FUNCTIONAL SUNSPOT EQUILIBRIA [PDF]
Consider a one step forward looking model where agents believe that the equilibrium values of the state variable are determined by a function whose domain is the current value of the state variable and whose range is the value for the subsequent period ...

Prediction of even and odd sunspot cycles [PDF]
Here we study the prediction of even and odd numbered sunspot cycles separately, thereby taking into account the Hale cyclicity of solar magnetism. We first show that the temporal evolution and shape of all sunspot cycles are extremely well-described by ...

This paper shows new properties about the equilibria of a stationary OG economy by establishing a connection between its stationary equilibria and those of a finite economy, with and without extrinsic uncertainty.

The 5 minute oscillations in a sunspot umbra are the response of the sunspot to forcing by the 5 minute p-modes in the surrounding convection zone (Thomas 1981). This interaction of solar p-modes with a sunspot can be used to probe the structure of a sunspot beneath the visible surface of the Sun (Thomas, Cram, and Nye 1982). Here we report briefly the

Von Lindener's sunspot data: sunspot group number and individual sunspot number
Hayakawa et al. (2023) derived sunspot group number and individual sunspot number from von Liindener's records. These data have been extracted from von Lindener's manuscript (Akc.1985/15) in the Library of Wrocław University and Bode (1819).

Sunspot Number Prediction Using Gated Recurrent Unit (GRU) Algorithm
Sunspot is an area on photosphere layer which is dark-colored. Sunspot is very important to be researched because sunspot is affected by sunspot numbers, which present the level of solar activity. This research was conducted to make prediction on sunspot

Study of the effect of sunspots on seasonal and annual precipitation through wavelet analysis: A case study of the stations in Isfahan and Kashan [PDF]
Introduction: The sun is the main source of Earth energy and its climate changes. Changes in the amount of energy emitted from the sun or in its surface temperature can cause fluctuations in the atmosphere.
