  Lightning from Cumulonimbus capillatus

  Lightning strikes to the ground, known as ground discharges, are seen from the lower part of this Cumulonimbus cloud. The cloud is specifically identified as Cumulonimbus capillatus incus by the fibrous top to the cloud and anvil (coding CL = 9). Other lightning activity is occurring within the thundercloud cloud (intra-cloud lightning), with some cloud discharges lighting up the interior. One lightning flash – an anvil crawler – originates from the upper portion of the cloud, beneath the anvil, and travels horizontally for some distance, generating several branches.

  Thunderstorm

  A tropical depression over the northern part of the South China Sea intensified into a tropical storm named Mirinae. In Hong Kong (China), the weather was hot with sunny periods during the day and there were also a few squally showers and thunderstorms.

  Thunderstorms are associated with Cumulonimbus clouds and are most often accompanied by precipitation. This photograph shows a thunderstorm during the evening from a Cumulonimbus calvus cloud. A thunderstorm is defined as one or more sudden electrical discharges, manifested by a flash of light (lightning) and a sharp or rumbling sound (thunder).

  “Anvil crawler” lightning

  This picture shows lightning branching through the anvil of a strong mid-level thunderstorm over Lincoln, Nebraska, USA. These cloud discharges are colloquially known as ”anvil crawlers”.

  A rain-free updraught base can be seen at the right-hand side of the image. Elsewhere, cloud detail is masked by heavy precipitation. Shafts of precipitation are evident near to the rain-free updraught base.

  Lightning: cloud discharges

  This picture shows cloud discharges of lightning at 1 and 2 during an evening thunderstorm over Nebraska, USA. The thunderstorm was rather high-based, and mamma can be seen in the distance where part of the extensive anvil of the storm is visible. A small updraught base is visible at the lower right, with cumuliform clouds growing into the storm. Cumulus fractus clouds are evident underneath the storm, with other Cumulus species in the distance.
