This paper presents a 2D nonhydrostatic allelastic meso-γ-scale numerical modelto simulate the planetary boundary layer (PBL)with a moving heat island over the surface.In the experiments we took temperaure △θ_g=60K and 30K,separately,for the island movingat the same speed of 4m·s,leading to strong rising behind the island and a local circulation 3～5km wide for the case of 60K.The maximum rising of order of 80～100 cm·s was mea-sured at the height of 300～400m, In the case of 30K,however.the effects of the moving island on the PBL became greatly weakened as compared to the first case,with no closed localcirculation observed.
