Fine structure in sunspots III. Penumbral grains
The properties of penumbral grains (PGs) in a medium-size sunspot are studied from a 4.5 hour observation series acquired on 5 June 1993 at the Swedish Vacuum Solar Telescope, La Palma. The application of an image segmentation procedure and a feature tracking algorithm on a movie of 360 frames yields proper motions, intensities, and lifetimes for a set of 469 PGs. Almost 3/4 of the PGs move tow...
متن کاملChanges in the Pattern of Distribution of Southwest Monsoon Rainfall Over India Associated With Sunspots
Despite the systematic nature of the monsoon rains over India, large year-to-year variations in the pattern of distribution of rainfall during the season occur. The yearly pattern of rainfall distribution during the monsoon season (May 31-October 2) for each of the years 1901-51 for a network of 105 stations over India is characterized by a set of six distribution parameters. A brief descriptio...
متن کاملSunspots and Temperatures
Power spectrum analyses of temperature series at New York City (1822-1956), the Netherlands (1735-1944), and central England (1698-1955) show that the only significant energy in these spectrums appears at the annual period of 12 months. No significant energy was found corresponding to any known sunspot periodicity. Correlation coefficients between January and July temperatures for the years of ...
متن کاملSunspots, correlation and competition
Correlated equilibria in strategic market games played, simultaneously, by “overlapping generations” of players correspond to sunspot equilibria in the associated, competitive economy. The lower the degree of competition, the larger the range of parameters that allow for effective correlation or endogenous stochastic fluctuations.
متن کاملImperfect Competition and Sunspots
This paper shows that imperfect competition can be a rich source of sunspots equilibria and coordination failures. This is demonstrated in a dynamic general equilibrium model that has no major distortions except imperfect competition. In the absence of fundamental shocks, the model has a unique certainty (fundamental) equilibrium. But there is also a continuum of stochastic (sunspots) equilibri...
