Actually computers are only a tool used so that humans can forecast the weather better.

Meteorologists write computer programs using a technique called Finite Element Analysis to model the fluid dynamics and other processes in earth's atmosphere that produce weather. A computer can perform in a few hours the calculations for several days weather in the future, while a human might take months to do the same calculations (so humans would not even bother as the results would be useless by the time they were finished). As computers have gotten faster and their memory increased in size more detailed and accurate weather modeling programs have become possible and the number of days that can be predicted have increased, making the results more useful.

However one thing that was discovered is that there is an inherent limit to how good a weather forecast can be. While the equations used in these Finite Element Analysis programs are completely deterministic, they are extremely sensitive to changes in initial conditions. This is a mathematical phenomenon called Deterministic Chaos. It was later discovered that Deterministic Chaos is not just mathematical but an inherent property of many real world physical systems: undelectably small disturbances to the state of a system can grow chaotically over time into enormously different states, making such systems unpredictable and seemingly random. Both the real system and any model of it have this unpredictability and will always deviate if the model is not periodically corrected and restarted to match (as best as possible) the measured state of the real system.

Humans however are much better than computer programs at making very short term weather forecasts. This is just basically the same way they did it before computers became available: by "looking out the window" and asking other meteorologists in nearby towns what they were "seeing" too.

Will computers ever be smarter than humans?

No, because humans invented computers so computers cannot be smarter than humans.


What is the hexadecimal code?

This is a code that computer programmers use to better communicate with computers. Because computers operate on a binary code system that is difficult for humans to understand, a code that made communicating with computers easier.


Without technology how would forecast the weather?

Depends on exactly how much of a lacking of technology we're talking about. In the old days without computers, forecasters used weather instruments (thermometers, barometers, etc.) to take measurements at ground level along with weather balloons to measure conditions up in the atmosphere. This will give a basic idea of the short term weather (next day or two) although the risk is high that the forecast will not turn out correct. This is the same process that is done today, however the measurements are entered into computers that can do millions of physics equations in a short amount of time at speeds that no human could do. These millions of complex equations allow for a much more accurate forecast than relying on just a few basic equations done by a humans. The science and technology still is not adequate enough to produce an accurate forecast at all times, but the accuracy has improved significantly with computer model technology. Some may define weather instruments (thermometers, barometers, etc) as "technology"...If you consider that to be technology and take those out of the equation, then you're more or less depending on what you can feel and see. For example, you can see signs in the clouds that a storm system is approaching or that thunderstorms are getting ready to develop. You can also feel if temperatures are warming/cooling or if it's becoming more humid. These can give a half-way accurate forecast for the next few hours, but are completely useless after about 12 hours. The invention of weather instruments allowed for a very accurate forecast for the next few hours and a half-way accurate forecast up to about 2 or 3 days in advance. Now with computer model technology, it allows on average for a very accurate forecast for 2 to 3 days, with a half-way accurate forecast up to the 7 to 10 day range.

What do humans do better than computers?

There is nothing a computer can do that a human cannot do. A computer simply computes and acts according to those computations. Humans can do exactly the same, the only differences being that computers can do it many times quicker and with far greater consistency and accuracy.

Why human is better than human?

It depends on the task you are trying to accomplish. For easy tasks, such as adding 2 and 2, humans far out-succeed computers. But when it comes to larger, more complicated computations, computers excel and are able to perform the computation much faster than humans.
