New Zealand is caught between a high-pressure system (H) in the subtropical belt to the north, and a zone of strong westerly winds south of the country. Shown along the contour lines are the mean air pressures (1971–2000) at sea level. The winds blow parallel to the lines, and are stronger where the contours are closer. The high-pressure system moves north and south with the seasons.
