Fig. 5.From: First observational study during a solar eclipse event on variations in the horizontal winds simultaneously in the troposphere-stratosphere-mesosphere-lower-thermosphere region over the equatorial station Thumba (8.5°N, 77°E)The vertical wavelength spectra of zonal winds (upper panel), and meridional winds (lower panels), observed during 12:30–13:30 hrs (left panels) and 14:30–15:30 hrs (right panels) in the (a) troposphere, and (b) stratosphere, for the control day (blue) and the eclipse day (red). The horizontal lines in all the plots indicate the 95% significance level.Back to article page
