In a typical thundercloud, the upper part, made of ice crystals, is generally positively charged, while the lower part, made of water droplets, is negatively charged. By influence, the lower part of the cloud leads to the development of charges of opposite signs (therefore positive on the part of the ground which is nearby). Electrical exchanges occur inside this cloud, but also between different clouds of the same nature. We then see lightning. However, the cumulonimbus also behaves like a gigantic cloud-to-ground plane capacitor.
