How do thunderstorms start?

Answer 1

Thunderstorms start usually along a frontal boundary usually assoicated with a cold front but sometimes can happen with the other types of fronts. Along a cold frontal boundary, warm moist air is lifted up and over the cold air mass sitting behind the front. The warm moist air being uplifted along the frontal boundary cools by expansion and the moisture is condensed into clouds. Now here is where the fun part begins, the warm moist air that was uplifted along the cold frontal boundary is uplifted by updraft winds that continue expansional cooling and condensation upwards vertically. Usually before you see the thunderstorm mature you will start to see fair weather cumulus clump together into whats called cumulus congestus. Cumulus congestus are MASH potato shaped heaps of cumulus clouds that are coming together and are getting shot upwards in vertical motion by updraft winds. When a thunderstorm reaches maturity, it reaches the upper troposphere and the top of the thunderstorm cloud is ripped apart by the upper level jetstream into anvil cirrus clouds which are then carried downstream of the storm by the upper level jetstream. Before a thunderstorm matures, downdraft winds form in the front of the storm carrying precipitation and sometimes downbursts out of the storm. Once a thunderstorm runs out of moisture and energy, it starts to dissipate and weaken and eventually dies out all together.

Answer 2

First there needs to be some atmospheric instability, so a layer of warmer air above a layer of colder air. Then there needs to be humidity to fuel the rapid cloud formation. Also there needs to be vertical wind shear, meaning air moving in different directions and speeds at different heights, this contributes to the intensity of the storm. Finally you need a trigger to start convection, this can be air lifting of some type whether it be surface heating (not as likely) or frontal or orographic lifting (more likely).

Answer 3

lightning is a form of energy. it forms when the negative charges in the cloud get big enough and then finds a way to the ground. the thunder is auctually the sound of the lightnng. as humans see before hear, we see the lightning before we can hear its sound.

Answer 4

Thunderstorms are caused by the rapid upward movement of warm, moist air that cools and condenses to form cumulonimbus clouds. As the air rises, it releases latent heat, which fuels the storm's development. Lightning occurs when positive and negative charges build up in the cloud, creating electrical discharges.

Answer 5

Thunderstorms start by 2 temperatures fighting and then it starts to get windy then next thing you know you see rays of lighting.

Answer 6

As in what atmosphere does the thunderstorm land on? If That ... the answer is.. Troposphere.
