  Scotland. Anticyclones normally bring settled weather, however the seasons and origin of the airmass often result in differences in cloud cover. For example, whilst we associate high pressure as bringing fine sunny weather to the UK during the summer, the same high pressure can lead to extensive

• 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
