A Rohini sounding rocket carrying a Langmuir probe was flown from Thumba (8.3 degrees N, 76.9 degrees E), India on 27 November 2005 to study the winter equatorial mesospheric neutral turbulence from electron density measurements. The most important result of this study is the detection of a few thin intermittent turbulent layers of 100-200 m thickness, and this was possible due to the use of the continuous wavelet transform technique. This study shows that the winter turbulence is very weak. Also, the contribution of neutral turbulence process towards heating the mesosphere is significantly less during winter.
