They are named after two physicists - Hermann von Helmholtz and William Thomson, who was also known as Lord Kelvin - studied the physics behind cloud Met Office said: "Kelvin Helmholtz clouds, or fluctus clouds, are quite rare."These clouds are more likely to be seen on windy days when there is a difference in density of the air."They also indicate instability in the atmosphere, which can help identify areas of turbulence for aircraft."They added: "This phenomenon, whilst rare, has also been spotted in cloud patterns on Jupiter, within Saturn's bands and on the sun's corona."
