The tropical Pacific variability significantly affects the global weather and climate from annual to interdecadal timescales. The El Niño Southern–Oscillation (ENSO) in this region has a direct association with extreme weather precipitation and climate anomalies across the world. Many studies have been shown that the tropical Pacific has statistically significant responses to the solar...

Recent studies have revealed important advances in understanding how the direct effects of energetic electron precipitation (EEP) on mesospheric ozone influence atmospheric dynamics (Zúñiga López et al., 2022). These findings show that EEP can significantly affect mesospheric temperature, wave breaking and refraction, and consequently atmospheric winds and circulation. However, the magnitude...

Most predictions of space climate, that is, the long-term behavior of the solar-terrestrial environment, have focused on forecasting the 11-year sunspot cycle. Geomagnetic activity, on the other hand, has mainly been predicted in shorter, space weather timescales of up to days to weeks. Using a 180-year composite aa index, we aim to predict here the temporal behavior of geomagnetic activity...

Space climate affects not only the magnetosphere and ionosphere, but also the middle atmosphere, including the mesosphere (50–80 km) and stratosphere (15–50 km). Variations in solar radiation and precipitating energetic particles (EPP) influence atmospheric composition, particularly ozone, which plays a central role in the atmospheric radiative balance through its absorption of shortwave and...
