| Sumario: | Las propiedades del viento solar en el entorno terrestre son consecuencia de la actividad solar y de los procesos que ocurren durante la evolución del plasma interplanetario desde el Sol hasta 1 au, y son esenciales para determinar el nivel de acoplamiento Sol-Tierra. En este trabajo analizamos datos de plasma y campo magnético observados con instrumentos a bordo de la nave espacial ACE, durante el período 1998-2017. The properties of the solar wind at the terrestrial space environment are consequences of the solar activity and the processes that occur during the evolution of the interplanetary plasma from the Sun to 1 au and are important to determine the level of Sun-Earth coupling. In this work we analyze plasma and magnetic field data from the ACE spacecraft, during the period 1998-2017. We present an analysis of the relationship between different characteristics of the solar wind and the geoeffective events of solar origin, in order to generate operational tools that allow to identify such events. We focus the study on the behavior of interplanetary coronal mass ejections, identified in the Richardson and Cane catalog during the mentioned period, in relation to the temperature of the solar wind and the Parker spiral, at the Ll point. From this study, we define thresholds for the plasma temperature, the angle between the interplanetary magnetic field and the Sun-Earth line, and the angle between the interplanetary magnetic field and the ecliptic plane. Combining both criteria we expect to increase the probability of success in identifying these interplanetary structures. |
