In 2012, he reported new details on how this meridional flow might regulate magnetic fields at the sun's poles.
For decades, scientists had assumed that the meridional flow traveled at a depth of about 200,000 kilometers below the sun's surface.
The mechanism, known as meridional flow
, works something like a conveyor belt.
Among specific topics are an immersed boundary method for simulating compressible viscous flow in complex geometries, the numerical study of battle damaged two-dimensional wings, the meridional flow
of grounded abyssal currents on a sloping bottom in spherical geometry, acoustic frequency for bubble size correlation using acoustic emissions, and using heart blood flow analysis in clinical practice.
The duration of a solar cycle is probably determined by the strength of the sun's meridional flow, according to scientist Mausumi Dikpati.
The combination of the meridional flow and the lifting and twisting of magnetic fields near the bottom of the convection zone generates the observed symmetry of the sun's global field with respect to the solar equator.
When the meridional flow
of the PNA positive mode occurs, Ohio winters are consistently drier than normal and stream flow is typically about 50% of the PNA wet winters.
A new meridional flow
path shape allows a higher average peripheral speed which in turns means a lower stage work coefficient with a reduced number of stages.
The dominant components of the meridional flow
of cold water are western intensified both within the Atlantic and within its subbasins, which are defined by abyssal ridges.
Hathaway and other researchers say they're now convinced that a flow of ionized gas, or plasma, known as the meridional flow
controls the strength of the solar cycle (SN: 4/10/10, p.
The relatively slow gas movement, known as the meridional flow
, sped up a few years before the latest minimum in solar activity began in 2008, the researchers reported in the March 12 Science.
Topics include deep meridional flows
and their relation to dynamo models; surface magnetic effects on seismic inferences; latest asteroseismic results from space; recent numerical simulations of convection and magnetic fields; and helioseismic, asteroseismic, and other data in solar models.
