Mark Boardman is the creator of the StormHour portal for weather and landscape photography. StormHour runs a weekly weather photography competition in association with The Royal Meteorological Society and hosts over 80 ‘Featured Meteorologist’ interviews. Follow them on Twitter or Instagram. An eponym is a word in the English language that is also the name of the person who is associated with their concept, ordinarily that person will have discovered the said concept. I thought I’d run through a few of my favourites and hopefully you can add your own in the comments. So let’s start with Francis Beaufort: Francis Beaufort was a Royal Navy officer and Irish hydrographer who devised his wind scale (Beaufort wind force scale to give it its full name) in 1805 The Beaufort scale ranges from 0 (calm) to 12 (hurricane force) and in its original carnation described the effects of the wind on a Royal Navy Frigate’s sails from "just sufficient to give steerage" to "that which no canvas sails could withstand" Sir Francis died on 17 December 1857, at the age of 83 and his home at 51 Manchester Street, Westminster, London is marked by an historic Blue Plaque should you ever be in the area. Next up the age old question Celsius or Fahrenheit? In the UK we are fans of Celsius, in the US its Fahrenheit. Daniel Gabriel Fahrenheit (German-Dutch-Polish nationality) spent a large part of his life in the early 18th Century designing weather instrumentation but is most famous for developing the Fahrenheit temperature scale. He calibrated his scale on 3 points - the temperature of a mixture of water, salt and ice (0 °F); The freezing point of water (32°F): and the assumed temperature of the human body (96°F) Upside down? The Swedish astronomer Anders Celsius set a scale that had zero as the boiling point of water and 100 degrees as the freezing point, introducing this scale in 1742. The scale was designed to avoid negative temperatures in the winter. However in 1745 the scale was reversed by Carolus Linnaeus and is today still known as the Celsius scale. For fans of trick questions -40 °F and -40 °C are the same temperature!
Milutin Milanković Milanković developed an important theory on long-term climate change relating to the earth’s orbit. The Milanković theory links three periodic changes in the earth’s path around the Sun and the progress of the ice ages. This change is brought about by the earth’s axis wobbling like a gyroscope, tracing a complete circle every 23,000 years (approximately!) After his death in 1958 his theory was generally discredited by the scientific community before new research eventually proved his theory to be accurate in the 1970’s Carl-Gustaf Rossby Rossby waves describe the long, meandering wave patterns of westerly air flow in the troposphere, including the roaming waves within the jet stream and were first characterised by Swedish born American meteorologist Carl-Gustaf Rossby. Rossby was the first meteorologist to appear on the cover of a major magazine when he was featured Time in December 1956

Bergeron–Findeisen, The Bergeron–Findeisen process (sometimes known as Wegener-Bergeron–Findeisen process) is the development of precipitation due to the presence of ice crystals in the cloud. It most often occurs in mid to high latitudes where supercooled water droplets and ice crystals happily coexist. Tor Bergeron was a Swedish meteorologist born in Surrey and Walter Findeisen was a German scientist. They studied and documented the process in the 1930’s.
