Weather systems

When you think about how important the weather is for us, it is rather amazing that most people don’t think about how it comes to be. Of course we all have that weather app (or if you are like me, you have about five of them as they all tell a slightly different story for today’s weather).

And we read about – better: skim over –  climate change, El Nino and all other things we take for granted. But most of us don’t look any deeper. It rains today, bugger.

Any sailor and any pilot will have a different view. We are deeply interested in the weather, now, in an hour and for the duration of the trip. And we want to understand where that weather originates, what makes it happen. Because we know that with the slightest change of factors, the weather changes also.

It’s not magic. It is all about systems, lows and highs, cyclonal and anticyclonal movements, air movements, air density, humidity, wet bulb temperatures and a bit of a guess. The last is what the weatherman does. And if he or she is good, that’s magic.

Melbourne is a bit awkward. We are close to the roaring fourties, have an awful lot of water around us and have a desert – or better: an overheated dry land mass – starting less than an hour’s flight away. That’s why you read things like “four seasons in one day” and “if you don’t like the weather, wait 15 minutes”.

It makes for beautiful skies though. So sitting in my fav seat and just staring out of the window is never dull.
