Propagation of gravity waves and spread F in the low-latitude ionosphere over Tucumán, Argentina, by continuous Doppler sounding: First results
Popis výsledku v původním jazyce
Results of systematic analysis of propagation directions and horizontal velocities of Gravity Waves (GWs) and spread F structures in low-latitude ionosphere (magnetic inclination 27 ) in Tucuman region, Argentina, are presented. Measurements were carriedout by multi-point continuous Doppler system during one year from December 2012 to November 2013. It was found that meridian propagation of GWs dominated, and that southward propagation prevailed in the local summer. Oblique spread structures observed in Doppler shift spectrograms and associated with spread F propagated roughly eastward at velocities from 70 to 180 m/s and were observed at night from September to March. The velocities were computed for 182 events, and the azimuths for 64 events. Continuous Doppler sounding makes it possible to analyze more events compared to optical observations often used for propagation studies since the measurements do not depend on weather.
