The application provides a local weather control method in a virtual environment, an electronic device and a storage medium. The method comprises the following steps: calculating a current position of a target local weather according to first data sent by a master server, wherein the first data comprises a starting time, a starting position, a moving direction and a moving speed of the target local weather; when the current position of the target local weather enters a target area and the target area meets an appearance condition of the target local weather, rendering the target local weather in the target area according to the moving direction and the moving speed. The rendering of the local weather has a directional change process, which can increase the visual feeling caused by the movement of the weather from far to near. Meanwhile, the master server only needs to send the first data to each slave server, so that the control of the rendering of the local weather can be realized, and the calculation amount and performance consumption of the master server can be effectively reduced.
