The Δ 14C series of yearly sampled cosmogenic 14C in wines (1909–1952) was analyzed with the Fourier Vector Amplitude (FVA) method, using cyclograms as a graphic tool, to find information on periodicities imprinted by the sun. Because the high sensitivity of the FVA algorithm in detecting periodicities and their variations is emphasized by immediate visualization of its cyclograms, a suggestion has been found for a modulation event. Data are compared with a frequency modulation model, the extension of which to the long 9000–a Δ 14C series suggests a first approach to interpret the Suess wiggles.
