Oh, wow, oh, oh, oh, wow, oh, oh, wow.

Oh, wow.

Oh, wow. Hello, you're listening to The Science of Everything podcast, episode 109, weather part one.

I'm your host, James Fodor.

So in this episode, we're going to start a hopefully two-part series looking at the weather.

And as sort of preparatory to that, in this episode we're going to be talking about basic concepts

that are important to understanding the weather,

including humidity, atmospheric stability of air parcels.

We'll talk about cloud formation and different types of clouds and precipitation and also look at air masses.

This will lead up into the next episode when we talk about different types of storms and weather patterns,

including mid-altitude, including mid mid altitude cyclones tropical

cyclones thunderstorms and concluding with a look at tornadoes recommended pre-listening for this

episode is episode 90 on climate systems and some of the prerequisites in turn of that which gives

some basic background that will be of help in understanding

some of the concepts that I talk about here.

So, let's make a start and start talking about humidity.

I think most people have a basic idea of what humidity is.

It refers to the concentration of water vapor that's present in the air.

Evaporated water is one of the components of air.

It forms only a tiny fraction of the air, but it is very

important for the development of weather. Contrary to what a lot of people think, you can't actually

see water vapor in the air, at least under nearly all conditions. What people talk about as steam is
