In this work we studied the regional manifestations of space weather at central Mexico through isolate the local geomagnetic response from its planetary counterpart. In order to do so, we analyzed 20 intense geomagnetic storms by identifying the ionospheric contribution in their regional geomagnetic data as registered at the Magnetic Observatory of Teoloyucan (located at the north of Mexico City). Our analysis indicated that local geomagnetic response is mainly driven by ionospheric disturbances. We also found that the disturbed polar current number 2 and the disturbed dynamo current are particularly relevant for the regional geomagnetic response. Additionally, we showed that regional geomagnetic activity can be approximated by the combined effects of the planetary geomagnetic response and the regional magnetic perturbations induced by the commented ionospheric currents. Finally, our results highlights the particularities that geomagnetic response has at regional scales.
