Why can’t computers predict the weather far into the future?

213 views

I guess I’m assuming.. Bare bones, everything out there has a scientific reason for acting the way it does. Wind, humidity, temperature, yadda yadda. What randomness is preventing us from entering all the values into a computer program, hitting fast foward, and seeing close to exactly how things will be far down the road?

I’m going to draw a grid on the ground, then throw a grain of rice at it. It’s your job to predict where it lands.

Eventually, if you set up a computer with a high-speed camera and lots of information about which direction the wind is blowing right at the very moment and the exact mass and shape of the grain of rice, it will probably get pretty good at predicting where that grain will fall!

Now, I’m going to throw an entire bucket of rice, and I’m going to keep going it with more buckets non-stop. After I throw the *first* one, I want you to predict where the 18th grain from the 10th bucket will land.

Good luck. ;p

In a system with lots of parts that all affect each other, you can calculate for lots of variables as they are now – but then calculating for a hundred ways they *might be* tomorrow, and a thousand ways they *might be* the day after that, and ten thousand ways they *might be* the day after that, gets…messy.
