| Abstract | This study refers to the connection between the stratosphere and ionosphere, investigating, specifically, the behavior of the equatorial ionization anomaly (EIA) and ionospheric effects over the Brazilian region during sudden stratospheric warming (SSW) events that occurred in northern hemisphere winter (2005-2006 and 2008-2009) and a stratospheric warming period that occurred in the southern hemisphere winter in 2010, when, in both cases, the solar activity was low. During SSW events, through mechanisms not yet well known, planetary waves can be amplified and cause disturbances in the upper atmosphere winds. As it is already known, the winds are responsible for the dynamo mechanism which generates the ionospheric electric fields. These fields, in turn, are fundamental in the formation of the EIA. In this study the ionospheric behavior was investigated using a parameter ??, which express the EIA relative intensity for the Brazilian sector. This parameter is calculated from the ionospheric F2 layer critical frequency relative variation, which is obtained from Digisondes installed nearby the geomagnetic equator, São Luís (2.6° S, 44.2° W) or Fortaleza (3.8° S, 38° W) and near the EIA southern crest, Cachoeira Paulista (22.5° S, 45° W). The results for the Brazilian region show, mainly after SSW temperature peak, an increase in the EIA intensity in the morning, followed by a decrease in the afternoon. This behavior is preserved for a number of days equal to the polar region thermal stabilization phase and it is very similar to the results obtained in pioneering studies in the Peruvian sector, in which TEC data was used. In the Brazilian case, the negative variation is stronger than the positive, being noticeably more intense around the pre-reversal enhancement time, when the EIA is strongly suppressed. | |||
