A Study of the Characteristics of the Induced Geoelectric Field of Geomagnetic Storms in March 1989
Bibliographic record
Abstract
On March 13, 1989, the geomagnetic field disturbance (GMD) of an intense geomagnetic storm caused a power blackout in Canada. It is necessary to study whether the induced geoelectric field by similar GMD would have a serious impact on the low-latitude grid. In this paper, the GMD data of the geomagnetic storm on March 13,1989 at Beijing Geomagnetic Station are converted into digital data, and the magnetotelluric (MT) sounding data of the east of Mongolia are used to calculate the induced geoelectric field by the GMD using the plane wave theory. Characteristics of amplitude and variation of the induced geoelectric field by the geomagnetic storm on March 13, 1989 are studied. The results show that the geomagnetic storm on March 13, 1989 can produce the induced geoelectric field with the maximum value of 1.65 V / km in eastern Mongolia, and the maximum geoelectric field appears in the initial phase of the geomagnetic storm. This conclusion is of great significance to understand the harm of the geomagnetic storm.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
