Ulsan has a monsoon -influenced humid subtropical climate ( Köppen Cfa / Cwa ), with cold but dry winters, and hot, humid summers. Monthly means range from  °C ( °F) in January to  °C ( °F) in August, with diurnal temperature ranges generally low. Its location on the Korean peninsula results in a seasonal lag. The warmest days occur in August and averaging very near 30 °C (86 °F). Precipitation is relatively low in the winter months, but there is high rainfall from April to September.

In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields. [38] In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system. [39] The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position. [37] In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.
