摘      要：The study of internal atmospheric waves,also known as gravity waves,which are detectable inside the fluid rather than at the fluid surface,is presented in this *** have used the time-fractional and fuzzy-fractional techniques to solve the differential equation system representing the atmospheric inter-nal waves *** q-Homotopy analysis Shehu transform technique(q-HAShTM)is used to solve the *** method helps find convergent solutions since it helps solve nonlinearity,and the fractional derivative can be easily computed using the Shehu ***,the obtained solution is compared for the particular case ofα=1 with the HAM solution to explain the method’s accuracy.
