Quasi-biennial and quasi-triennial oscillations in geomagnetic activity indices

Data for geomagnetic activity index aa for 1868±1994 were subjected to spectral analysis for 12 intervals each of 11 consecutive years. In each interval, QBO and QTO (quasi-biennial and quasi-triennial oscillations) were observed at 2:00, 2.15, 2.40, 2.70 y and 3:20, 3.40 y, but not all in all intervals. These ̄uctuations are absent near (2±3 y before and after) the sunspot minima and are presen...

Cardiac Arrhythmia and Geomagnetic Activity

BACKGROUND The purpose of this paper is a review of a number of studies considering links between life threatening cardiac arrhythmias, sudden cardiac death (SCD) and the level of environmental physical activity factors like geomagnetic activity (GMA) and opposite them cosmic ray and high energy proton flux. This is a part of studies in the field named Clinical Cosmobiology. METHODS Temporal ...

Modelling Geomagnetic Activity Data

Strong geomagnetic activity is a hazard to electronics and electric power facilities. Assessment of the actual geomagnetic activity level from local magnetometer monitoring therefore is of importance for risk assessment but also in earth sciences and exploration. Wavelet based signal processing methods are applied to extract meaningful information from magnetic field time series in a noisy envi...

Semiannual Variation of Geomagnetic Activity

The semiannual variation in geomagnetic activity is well established in geomagnetic data Its explanation has remained elusive, however. We propose, simply, that it is caused by a semiannual variation in the effective southward component of the interplanetary field. The southward field arises because the interplanetary field is ordered in the solar equatorial coordinate system, whereas the inter...

Predicting Geomagnetic Activity Index by Brain Emotional Learning

The Emotional Learning Algorithm has been introduced to show the effect of emotions as well known stimuli in the quick and almost satisficing decision making in human. The remarkable properties of emotional learning, low computational complexity and fast training, and its simplicity in multi objective problems has made it a powerful methodology in real time control and decision systems, where t...
