17 of the most breathtaking entries from the Weather Photographer of the Year competition
The competition is run by the Royal Photographic Society - the world's oldest photographic society - and the 166-year-old Royal Meteorological Society.
More than 800 photographs were submitted in total and were judged by a panel of six weather and photography experts. Winners were announced at the Royal Meteorological Society's Amateur Meteorologists' Conference in Reading last weekend.
