Wave Intensity Analysis separation into forward travelling waves (top) and backward travelling waves (bottom) is displayed, using the SG-D approach (a), the SG-S approach (b) (N = 2, M = [3, 15]) and the central finite difference one (c). The significant flattening of the main waves caused by the increase of smoothing (a–b) introduced is clearly visible. The WI_± units are W m⁻² s⁻².
