The wavelength spectrum of striations in ionized barium clouds has been the subject of interest recently. It is somewhat puzzling that striations tend to have wavelengths (perpendicular to the ambient magnetic field) of order 1 km, whereas the simplest linear one-dimensional estimates indicate insignificant wavelength variation of the striation growth rate. Recent calculations explain this behavior on the basis of growth rates obtained when one considers striation modes whose electric field is the same at the E and F layers of the ionosphere as it is at the barium cloud. However, other calculations show that, when one considers the self-consistent modal variation along magnetic field lines with barium clouds, the growth rates are if anything slightly increased as the wavelength decreases from 1.0 to 0.1 km.
