Role of observable nonlinearities in solar cycle modulation
M. Talafha, M. Nagy, A. Lemerle +1
Context. Two candidate mechanisms have recently been considered for the nonlinear modulation of solar cycle amplitudes. Tilt quenching (TQ) is a negative feedback between cycle amp…
The polar precursor method for solar cycle prediction: comparison of predictors and their temporal range
Pawan Kumar, Melinda Nagy, Alexandre Lemerle +2
The polar precursor method is widely considered to be the most robust physically motivated method to predict the amplitude of an upcoming solar cycle.It uses indicators of the magn…
Towards an algebraic method of solar cycle prediction II. Reducing the need for detailed input data with ARDoR
Melinda Nagy, Kristóf Petrovay, Alexandre Lemerle +1
An algebraic method for the reconstruction and potentially prediction of the solar dipole moment value at sunspot minimum (known to be a good predictor of the amplitude of the next…
Towards an algebraic method of solar cycle prediction I. Calculating the ultimate dipole contributions of individual active regions
Kristóf Petrovay, Melinda Nagy, Anthony R. Yeates
We discuss the potential use of an algebraic method to compute the value of the solar axial dipole moment at solar minimum, widely considered to be the most reliable precursor of t…
Impact of rogue active regions on hemispheric asymmetry
Melinda Nagy, Alexandre Lemerle, Paul Charbonneau
The solar dipole moment at activity minimum is a good predictor of the strength of the subsequent solar cycle. Through a systematic analysis using a state-of-the-art 22 D s…
Rogue active regions and the inherent unpredictability of the solar dynamo
K. Petrovay, M. Nagy
New developments in surface flux transport modeling and theory of flux transport dynamos have given rise to the notion that certain large active regions with anomalous properties (…
Precursors of an upcoming solar cycle at high latitudes from coronal green line data
K. Petrovay, M. Nagy, T. Gerják +1
After reviewing potential early indicators of an upcoming solar cycle at high latitudes, we focus attention on the rush-to-the-poles (RTTP) phenomenon in coronal green line emissio…
The Effect of "Rogue" Active Regions on the Solar Cycle
Melinda Nagy, Alexandre Lemerle, François Labonville +2
The origin of cycle-to-cycle variations in solar activity is currently the focus of much interest. It has recently been pointed out that large individual active regions with atypic…
Oscillator models of the solar cycle: Towards the development of inversion methods
Ilídio Lopes, Dário Passos, Melinda Nagy +1
This article reviews some of the leading results obtained in solar dynamo physics by using temporal oscillator models as a tool to interpret observational data and dynamo model pre…
Oscillator Models of the Solar Cycle and the Waldmeier Effect
M. Nagy, K. Petrovay
We study the behaviour of the van der Pol oscillator when either its damping parameter or its nonlinearity parameter is subject to additive or multiplicative random noise.…
