Firestorm is a spell that conjures a ring of fire. The caster is able to control the movement and direction of the flames with enough precision to strike specific targets. The spell Partis Temporus can create a gap in the flames to allow safe passage through.
In 1997, Albus Dumbledore and Harry Potter entered a seaside cave in an attempt to locate one of Lord Voldemort's Horcruxes. When the Inferi guarding the Horcrux attacked, Dumbledore conjured a firestorm to drive them back, saving Harry's life in the process.
