Vertical mean distributions (925–775 hPa) of the temperature (K; contour) and specific humidity (g kg⁻¹ \(;\) shading) in the (a) O–M half-year and (b) A–S half-year for 1981–2020. The contour interval is 5 K. The scale of shading is shown at the bottom, and the warm and cold colors indicate relatively high and low specific humidity, respectively
