The present invention provides an apparatus for weather modification. The apparatus comprises an emitter electrode (21), means for providing the emitter electrode (21) with an electric charge, electrically coupled to the emitter electrode (21), an insulating support for supporting the emitter electrode (21) at a predetermined height, and means for earthing the apparatus. The emitter electrode (21) comprises a Malter film. According to another aspect of the present invention an apparatus for weather modification is provided, which comprises a lighter-than-air craft suitable for carrying an emitter electrode (21), means for providing the emitter electrode (21) with an electric charge, electrically coupled to the emitter electrode (21), and means for earthing the apparatus. According to still a further aspect of the present invention, a method of increasing the amount of precipitation in a target region is provided. The method comprises the steps of providing an emitter electrode (21), analyzing the meteorological situation in and/or close to the target region, and providing the emitter electrode (21) with an electric charge in response to the meteorological analysis, thereby causing the emitter electrode (21) to ionize the vicinity of the emitter electrode.
