why is it that, with all the current technology, the weather man is so often VERY wrong?

Answer 1

Weather is not predictable.

Answer 2

I don't agree with you, I don't think that the weather forecasts are often wrong. Besides - what is wrong? If the forecast says that the maximum temperature on a certain day will be 22 degrees C, but it turns out to be 23, is the forecast wrong? If the forecast says "local rain showers", and there is a rain shower over your neighbor's house but not over yours, is the forecast wrong?

What has surprised me many times, is how little attention people actually pay to what is said in the weather report. For instance: the weather man says "... with rain showers in the northern part of the country", but the listener hears only "RAIN", and thinks that he will have rain all day, even though he lives in the southern part of the country. Forecasters do their best to express themselves clearly and accurately, but it doesn't always help.

But of course, sometimes the forecasts are really wrong...

A forecaster uses very complex computer-generated models when forecasting the weather. These models describe what will happen in the atmosphere (for instance, concerning winds, temperature, and humidity) over the coming hours or days.

The models are not perfect, partly because the research about the weather is far from finished, and partly because the physics in the atmosphere is so complicated that some approximations have to be made.

But the biggest problem is the fact that the computer models require observational in-data. Information from weather satellites, weather radar, soundings, and weather observations are put into the computer models, and then the computer starts "calculating the weather into the future". But there are not enough weather obserations and weather radars, especially not over the oceans. If this would change, weather forecasts would improve considerably.

Answer 3

I can only speak for the Bureau of Meteorology in Australia but forecasts are correct most of the time. It is an urban myth that meteorologists get the forecasts wrong, we don't. We get blamed for the bad weather. It doesn't matter whether we forecast rain or not, if it rains on your party, you blame the meteorologists.

A question I alsways ask of those who ask questions like yours is "When was the last time the forecast was wrong?". If you have to think about it, the question itself is based on a false premise. Why don't you check the forecast as issued against the weather that occurs. You will find that the forecasts are correct.

Answer 4

Weather forecast is always conditional. It will be true if the set of conditions change in an estimated manner.Most of the time these forecasts are very helpfull.
Final knowledge/authority rests with the super power.

Answer 5

Weather is predictable but the longer the forecast the more of a guess it is. It is like shooting baskets, the further out you are the less likely it is you will make it.

Answer 6

because weather can be going the way they predict but can, without notice, change. there is no possible way of 100% correct predictions 100% of the time. it is not physically possible

Answer 7

they arent wrong that much they are right 98% of the time you just remember the times they were wrong

Answer 8

ask pa up there, he's boss.
