Causes of Thunderstorms ~ Thunderstorms occur when warm, moist air within a rain cloud, rises in large volumes and with increasing velocity. That's five times hotter than the surface of the Sun! What causes thunder and lightning? As the warm air rises it cools and condenses forming small droplets of water. This giant spark of electricity surges through clouds and sometimes touches down on Earth’s surface. Also known as electrical storms, lightning storms, or thundershowers, thunderstorms are caused by an updraft that occurs when warm, moist air rises up into the atmosphere. ~ The velocity and volume of warm air within the cloud increases, initiating a warm updraft. Until now such … Then, the updraft forms a cumulus cloud, which eventually becomes the thunderstorm cloud. When the temperature difference is large, the risk of severe thunderstorms increases. This is when warm air exists underneath much colder air. Consequently, thunderstorms are usually followed by dense rain and cloudbursts.” The researchers conclude that the risk of major thunderstorms and cloudbursts is influenced by differences between the Earth’s surface temperature at night and during the day. Even though thunderstorms are common, they are still dramatic events with intense rain, hail, wind, lightning, thunder, and even tornadoes. The result is a long-lived supercell storm. The air then contracts rapidly as it cools. Causes and Effects of Thunderstorms: A thunderstorm caused when warm and moist air rises and swift updraft to colder regions of the atmosphere affecting the zone with its irresistible destruction, is an intense, short-lived weather disturbance. What causes thunder: Thunder is the sound lightning makes, this is because lightning suddenly increases the pressure and temperature around it, expanding the air and making a … What is a Thunderstorm? This makes the storm cloud more buoyant and it rises upwards. The warm air becomes cooler, which causes moisture, called water vapor, to form small water droplets - a process called condensation. What causes thunder? What causes lightning: When a positive and negative charge grows large enough in the sky you get lightning. A thunderstorm is basically a storm characterized by lightning and thunder. The heated air expands explosively, creating a shockwave as the surrounding air is rapidly compressed. These storms are the most intense type of thunderstorm. Thunderstorm - Thunderstorm - Supercell storms: When environmental winds are favourable, the updraft and downdraft of a storm become organized and twist around and reinforce each other. Aug. 29, 2016 — Violent thunderstorms can often cause torrential rain, which pose a threat for both humans and the infrastructure. Thunderstorms form when warm, moist air rises into cold air. Thunderstorms develop when the atmosphere is unstable. In a fraction of a second, lightning heats the air around it to incredible temperatures—as hot as 54,000 °F (30,000 °C).
