Fig. 5From: On the genesis of multi-peak vertical structure of quasi-two-day waves in the mesosphere–lower thermospherea Mean vertical profile of zonal mean zonal wind, averaged over the latitude band between 50° S and 20° S, for the selected years. Positive values indicate eastward winds and negative values indicate westward winds. b Latitude–altitude variations of temperature in the MLT region in the month of January, from the selected years, using SABER measurements c Black curve is same as that in Fig. 3c, which depicts the mean vertical profile of W3 amplitude and blue curve shows the vertical profile of meridional gradient of temperature averaged over the latitude band 50° S–20° S in January in the selected years. Horizontal bars represent corresponding standard errorsBack to article page
