Scientific paper

Irregular sporadic E layers have been observed by the Arecibo incoherent scatter radar and a coherent scatter radar imager located on St. Croix during the passage of MSTIDs also seen by the Boston University all-sky imager. Radar imagery shows that coherent scatter from small-scale irregularities in the sporadic E layers often arrives from wavelike bands that are frequently, but not always, aligned in the northwest-to-southeast direction. The intensity of the coherent scatter appears to be modulated by the MSTIDs. The coherent scatter Doppler shifts are meanwhile highly correlated with altitude displacements in the sporadic E layers, with the sign of the correlation being controlled by the sign of the background zonal electric field. The MSTIDs do not generally appear to modulate the morphology of the sporadic E layers themselves, which most often take the form of convective rolls drifting with the ambient neutral wind. The lower thermospheric neutral winds inferred from the incoherent scatter data are typically dynamically unstable in the Richardson number sense, offering a partial explanation for the mechanism that initiates irregularity formation.
