Review of “Magnetospheric Chaos and Dynamical Complexity Response During Storm time Disturbance” by Oludehinwa, Olusola, Bolaji, Odeyemi and Njah
The paper is interesting, contains new information and should be published in NPG after suitable corrections are made. The paper still has major omissions in background information and quite a few grammatical problems.
Title. The title of the paper indicates that the authors are addressing only magnetic storms. However since the authors are using broad swaths of data in their analyses they are also analyzing isolated substorms and HILDCAA intervals as well. These would most likely fall under the category of “minor storms”? I notice that in the revision they discuss “monthly storm intervals”? The authors need to discuss more thoroughly how they identify the intensity of these “monthly storms”. (As I have previously mentioned a further productive effort would be for the authors to study CIRs, sheaths, CMEs and HILDCAAs separately. Right now they are getting a mixture of all the above. This is difficult to interpret).
I suggest that the authors therefore include some discussion of isolated substorms (PSS, 12, 273-282, 1964) and HILDCAAs (PSS, 35, 4, 405-412, 1987; JGRSP, 118, 1-13, 2013. Doi:10.1002/jgra.50530) in the Introduction Section of the paper.
Introduction, line 27. The authors should list the paper that started all this discussion of magnetospheric complexity. It is GRL, 17, 3, 279-282, 1990. It will fit here.
Line 29. The authors should list the major paper concerning magnetospheric convection. This is PRL, 6, 47, 1961. This reference is far more important than the one you have here.
Line 33-34. The first CIR storm reference should be added here. It is PSS, 35, 4, 405-412, 1987. This also covers HILDCAAs.
Line 47. Drivers?
Line 50. Observational evidence should be given to VBs. I suggest JGR, 94, A7, 8835-8851, 1989 and JGR, 99, A4, 5771-5792, 1994. I also suggest moving the Russell and McPherron 1974 and Burton et al 1975 (lines 33 and 34) references to here. The latter two authors did not discuss sheaths, CIRs and MCs.
Lines 72-73. “plots”? “analyses”?
Line 75. As a non-autonomous
Line 78. “functions”?
Lines 83-84. Studied magnetospheric dynamics using AL indices with the southward components …
Line 89. To the fact that…
Line 97. At which the nonlinearity response
Line 102. Analyses
Line 105. There is no mention what section 4 contains. Please add that.
Line 110. See AG, 24, 2243-2276, 2006 and JGR, 110. A11214, 2005. doi:10.1029/2004JA010584, 2005. These papers discuss the physics between these different current layers and should be referenced.
Line 130. There should not be any commas after the author’s names.
Line 138. neighbor, respectively.
Line 142-3. instead of an autocorrelation
Line 149. “where” should not be capitalized since it is a continuation of the sentence following the equation.
Line 153. “versus” is a better word than “against”
Line 170. See line 149 comment about “Where”
Line 181. How about “change appreciably”?
Line 208. again see line 149.
Line 257. …yields a DV plot?
Line 334. An important reference here is pages 1-17, 2006 from the same book.
Line 335. This was originally shown in Gonzalez et al. 1994 and JGR, 100, A11, 21717-21733, 1995. These references should be added here.
Line 367, 368 and 372. Shouldn’t this be “storms”?
Line 380. The same as the above. Maybe also in many other places?

Short summary

The MLE and ApEn values of the D_st indicate that chaotic and dynamical complexity responses are high during minor geomagnetic storms, reduce at moderate geomagnetic storms and decline further during major geomagnetic storms. However, the MLE and ApEn values obtained from solar wind electric field (VB_s) indicate that chaotic and dynamical complexity responses are high with no significant difference between the periods that are associated with minor, moderate and major geomagnetic storms.
