Example of the simulated solar wind speed. a An example of the simulated solar wind speed at each grid located along the Sun–Earth line. b Solar wind speed at the Earth derived by simulation runs with CMEs with an initial speed derived from CACTus max speed (blue), the LASCO catalog (red), and eight CMEs with initial speeds that are faster or slower than the CME speed in the LASCO CME catalog with a 100-km/s interval (black). Vertical line indicates the arrival time of each CME at the Earth
