Examples of model 1-AU solar wind structure at solar minimum (left) and solar maximum (right). Top: solar wind speed at 1 AU as a function of latitude and longitude. The yellow curve shows the heliospheric current sheet. Second row: same as top, but a zoom in of 15° about the heliographic equator. White, red, and black horizontal lines show 0°, 3.5°, and 7° latitude, respectively. Third row: solar wind speed at the three highlighted latitudes, in the same format. Bottom: the difference in solar wind speed between a given latitude and the equator. Figure adapted from Owens et al. (2019a).
