Prince of Wales, Weatherman of Scotland Most of the world may know him as Charles, Prince of Wales, but the heir to the British throne is also known, in the land north of Hadrian's Wall, as the Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland. On Thursday, during a tour of the BBC Scotland headquarters in Glasgow, Prince Charles briefly adopted one more title: Royal Weatherman.
