The Magnetic Storm of May 13–17

Crj80284 1311..1317

Genetic variation available for the improvement of fiber properties is restricted in commercial upland cotton (Gossypium hirsutum L.). Resources for fiber improvement exist in G. barbadense L., but introgression of traits has been a limited success. The objectives of this study were to investigate the genetic variation and heritability of agronomic and fiber traits within a diverse recombinant ...

Storm enhanced density: magnetic conjugacy effects

In the early phases of a geomagnetic storm, the low and mid-latitude ionosphere are greatly perturbed. Large SAPS electric fields map earthward from the perturbed ring current overlapping and eroding the outer plasmasphere and mid-latitude ionosphere, drawing out extended plumes of storm enhanced density (SED). We use combined satellite and ground-based observations to investigate the degree of...

Prediction of magnetic storm events using the Dst index

This paper provides a method to predict magnetic storm events based on the time series of the Dst index over the period 1981–2002. This method is based on the multiple scaling of the measure representation of the Dst time series. This measure is modeled as a recurrent iterated function system, which leads to a method to predict storm patterns included in its attractor. Numerical results are pro...

Magnetic Storm Effects in the Atmospheric Electric Field Variations

The vertical component (Ez) of the atmospheric electric field variations, measured at middle (obs. Swider) and polar (obs. Hornsund) latitudes under “fair-weather” conditions, have been analyzed. The strong effect of sharp daytime Ez increasing (negative Ez anomalies) in the middle latitudes was found during the main phase of the strong and moderate magnetic storms. The negative Ez deviation st...
