Fig.4 Composite patterns of the atmospheric response by the Pressure Adjustment mechanism type for 303 anticyclones(a，c，e) and 517 cyclones (b，d，f)[17] Colors in (a)~(d) are negative vertical velocity in pressure coordinates, positive values indicate upward motion; Contours in (a) and (b) are specific humidity, contours in (c) and (d) are vertical eddy heat. Unit of vertical velocity is 1×10-2 Pa/s, unit of specific humidity is 1×10-3 J/(kg·s), Q12’ is 1×10-2 g/kg; All values shown without an asterisk are significantly different from zero at the 99% confidence level based on t testing; (e), (f) The composite SST profiles along the background wind direction across eddy centers, R is the eddy radius
