article_snippet.sent: Upwards lightning is possible, but is very rare - with current estimates suggesting less than one per cent of lightning strikes travelling in an ‘upwards’ direction.
article_snippet.sent: Upwards lightning is very rare - estimates suggest less than 1% of lightning travels in an ‘upwards’ direction.
article_snippet.sent: Upwards lightning is normally caused by a preceding flash moving from the cloud to Earth, and involves a bolt moving from the ground to the clouds.
article_snippet.sent: a preceding flash moving from the cloud to Earth causes an electrical field change, which allows an upward positive leader to originate from a tall object like a building or wind turbine.
article_snippet.sent: During winter snow storms, it is possible for tall objects to initiate upwards lightning without preceding flashes.
