This requires a strong instability of air distribution, which can occur, 30_______, when two fronts collide — warm and cold. 31_______, water vapor gradually rises, expands, cools and condenses. At the same time, part of the water droplets freezes, and part remains liquid. These types of droplets have a different electrical charge. The cloud grows, and with it the number of droplets and ice floes that carry electricity.   In winter, the air contains significantly fewer water molecules that have not turned into drops and snowflakes. This means that winter air masses contain less energy that could form a thundercloud 32_______ condensation, crystallization and powerful air circulation. 33_______, drops, ice flakes and snowflakes are less often charged against each other.   34_______, winter thunderstorms are quite real. When a powerful warm and humid air mass comes to us from the surface of warmer oceans and seas, intense convection can begin, sufficient to form a thundercloud. In such conditions, winter thunderstorms occur in central Russia, accompanied by snowfall. Moist fast sea air rises along the slopes and cools. At this time, condensation occurs and clouds form, which do not always turn into thunderstorms. 35_______, often the tops of mountains, for example, Elbrus or Dombay, are hidden under the clouds even in good weather. But for the formation of a cumulonimbus cloud, the air mass must have a large supply of moisture and an initial speed of movement. 36_______, practically everywhere on Earth there are still many more thunderstorms in summer, but winter thunderstorms still occur."
