Poleward eddy heat and momentum fluxes at 100 hPa, area-averaged over the latitude belts from 45°N to the pole during the winter season for zonal wavenumbers 1 and 2

	DJF	High	Low	Hi-Lo
Heat 1	115	94	145	−50
Heat 2	69	109	48	61
Momentum 1	−47	−29	−113	84
Momentum 2	−45	101	−75	176

First column is the seasonal mean for all data (DJF), followed by the 1.5 standard deviation high composite (High), low composite (Low), and the difference between them (Hi-Lo). Units are °K⋅ms⁻¹ for heat flux and m²⋅s⁻² for momentum flux.
