Severe Thunderstorms. Rising ground forcing the air upwards (orographic uplift). The warm, moist air immediately above the ground is less dense than the cooler, … The air must be warm and moist. Thundersnow usually forms when layers of flat snow clouds develop instability and experience dynamic lifting. How a thunderstorm forms Next. As the air rises, it cools and the moisture condenses, falling back to Earth as precipitation. When a thunderstorm begins to form, it does so at the cumulus stage. Stage 2: The warm air meets very cold air in the middle levels of the atmosphere. All thunderstorms start with moisture and rising warm air. Thunderstorms can form in winter, but they have different characteristics. The sun heats the surface of the earth, which warms the air above it. This typically occurs on a warm summer’s day when the longer hours of sunshine have heated the ground. Some of the most violent aspects of thunderstorms … From there, it advances in activity until it reaches its peak at the mature stage. Cells continue to form within the clouds as the multicell storm regenerates itself. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A typical normal thunderstorm consists of tall, narrow clouds that rise from a warm updraft leading from the surface up to around 40,000 feet. This diagram sequence shows the stages in the development of a thunderstorm: Stage 1: Warm moist air is forced upwards, forming a cumulus cloud. If this warm surface air is forced to rise -- … Cumulonimbus (Cb) (Cb) clouds, in which Thunderstorms are found, form when three conditions are met: There must be a deep layer of unstable air. Thunderstorms form and die out within the storm. Start studying How does a thunderstorm form?. Storms are fueled by heat and moisture, which is why storm activity, particularly thunderstorm activity, is greater during the summer season. Storms form when warm, moisture-laden air rises rapidly into the atmosphere. A total of thirty or more cells may develop during the lifetime of a storm. A trigger mechanism must cause the warm moist air to rise: Heating of the layer of air close to the surface. Three basic ingredients are required for a thunderstorm to form: moisture, rising unstable air (air that keeps rising when given a nudge), and a lifting mechanism to provide the "nudge." And moisture, which is why storm activity, is greater during the lifetime of storm.
