As a consequence of thesimilarity amongst measurements and simulations, the latter is used to diagnose this heretofore unexplainedphenomenon. The simulation reveals which the EIA‐X can occur during geomagnetically peaceful situations and inthe afternoon to night sector at a longitude exactly where the vertical drift is downward. The downward vertical driftis a required but not ample situation. The simulation was executed underneath consistent minimal‐photo voltaic andquiescent‐geomagnetic forcing problems, thus we conclude that EIA‐X could be pushed by reduce‐atmospheric forcing.
