A 2-year climatology of 296 cold, warm, and occluded fronts from a mesosphere–stratosphere–troposphere radar near Aberystwyth, Wales, reveals that 74% of warm fronts were associated with multiple linear bands representing maxima of vertical wind shear, radar return signal power, or both. In contrast, 51% of cold fronts lacked any such maxima. Similarly, the warm frontal segments of occluded fronts exhibited more banding than the cold frontal segments.
