The solar wind speed at Earth normally lies around 300km/sec but increases when a coronal hole high speed stream (CH HSS) or coronal mass ejection (CME) arrives. During a coronal mass ejection impact, the solar wind speed can jump suddenly to 500, or even more than 1000km/sec.
These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 kilometres per hour (580 m/s; 1,300 mph).
