| Zusammenfassung |
| We study the occurrence characteristics of mesospheric inversion layers
(MILs) in the 60–105 km altitude region over the low-latitude Indian sector. We
note that lower inversions in the mesospheric temperatures occur in the
70–75 km altitude regions while the upper inversions occur in 90–95 km
altitude regions. The mesopause altitude is mostly noted to be ~ 98 km
with the night-time mesopause (particularly in the year 2002) showing a small
peak in the mesopause occurrence at ~ 75 km altitude. We note higher
occurrence rate of MILs during high solar activity year compared to low
solar activity year. It is also observed that night time MILs show a
systematic seasonal variability, with higher occurrence of single and double
temperature inversions during equinoxes. |
