Prediction of Magnetic Storms by Nonlinear
The strong correlation between magnetic storms and southward interplanetary magnetic eld (IMF) is well known from linear prediction lter studies using the Dst and IMF data. However, the linear lters change signiicantly from one storm to another and thus are limited in their predicting ability. Previous studies have indicated nonlinearity in the magneto-spheric response as the ring current decay...
متن کاملThe Electric Current-systems of Magnetic Storms
1. This paper continues my discussion of the average characteristics of the field of geomagnetic disturbances or storms, given in two previous papers • which will be referred to as I and 2; the irregular part of magnetic disturbance is not considered. A condensed representation of the main average features of magnetic storms is given in 1 (pp. 61-72) and 2 (pp. 242-264), and evidence is describ...
متن کاملThe size of the auroral belt during magnetic storms
Using the auroral boundary index derived from DMSP electron precipitation data and the Dst index, changes in the size of the auroral belt during magnetic storms are studied. It is found that the equatorward boundary of the belt at midnight expands equatorward, reaching its lowest latitude about one hour before Dst peaks. This time lag depends very little on storm intensity. It is also shown tha...
متن کاملSevere Local Storms
Knowledge of severe local storms has been increasing rapidly in recent years as a result of both observational studies and numerical modeling experiments. This paper reviews that knowledge as it relates to development of new applications for forecasting of severe local storms. Many of these new applications are based on physical understanding of processes taking place on the storm scale and thu...
