Analytical studies to visualise the geomagnetic storm conditions over different locations in the USA: Part 1

Abstract

Geomagnetic storms may trigger various risk-prone atmospheric and oceanic phenomena which may impart serious health hazards to the inhabitants of the biosphere too. Accordingly, the A-index data obtained from the US Department of Commerce, NOAA, Space Weather Prediction Center, for the time period started from 1994 to 2013, are analysed statistically to visualise the geomagnetic conditions over Fredericksburg (38.2047°N, 77.3729°W), College (64.8742°N, 147.8597°W) and Estimated Planetary in USA. Percentage occurrence of six different geomagnetic conditions namely quiet, unsettled, active, minor storm, major storm and severe storm are estimated for 12 different months over these different locations. The obtained results describe the sensitivity of these locations for the occurrence of geo-magnetic storms. These fruitful information may be useful in communication, navigation, civil-aviation, medical-science etc. Finally, these results can be used to adopt precaution to save various precious electrical and electro-magnetic systems, from getting effected and destroyed due to these high energetic geomagnetic storms.
