Anvil Crawlers
Anvil CrawlersAnvil Crawlers are horizontal, tree-like, in-cloud lightning discharges whos leader propagation is resolvable to the human eye. In other words, the anvil crawler's movement is slow enough (compared to most lightning discharges) that a human observer or normal-speed video camera can see its rapid motion across the sky. This type of lightning (sometimes referred to as 'crawlers' or 'rocket lightning') often cover very large distances, resulting in vast, spectacular sky-filling discharges.
Anvil crawlers are often very high-altitude events, and as such typically result in soft, rolling thunder due to their great distance from the observer. The name 'anvil crawler' is derived from the visible 'crawling' motion and their tendency to appear along the underside of the anvil portions of a thunderstorm. Anvil crawlers can either occur independently completely within the cloud, or in connection with a cloud-to-ground discharge. They may have also slowed it down ato
