Modification of the Eckman Wind Profile by Roll Circulations
Abstract
Observed wind and temperature profiles used as basic states in models often contain modification by the secondary flow. The correct basic state however, is the one existing prior to the onset of roll development. A low-order spectral model allows for efficient study of secondary instability and its effects on the initial basic state variables. Using an Ekman wind profile as an idealized case, we show that errors in the initial wind profile can lead to significant errors in the model results, particularly in values of the model however, is to observed boundary layers. Arctic leads, boundary layer, mesoscale.
