Solar quasi-biennial oscillations (QBOs) with the time scale of 0.6–4 yrs appear to be a basic
feature of the Sun's activity. Observational aspects of QBOs are reviewed on the basis of …

The relationship between solar magnetic activity and solar wind parameters, with observed
time-delayed mutual coupling, is an outstanding challenge in space physics. In this study …

Quasi-biennial oscillation (QBO) of solar magnetic activities is intrinsic to dynamo
mechanism, but still far from fully understood. In this work, the phase and amplitude …

Quasi-biennial oscillations (QBO) of solar activity (T≈ 1–4 years) are considered to be a
variation of basic solar activity, associated with the solar dynamo process. They are …

We identify large sunspot nestlets (SN) mostly containing recurrent sunspot groups and
investigate the indices of solar activity defined as the 11-or 22-year moving average of the …

Quasi-biennial oscillation (QBO) is a well-known variation in solar activity, interplanetary
parameters, geomagnetic disturbances and cosmic rays. Solar QBO is translated to the …

Magnetic field generation and evolution models that are capable of describing a large body
of observational material are currently available for different celestial bodies. Despite recent …

It is commonly accepted that the magnetic field of the Sun and other stars is generated
through the operation of the dynamo mechanism which is based on taking into account the …

Abstract Quasi-biennial Oscillations (QBOs) of the Sun have a significant meaning as a
benchmark of solar cycle, not only for understanding the dynamo action but also in terms of …

The cycles of solar magnetic activity are connected with a solar dynamo that operates in the
convective zone. Solar dynamo mechanism is based on the combined action of the …
