Meridional Circulation and the Solar Magnetic Cycle
The Sun’s magnetic cycle manifests itself in an year periodic variation in the number of sunspots seen on the solar surface and a periodic reversal in the polarity of its large-scale magnetic fields. Exploring the origins of this magnetic cycle can unravel the physical mechanisms at work in the interior of magnetized stars like the Sun. Such studies are also important for understanding how the ...
متن کاملCoherent surface-subsurface fingerprint of the Atlantic meridional overturning circulation
[1] Satellite altimeter data shows a weakening of the North Atlantic subpolar gyre during the 1990s, which is thought as an indicator of a slowdown of the Atlantic meridional overturning circulation (AMOC). However, whether the recent slowing subpolar gyre is a decadal variation or a long-term trend remains unclear. Here I show that altimeter data is highly correlated with instrumental subsurfa...
متن کامل5. the Mean Meridional Circulation
(3) Here the square brackets denote zonal means, RΤ is the net radiation at the top of the atmosphere, and a time average has been used to eliminate the tendency term. Eq. (3) expresses the requirement of total energy balance for a “ring” of air along a latitude circle. By further integration of (3) with respect to latitude, we can obtain the meridional energy transport by the atmosphere, with ...
متن کاملAtlantic Dominance of the Meridional Overturning Circulation
North Atlantic (NA) deep-water formation and the resulting Atlantic meridional overturning cell is generally regarded as the primary feature of the global overturning circulation and is believed to be a result of the geometry of the continents. Here, instead, the overturning is viewed as a global energy–driven system and the robustness of NA dominance is investigated within this framework. Usin...
متن کاملOn the stability of the Atlantic meridional overturning circulation.
One of the most important large-scale ocean current systems for Earth's climate is the Atlantic meridional overturning circulation (AMOC). Here we review its stability properties and present new model simulations to study the AMOC's hysteresis response to freshwater perturbations. We employ seven different versions of an Ocean General Circulation Model by using a highly accurate tracer advectio...
