Continuum Moment Equations on the Lattice
An analysis is given as to why one can not directly evaluate continuum moment
equations, i.e., equations involving powers of the position variable times
charge, current, or energy/momentum operators, on the lattice. I examine two
cases: a three point function evaluation of the nucleon magnetic moment and a
four point function (charge overlap) evaluation of the pseudoscalar charge
radius.Comment: 9 pages; 1 ps figur
History of solar-terrestrial relations as deduced from spacecraft and geomagnetic data: Solar M regions
This brief history is organized around the long problem of the solar M region, i.e. the structure on the sun that is responsible for recurrent geomagnetic disturbances
Solar activity and the weather
The attempts during the past century to establish a connection between solar activity and the weather are discussed; some critical remarks about the quality of much of the literature in this field are given. Several recent investigations are summarized. Use of the solar/interplanetary magnetic sector structure in future investigations is suggested to add an element of cohesiveness and interaction to these investigations
Solar Wind Disturbances Associated with Flares
Solar wind disturbances associated with flare
A synoptic approach to sun-weather investigations
The advantages of a regular program of daily observations of the magnetosphere, ionosphere and atmosphere are described. Such synoptic observations may be one of the best routes to understanding the physical mechanisms involved in sun-weather influences. Some specific examples of such observations are given
Why does the sun sometimes look like a magnetic monopole?
For several months in early 1965 the sun appeared to have large scale magnetic field directed outwards at nearly all latitudes and longitudes. Several independent observations that lead to this puzzling situation are discussed
Solar structure and terrestrial weather
The possibility that solar activity has discernible effects on terrestrial weather is considered. Research involving correlation of weather conditions with solar and geomagnetic activity is discussed
Asymmetry in geomagnetic response to the polarity of the interplanetary magnetic field
Geomagnetic asymmetric response as function of polarity pattern of interplanetary magnetic fiel
Geophysical predications: Sun-weather
The present status of sun-weather research is summarized. Recommendations for future research are given
