Effects of Solar Active Regions on Meridional Flows
Michal Svanda, Alexander G. Kosovichev, Junwei Zhao
The aim of this paper is to extend our previous study of the solar-cycle variations of the meridional flows and to investigate their latitudinal and longitudinal structure in the s…
Large-scale horizontal flows in the solar photosphere III: Effects on filament destabilization
Th. Roudier, M. Svanda, N. Meunier +7
We study the influence of large-scale photospheric motions on the estabilization of an eruptive filament, observed on October 6, 7, and 8, 2004, as part of an international observi…
Large-scale horizontal flows in the solar photosphere II: Long-term behaviour and magnetic activity response
Michal Svanda, Mirek Klvana, Michal Sobotka +1
Recently, we have developed a method useful for mapping large-scale horizontal velocity fields in the solar photosphere. The method was developed, tuned and calibrated using the sy…
Large-scale horizontal flows in the solar photosphere I: Method and tests on synthetic data
M. Svanda, M. Klvana, M. Sobotka
We propose a useful method for mapping large-scale velocity fields in the solar photosphere. It is based on the local correlation tracking algorithm when tracing supergranules in f…
