  • On the Large-Scale Diffuse Magnetic Field of the Sun 
    Dikpati, M; Choudhuri, A. R (Springer, 1995-10)
    Although the sunspots migrate towards the equator, the large-scale weak diffuse magnetic fields of the Sun migrate poleward with the solar cycle, the polar field reversing at the time of the sunspot maxima. We apply the ...
  • On the Out of Phase Appearance of Large-Scale Diffuse Magnetic Field of the Sun with Respect to Sunspots 
    Dikpati, M; Choudhuri, A. R (Kluwer Academic Publishers, 1996-03)
    We assume the large-scale diffuse magnetic field of the Sun to originate from the poloidal component of a dynamo operating at the base of the convection zone, whereas the sunspots are due to the toroidal component. The ...
  • The solar dynamo with meridional circulation 
    Choudhuri, A. R; Schuessler, M; Dikpati, M (European Southern Observatory, 1997-03)
    In the mathematical form for the coefficient given in the expression (4) in this paper, the value of the parameters d and d should actually be 0.025R/sub0 instead of as printed. We became aware of this typographical error ...
  • The solar dynamo with meridional circulation. 
    Choudhuri, A. R; Schussler, M; Dikpati, M (1995-11)
    We show that meridional circulation can have a profound influence on dynamo models for the solar cycle. Motivated by the observed tilt angles of sunspot groups we assume that the generation of the poloidal field takes place ...
  • Triggering The Birth of New Cycle’s Sunspots by Solar Tsunami 
    Dikpati, M; McIntosh, S.W; Chatterjee, Subhamoy; Banerjee, D; Yellin-Bergovoy, Ron; Srivastava, A (Springer Nature, 2019-02-14)
    When will a new cycle’s sunspots appear? We demonstrate a novel physical mechanism, namely, that a “solar tsunami” occurring in the Sun’s interior shear-fluid layer can trigger new cycle’s magnetic flux emergence at high ...
