And it looks like somebody's got a broom and swept a pile of leaves onto the eastern side at the base there.
It's weird.
It looks like somebody's tidying up.
But actually, it's just a nice leafless compass.
So a really nice simple one is if a cloud is taller than it is wide, it's a classic sign that the atmosphere is unstable.
That makes rain showers more likely, particularly if you see them in the morning.
It makes thunderstorms more likely.
It makes hail more likely.
But as a general rule, you know, it's hard to go a whole week without there being a fantastic pattern to decipher in the sky.
Thanks so much, Mike.
Thanks so much for having me on, and congrats on such a successful show.
So if you look at a tree from all directions, you walk around one, you'll very quickly realize that there's no such thing as a symmetrical tree. And on average, there's just more tree. There are bigger branches and more branches and more leaves on the southern side.
There are some big signs that people may be loosely familiar with, but the really undiscovered world, and the reason I ended up writing a book with the title, The Secret World of Weather, is the smaller signs, the things that are going on, you know, sometimes within touching distance.
And that's what gets me really excited is when I go outside and I go, wow, how did I not notice that for 20 or 30 years? And suddenly it's there in front of me. And that's
yeah that's what fired me up for the last three years so give me an example of you walking out and saying how did I not notice this for the last 20 years what like what I'll give you a couple one um so much of the small weather signs are related to to the key forces of the the sun and the wind there's a a thing called a sun pocket which is where
we can find a place in a landscape which is a lot warmer than even somewhere only 30 feet away. And to do that, we just have to be, we have to find a spot that's in direct sunlight. You know, it's no great surprise that being in the sun is warmer than being in the shade.
But the slightly cunning thing is, you get these really super warm pockets if you can find somewhere that is both in the sun, but actually has shelter directly above you. And that stops the heat escaping vertically upwards. So as an example, February of this year, I went out with a picnic. It was very cold.
And by finding a spot underneath a conifer where the sun could reach in, a low winter sun could reach in, but the heat couldn't escape upwards, I was able to sit there very comfortably for 20, 25 minutes. But if I'd moved out from under the tree, and it's a little bit counterintuitive, we'd sort of imagine being out in the open and the sun would be warmer.
It would have been far too cold to sit around eating a picnic. Equally, the wind behaves very differently around any obstacles, but let's stick with trees for now. If you're moving across an open area and you get used to feeling the breeze, what you can notice is that the breeze accelerates underneath an isolated tree.
If we think of a sort of almost like a stereotypical tree with a nice big green canopy and a gap underneath where we see the tree trunk, if you walk in underneath that canopy, the breeze will accelerate. The physics is the same as the way air accelerates over an aircraft wing. It will actually accelerate underneath the tree.
