\(\begin{array}{l}
{\rm{EL}}{{\rm{R}}_1} = \frac{{{\rm{\Delta T}}}}{{{\rm{\Delta h}}}} = \frac{{15.5 - 15.0}}{{60 - 10}} = 0.01^\circ \frac{{\rm{c}}}{{\rm{m}}} = \;10^\circ \frac{{\rm{c}}}{{{\rm{km}}}}\;\\
{\rm{EL}}{{\rm{R}}_2} = \frac{{15.0 - 14.3}}{{130 - 60}} = 0.01^\circ \frac{{\rm{C}}}{{\rm{m}}} = \;10^\circ \frac{{\rm{c}}}{{{\rm{km}}}}
\end{array}\)
Adiabatic lapse rate (ALR) is 9.8°C/km for dry adiabatic and 6.c/km for wet adiabatic condition.
∵ ELR > ALR
So, it is super adiabatic and the atmosphere is said to be highly unstable.
