[Tex/LaTex] Citing the papers from the same author, but in different years are not in order

bibtexnatbib

Citing the papers from the same author but in different years are not arranged in the order in the list of reference.

Here is the bib file entry: 

@article{Patel2015AAQR,  
author = {Patel, P.N. and Kumar, R.},  
doi = {10.4209/aaqr.2015.02.0077},  
issn = {20711409 16808584},  
journal = {Aerosol Air Qual. Res.},  
keywords = {Dust storm,MODIS,Radiative forcing,Volume size distribution},  
number = {5},  
pages = {2082--2093},  
title = {{Estimation of aerosol characteristics and radiative forcing during dust events over Dehradun}},  
volume = {15},  
year = {2015}  
}  

@article{Patel2016AAQR,  
author = {Patel, Piyushkumar N. and Kumar, Raj},  
doi = {10.4209/aaqr.2015.05.0325},  
issn = {16808584},  
journal = {Aerosol Air Qual. Res.},  
keywords = {Aerosol indirect effect,Cloud radiative forcing,Dust,Ice cloud},  
number = {8},  
pages = {1820--1831},  
title = {{Dust Induced Changes in Ice Cloud and Cloud Radiative Forcing over a High Altitude Site}},  
url = {PAtel2016AAQR},  
volume = {16},  
year = {2016}  
}

It is citing like (Patel and Kumar 2015, 2016).

References:

Patel, P. N., and Kumar, R. (2016). Dust Induced Changes in Ice Cloud and Cloud Radiative Forcing over a High Altitude Site. Aerosol Air Qual. Res., 16(8):1820–1831.

Patel, P., and Kumar, R. (2015). Estimation of aerosol characteristics and radiative forcing during dust events over Dehradun. Aerosol Air Qual. Res., 15(5):2082–2093.

This arranged a list by alphabetically but for the case of the same author is not appear as per published year. I am using natbib with apalike style. Plese, help me in this.

Thank you

Here's an educated guess: The three publications -- each with three or more authors, right? -- share the same first author; however, it is also the case that the remaining authors are not all the same. The apalike bibliography style is programmed to sort the bibliographic entries first by the surnames of all authors, and not just by the surname of the author listed first, and only then by the year of the publication. Maybe something like this:

@misc{p:15,author="P. Piyush and A and D",year=2015}
@misc{p:16,author="P. Piyush and A and C",year=2016}
@misc{p:17,author="P. Piyush and A and B",year=2017}

Observe that the author fields differ only in the "names" of the third-listed authors. The apalike bibliography style will list the p:17 entry first, and p:15 last, since "B" precedes "C" which, in turn, precedes "D".

If you want the bibliographic entries sorted only by the surnames of the first-listed authors, you should switch to a bibliography style, specifically, to one that is programmed to do indeed sort only by the surnames of the first-listed authors. I suggest you look into using the plainnat bibliography style.

\begin{filecontents}{mybib.bib}

@misc{p:17,author="P. Piyush and A and B",year=2017}
\end{filecontents}

\bibliography{mybib}
\end{document}

Addendum: In the meantime, the OP has posted two actual entries from the bib file. Unfortunately, the two particular entries do not actually give rise to the issue the OP says he/she wishes to fix, as the following code demonstrates:
