Abstract: A-index data (from 1994 to 2013) obtained from Space Weather Prediction Center, NOAA, USA, are analysed statistically to visualise the variation in geomagnetic conditions over Fredericksburg (38.2047°N, 77.3729°W), College (64.8742°N, 147.8597°W) and Estimated Planetary in the USA. Year-to-year changes in percentage occurrence of different kind of geomagnetic storms have most prominently reflected over college, followed with estimated planetary. Fredericksburg has been accounted for least year-to-year changes in the percentage occurrence of different geomagnetic storm conditions during a month. Estimation of standard deviation quantify further the degree of year-to-year variability. These variations may be the key reason behind the drastic year-to-year changes in climatic conditions over the various region of this globe. These results may be proved useful in the areas of radio communication, civilaviation, navigation etc. It may also be helpful to incorporate essential measures while designing of electrical and electronics gadgets in order to save them from the severe effect of these storms.
