Short summary
Short summary
We present the impact of quasi-biennial oscillation (QBO) disruption events on diurnal tides over the low- and mid-latitude MLT region observed by a meteor radar chain. By using a global atmospheric model and reanalysis data, it is found that the stratospheric QBO winds can affect the mesospheric diurnal tides by modulating the subtropical ozone variability in the upper stratosphere and the interaction between tides and gravity waves in the mesosphere.

Short summary
This study extensively investigates the characteristics of Es layer intensity, spatial distribution, diurnal variation, seasonal patterns, and long-term trends over East Asia, employing over 60 years of observational data from 21 ionosonde stations across China and Japan. The study reveals that sporadic E layer intensity over East Asia significantly exceeds the global average, with its intensity core centered along the 30° N latitude line and attenuating toward both lower and higher latitudes.
This study extensively investigates the characteristics of Es layer intensity, spatial...
