Computers can crunch numbers faster than humans can and since weather scientists can pull current and past weather data from various weather authorities (like the NOAA, etc), they can plug in the data for the computer to calculate the most scientifically reasonable prediction as possible where as if we ask any average person for an accurate prediction, we cannot verify its validity or if it's scientifically possible.
Climate models have several purposes. They are used to understand present climate and what factors create a particular climate in any one region. They are used to project climatic conditions into the future. Finally, climate models are a tool to find out what natural processes or human activities may affect a region's environment in the future.
In simple terms - the computer has a HUGE database of weather patterns, wind speeds, rain-fall and other info from previously observed conditions. These 'records' go back many years - even centuries. The computer uses this existing data, to predict what the weather should be like over the following few days.
This is so because computers make more accurate measurements and mathematical calculations. It removes the human error which takes some things for granted as a rule.
The Intel Xeon does not exactly make parts for Dell Computers. Intel Xeon is a technology and it is used in several models of Dell computers. Along with several other models, the Dell Precision T3500 contains the Intel Xeon technology.

An individual can surf or browse the internet and compare the same brand of computers, as well as different brands; for instance Apple, Dell, and Hewlett Packard via comparison online shopping at retail stores such as Sam's, Wal-Mart, Best Buy, or Circuit City. The individual could compare computer prices or deals, and the accessories being offered.
Acer Aspire offers well over 100 different models of laptop computers. Most models, such as the 1410 and 5741 Z, feature water resistant screens. Others, such as the 8920G, have built in Blu-ray drives. In addition, Acer Aspire laptops include a line of subcompact notebooks like the Aspire One as well as Ultrabooks, including the Aspire S5, said to be the world's thinnest Ultrabook.
Physical models are models you can touch
Computers are needed for the mathematical models that represent weather because they have the high data processing speed and capacity required for the computations. Computers also provide the means of presenting this information in an organized way.
Speed and low error rate.
Mathematical models are increasingly being used nowadays to represent almost anything that scientists wish to examine. Therefore there is very likely to already be a mathematical model for a human heart. So the answer is yes.

Yes. Most modern forecasts are based on computerized weather models. Computing how terrain, water, humidity, temperature, and pressure will affect the weather in different locations requires very complex mathematical formulae, too complex to be solved quickly by a human. Computers can solve such equations far more easily and, given enough computing power, can give weather forecasts for the whole planet.
Models can be use to describe many different environments. Computer models represent physical and mathematical environments. They can also describe real life environments.

A mathematical model is made up of mathematical equations and data.
