Wind flow is one of the biosphere components that could change the amount of predation. This paper suggests and analyses a prey-predator model including wind in the predation task. The Holling-Tanner functional response has been considered to illustrate the global dynamics of the proposed model, considering the change in wind intensity. The persistence conditions are provided to reveal a threshold that will allow the coexistence of all species. Numerical simulations are provided to back up the theoretical analysis. The system’s coexistence can be achieved in abundance as long as the wind flow increases.
