In this paper, we study the equation in the domain , where is the free boundary and . The influence of the advection coefficient on the propagation dynamics of the solutions is considered. We find two parameters 2 and such that when , only spreading happens; when , there is a virtual spreading-transition-vanishing trichotomy result; when , only vanishing happens.
