The truth about solar container internal circulation

What is solar meridional circulation?

Solar meridional circulation is an axisymmetric flow system, extending from the equator to the poles (\ (\sim \) 20 m/s at the surface, \ (\approx \) 1% of the mean solar rotation rate), plunging inwards and subsequently completing the circuit in the interior through an equatorward return flow and a radially outward flow back up to the surface.

How can we learn about the solar dynamo?

By measuring the interior properties of different stars that result in a variety of stellar dynamos, we can place our knowledge of the solar dynamo into a broader context. By modeling the effects of rapid rotation on stellar structure, we can learn about the forces that shaped our own star in the past.

How does a heterogeneous wicking bilayer affect water circulation?

Combined with experimental, theoretical, and simulative results, it is concluded that the slight fluctuations in ambient temperature and the designed heterogeneous wicking bilayer enable the continuous evaporation and capillary flow inside the hermetic cell, forming water circulation process.

How is the water circulation process modeled in the HHC?

Sunlight was provided with a solar simulator (Enlitech, SS-X100R). COMSOL Multiphysics 6.1 was employed to model the water circulation process in the HHC with numerical methods. With realistic modeling, the conditions of temperature increasing, decreasing and fluctuations were stimulated to cover all situations.

How do solar dynamo shifts affect pulsation conditions?

These shifts can provide independent constraints on the physical mechanisms that drive the solar dynamo, through their influence on the outer boundary condition for the pulsation modes.

How does a strong solar cycle affect a satellite?

Strong solar cycles can negatively impact many industries, such as power transmission and satellite communications. Strong cycles expand the upper atmosphere, increasing the drag on all orbiting satellites. Historically, solar cycle predictions have been based on statistical methods, extrapolating from past behavior of the sun.
