Abstract
By extending the parameter range of the previous numerical stability analysis of convection rolls (Clever and Busse, 1974) a new instability has been found. In low Prandtl number fluids this instability, called the skewed varicose instability, causes an increase of the wavelength of convection rolls with increasing Rayleigh number. A comparison between theoretical results and experimental observations shows good agreement.
