Thus thunderstorms are more likely in the spring and summer than in the fall and winter. The sun warms the ground, which warms the air near the ground. In spring the air aloft retains its winter cold and thus will be more unstable than in the fall when the air aloft retains its summer warmth.

What are the 4 types of thunderstorms?

Why do thunderstorms happen at night?
Thunderstorms that form at night occur in the absence of heating at the ground by the sun. Consequently, the storms that form at night are usually “elevated,” meaning that they form aloft above the cooler air near the ground, rather than near the ground, which only during the day can get warmer.
Why is UK weather bad?
And, like much of Welsh weather, the reason behind the unsettled weather is all because of what’s happening with the jet stream over the Atlantic. … And that basically means the cold and wet weather gets “stuck” – rather than move west to east like it usually does.
Why is UK so warm?
Much of the UK’s hot weather comes from the jet stream, which is a narrow band of high speed winds. On either side of this, there will be slower warm and cool winds.
How frequent are thunderstorms in UK?

Why do thunderstorms most often occur in the summer months?
When warm moist air is unstable, it rises and expands. … Thunderstorm development is so common on summer afternoons because of this intense daytime heating as well as the high humidity, thus providing the moisture, the instability, and the warm temperatures needed to cause the air to begin rising.
