Synopsis

Presentiamo i risultati dell'esperimento di riscaldamento ionosferico condotto presso l'impianto High Frequency Active Auroral Research Program (HAARP), in Alaska. Durante l'esperimento, HAARP ha trasmesso in direzione dell'onda magnetica zenitale X-mode 4,57-MHz. La potenza trasmessa � stata modulata con una frequenza di 0,9 mHz ed � stata puntata su uno spot di 20 km a 120 km di altitudine. Il riscaldamento (1) genera disturbi nel campo magnetico rilevati con il magnetometro fluxgate a terra e (2) produce punti luminosi nella ionosfera, osservati con il telescopio HAARP. Le simulazioni numeriche del modello magnetoidrodinamico (MHD) ridotto 3-D rivelano che questi effetti possono essere correlati alle correnti allineate al campo magnetico, eccitate nella ionosfera modificando la conduttivit� nella regione E quando esiste un campo elettrico su larga scala nella regione di riscaldamento.Variazioni improvvise della pressione dinamica del vento solare hanno un impatto significativo sulla dinamica del sistema magnetosfera-ionosfera; un'improvvisa diminuzione della pressione dinamica del vento solare � stata osservata dal satellite Wind, che ha influenzato l'intero sistema magnetosfera-ionosfera, come registrato in molti studi a terra e nello spazio.
