Rotational quasi periodicities and the Sun - heliosphere connection
J. K. Lawrence, A. C. Cadavid, A. Ruzmaikin
Mutual quasi-periodicities near the solar-rotation period appear in time series based on the Earth's magnetic field, the interplanetary magnetic field, and signed solar-magnetic fi…
Principal Components and Independent Component Analysis of Solar and Space Data
A. C. Cadavid, J. K. Lawrence, A. Ruzmaikin
Principal Components Analysis (PCA) and Independent Component Analysis (ICA) are used to identify global patterns in solar and space data. PCA seeks orthogonal modes of the two-poi…
Mesogranulation and Turbulence in Photospheric Flows
J. K. Lawrence, A. C. Cadavid, A. Ruzmaikin
Below the scale of supergranules we find that cellular flows are present in the solar photosphere at two distinct size scales, approximately 2 Mm and 4 Mm, with distinct characteri…
Spatio-Temporal Scaling of Solar Surface Flows
J. K. Lawrence, A. C. Cadavid, A. Ruzmaikin +1
The Sun provides an excellent natural laboratory for nonlinear phenomena. We use motions of magnetic bright points on the solar surface, at the smallest scales yet observed, to stu…
