Erratum: Evidence That a Deep Meridional Flow Sets the Sunspot Cycle Period

摘要: An error was made in entering the data. This changes results concerning length of time lag between variations meridional flow speed and those cycle amplitude. The final paragraph on page 667 should read: Finally, we study relationship drift velocities amplitudes hemisphere/cycles. We compare velocity at maximum to amplitude that for hemisphere. There is a positive (0.5) significant (95%) correlation two. However, an even stronger found N + 2 cycle. (0.7) more (99%), as shown. suggestive "memory" solar cycle, again property dynamo models use circulation. Indeed, two-cycle precisely by Charbonneau & Dikpati. behavior is, however, difficult interpret, elaborate this next section. In either case, these correlations only explain part variance (25% current 50% cycle). Obviously, other mechanisms, such gradient rotation rate, also contribute variations. Our investigation possible connections rates 1 3 cycles gives no alternative lags.
