Multiple-scale Temporal Variability of Climatic Time Series in the Western Region of Iran [PDF]
Sustainable Earth Trends, 2023 The current research aims to carry out a multi-timescale variability analysis for the time series of sunspots (SN), precipitation (Pr), and maximum temperature (Tmax) in four main stations in the western area of Iran.

Sensors, 2021 Strong flares and coronal mass ejections (CMEs), launched from δ-sunspots, are the most catastrophic energy-releasing events in the solar system. The formations of δ-sunspots and relevant polarity inversion lines (PILs) are crucial for the understanding ...

Evolutions of various solar indices around sunspot maximum and sunspot minimum years [PDF]
Annales Geophysicae, 2002 The smoothed monthly sunspot numbers showed that in many solar cycles, (a) during years around sunspot maxima, there was only one prominent maximum, but in some cycles there was a broad plateau. If the beginning and end of these are termed as first

SUNSPOTS AND CREDIT FRICTIONS [PDF]
Macroeconomic Dynamics, 2012 We examine a general equilibrium model with collateral constraints and increasing returns to scale in production. The utility function is nonseparable, with no income effect on the consumer's choice of leisure. Unlike this model without a collateral constraint, we find that indeterminacy of equilibria is possible.

The transition region above sunspots
Geoscience Letters, 2018 Over decades, sunspots and their fine structures have been studied in detail at the photospheric level with different ground-based telescopes, as the surface of the Sun primarily emits light in the visible wavelengths.

Identification of beryllium hydride isotopomer lines in sunspot umbral spectra [PDF]
Serbian Astronomical Journal, 2008 A high resolution spectrum of FTS sunspot umbra of NSO/Kitt Peak was used to conduct a search for the molecular absorption lines due to BeH, BeD and BeT isotopomers. Analysis led to estimates of identification of the molecular lines of bands A - X (0,0),
