The convective weather processes in the atmosphere involve heating the air at the surface, lifting it from the Earth’s surface upwards. As the warm air rises, the water vapor condenses into water or ice. This convective process generates clouds and, ultimately, thunderstorms.
Not all clouds produce thunderstorms; fairly few do so. You can spot clouds that indicate a thunderstorm may develop, is developing, or has developed just by looking at their general appearance. They look like cauliflower.
Seriously, just like that. Looks familiar?
Now, let us look at how and why convection and thunderstorms form.
Convective weather
Before we go into detail, we need to take a few steps back and look at the big picture. To understand thunderstorms, we first must explore the underlying physical phenomena. These are phenomena you encounter daily, often without even realizing it.
You are undoubtedly familiar with most of them, and in this introduction, we will see how they influence the weather and thunderstorms. So before we talk about thunderstorms, we will talk about the environment they form and live in – our atmosphere.
The following sections are more technical, introducing some physical processes and properties, but we will not delve into equations. Knowing it is very helpful for understanding how convective weather, clouds, and thunderstorms work.
