Why do weather predictions usually go wrong?

Answer 1

Can YOU predict the future?

Answer 2

I don't agree that the forecasts usually go wrong - especially not the shorter ones - but here is the reason why they sometimes go wrong:

Forecasters use computer models when they make weather forecasts. Very powerful computers simulate what will happen in the atmosphere (all around the world) in terms of temperature, humidity, wind, etc. These computer models are not perfect, since simulating the atmosphere is a very complicated thing. The models also need data from satellite images, radar images, and surface observations. Especially over the oceans, the surface observations are scarce, providing almost no in-data for the computer models.

So - a lack of observational data and the difficulty of simulating the atmosphere are the two main reasons why forecasters are sometimes wrong.

Answer 3

Because it is impossible to predict weather patterns....the best way to predict the weather is to look out the window....either its rainy or it is sunny. Warm or cold.

Answer 4

It's because weather systems can be quite finicky. They'll appear to be moving along a certain route and all of a sudden, at the last possible moment, they will change course.

Answer 5

Dunho, blame it on the weather man!

Answer 6

It's Nature dear and noone can predict it quite accurately. If anyone did he would have been GOD by now.
