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.
Numerical weather prediction models are typically used to model and forecast weather patterns. These models use mathematical equations to simulate the behavior of the atmosphere based on current and past weather data.
There are generally two types of weather models: numerical weather prediction models, which use mathematical equations to simulate the atmosphere's behavior, and statistical weather models, which use historical data to make predictions based on patterns and trends. Numerical models are more commonly used for short-term forecasts, while statistical models are often used for long-term climate projections.
no Actually yes they are, the US National Weather Service uses them to make extended forecasts out several weeks repeating updating them using the lasted collected data every few minutes.
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.

A physical model replicates a physical system using physical components, while a mathematical model represents a system using mathematical equations and relationships. Physical models provide a tangible representation, while mathematical models focus on quantifying relationships and predicting outcomes.

Weather models use complex mathematical equations to simulate the behavior of the atmosphere. They take in data from various sources like satellites, weather stations, and balloons to create a detailed picture of current conditions. By running simulations based on this data, weather models can predict how the atmosphere will evolve over time, allowing meteorologists to forecast future weather conditions.
A physical model is an object that represents whatever you are trying to explain. A mathematical model is an equation that shows something (usually some sort of movement or energy might not be applicable in most situations.)
Anything that attempts to artificially simulate some phenomena using a computation. Weather prediction is a good example.
Numerical weather prediction models are commonly used for making short term weather forecasts. These models incorporate current weather data and use complex mathematical equations to predict how the atmosphere will evolve over the next few hours to a few days. These models are run multiple times a day to provide updated forecasts.
