Abstract

THE zonal harmonics in the Earth's gravitational field indicate its variations with latitude, averaged over all longitudes. The odd zonal harmonics, of degree 3, 5, 7, …, specify that part of the gravitational field which is not symmetrical about the equator and gives rise to the “pear-shape” effect.
