Why does the sun's torsional oscillation begin before the sunspot cycle?
Although the Sun's torsional oscillation is believed to be driven by the Lorentz force associated with the sunspot cycle, this oscillation begins 2-3 yr before the sunspot cycle. We provide a theoretical explanation of this with the help of a solar dynamo model having a meridional circulation penetrating slightly below the bottom of the convection zone, because only in such dynamo models does t...
متن کاملThe shape of the sunspot cycle described by sunspot areas
The temporal behavior of the sunspot cycles 12–22, as described by quarterly mean values of sunspot areas, can be represented by a single function containing only two parameters: the starting time and the amplitude of a cycle. The parameters are determined for the more recent 11 sunspot cycles and examined for any predictable behavior. As a sunspot cycle progresses, the amplitude parameter can ...
متن کاملWhy Does Consumption Lead the Business Cycle?¤
Consumption in the US leads output at the business cycle frequency. Standard RBC models predict the opposite. We show in this paper that the lack of an endogenous propagation mechanism that can support demand shocks is responsible for the discrepancy between RBC theory and data. ¤I thank two anonymous referees and the editor Harald Uhlig for helpful comments on an earlier version of the paper.
متن کاملWhy does the central nervous system not regenerate after injury?
A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...
