<p><b>Abstract:</b>
<br>
The striking similarity between the statistics of plasma density fluctuations in the TORPEX device [B. Labit et al., Phys. Rev. Lett. 98, 255002 (2007)] and sea-surface temperature fluctuations [Po Sura and P. D. Sardeshmukh, J. Phys. Oceanogr. 38, 638 (2007)] (SS) is discussed. A nonlinear Langevin theory due to SS is generalized to include linear wave propagation. An interpretation of the nonlinear Langevin equation based on statistical closure theory is proposed.
