understand how lighting forms and what it is. While bolts from the blue don’t originate from blue sky, they occur infrequently, are unexpected, and can be deadly. The phrase is actually based on real weather phenomena where a lightning bolt will strike an area with no overhead clouds. ![]() ![]() When an unexpected event happens people describe it as a “bolt from the blue”. This strike was part of a storm and not a bolt from the blue. Lightning striking ferris wheel in Liverpool. ![]()
