Overview

Comparative analysis investigates ionospheric responses to ultra-fast Kelvin waves in the equatorial mesosphere, revealing distinct patterns.

Key Points

  • This research aims to analyze how ultra-fast Kelvin waves affect ionospheric total electron content and equatorial electrojet signatures.
  • Utilized zonal wind data and EEJ measurements
  • Analyzed global total electron content maps
  • Applied least squares spectral fitting to quantify periodic components
  • Identified three types of UFKW events based on their ionospheric responses
  • E2 and E3 waves exhibit significant seasonality, unlike E1 waves
  • E1 waves show a higher occurrence rate of ionospheric responses compared to E2 and E3 waves
