Abstract

The variations of the Earth’s magnetic field in the period 2013–2023 are considered based on the analysis of data from the INTERMAGNET network of observatories located in the South Pacific Ocean. It is shown that the 2015 El Niño was accompanied by anomalous geomagnetic variations with an amplitude of up to 120 nT with a pronounced increase in their standard deviation by 1.5 times relative to the average values of 2013. It is noted that starting from the end of 2022 – beginning of 2023, a sharp increase in geomagnetic field variations and an increase in their standard deviation (relative to 2021 by 2.5 times), which may indicate the beginning of the activation of a strong El Niño, the maximum intensity of which should be expected in 2024.
