where the unknown functions u=u(x, t)=(u_{1}(x, t), u_{2}(x, t), u_{3}(x, t)) and p=p(x, t) denote the velocity field and the pressure of the fluid, respectively, while u_{0}=u_{0}(x)= (u_{0,1}(x), u_{0,2}(x), u_{0,3}(x)) denotes the given initial velocity field satisfying the compatibility condition divu0 =0 . Here $Omega$in mathbb{R} represents the speed of rotation around the vertical unit vector e_{3}=(0,0,1) , which is called the Coriolis parameter. The main purpose of this note is to prove the local existence and the uniqueness of a mild solution to (NSC). In particular, we are interested in the dispersive efect of the Coriolis force and consider how the speed of rotation | $Omega$| afects the size of the existence time T of solutions
