abstract = "The High-Intensity Long-Duration and Continuous AE Activities
(HILDCAA) intervals are capable of causing a global disturbance in
the terrestrial ionosphere. However, the ionospheric storms
behavior due to these geomagnetic activity forms is still not
widely understood. In this study, we seek to comprise the HILDCAAs
disturbance time effects in the Total Electron Content (TEC)
values with respect to the quiet days' pattern analyzing local
time and seasonal dependences, and the influences of the solar
wind velocity to a sample of ten intervals occurred in 2015 and
2016 years. The main results showed that the hourly distribution
of the disturbance TEC may vary substantially between one interval
and another. Doing a comparative to geomagnetic storms, while the
positive ionospheric storms are more pronounced in the winter,
this season presents less geoeffectiveness or almost none to
HILDCAA intervals. It was find an equinoctial anomaly, since the
equinoxes represent more ionospheric TEC responses during HILDCAA
intervals than the solstices. Regarding to the solar wind
velocities, although HILDCAA intervals are associated to High
Speed Streams, this association does not present a direct relation
regards to TEC disturbances in low and equatorial latitudes.",
