These entities form the meanders within jet streams, and they can be classified as baroclinic or barotropic depending on their vertical variation.
Horel and Wallace characterized a "train" of these entities called the PNA pattern, and they can induce alternating flows in the Rhines effect. These entities can pushed into forced stationary modes caused by a meridonal velocity field. Equations governing them usually begin by considering the equation d-dt of quantity zeta plus f, all over h, is equal to zero, which is the principle of potential (*) vorticity conservation. The expression for the velocity of these entities contains the difference of the squares of the zonal and meridonal wavenumbers, and is always westward. These entities form the meanders within jet streams, and they can be classified as baroclinic or barotropic depending on their vertical variation. Their namesake parameter is equal to two omega times cosine of the latitude over the mean radius, and is equivalent to the vertical variation in the Coriolis force. For 10 points, name these large waves of air in the atmosphere, named for a Swedish meteorologist
