Meridional transport of mean zonal kinetic energy from five years of hemispheric data

The mean zonal kinetic energy transports across arbitrary latitude walls in the northern hemisphere are evaluated from five years of data. It is found that the stress-work processes at the boundaries are much more significant than the actual advection of zonal kinetic energy. The stress component associated with the earth’s rotation accounts for a net northward transport of zonal kinetic energy across the equator.
