• Met Office explains: How is thunder formed?

  Thunder is one of nature’s most dramatic sounds, accompanying brilliant flashes of lightning during a storm. But what causes this rumbling roar in the sky? To understand thunder, we must first explore the processes that lead to its formation—starting with the clouds that produce it. The role
