Zonal wavenumber is a term used in atmospheric science and oceanography to describe the spatial frequency of wave patterns in a zonal (east-west) direction in a periodic system, like the Earth's atmosphere or ocean. It quantifies how many wavelengths fit into a given distance in the zonal direction.
