Abstract: The brightness of the planet Jupiter is found to be related to mean annual and monthly relative sunspot numbers which are used to indicate the general level of solar activity. The evidence for the relationship is presented ...

Abstract: An improved amplitude restoring interpolation operator is specialized into a form that corrects the phase error as well as the amplitude damping introduced by two-point linear interpolation. The efficiency and accuracy of ...

Abstract: The persistence of the three-day mean surface pressure distribution in a mid-latitude region centered on the Greenwich meridian is examined in connection with large increases in geomagnetic activity and is compared with ...

Abstract: The solar magnetic sector structure has recently been reported to be related to the atmospheric absolute vorticity (Wilcox et al., 1973, 1974). An examination of some of the statistics of this association shows that it may ...

Abstract: A test of an apparent association between solar corpuscular radiation (measured by planetary-scale geomagnetic disturbance) and the subsequent behavior of the sea-level pressure distribution is carried out with completely ...

Abstract: Observations of the persistence of the surface pressure distribution are compared for two regions of the northern hemisphere. One region covers most of North America ; the other region is comparable in size and is centered ...
