Global distributions of four air mass zones (shading) and surface precipitation greater than 3 mm day−1 (white contour) in the (a) O–M half-year and (b) A–S half-year. The contour interval is 3 mm day−1. The colors are explained at the bottom. Blank areas indicate regions where the altitude was greater than 775 hPa (about 2000 m). T: Tropical, S: Subtropical, P: Polar, A: Arctic/Antarctic
