Computer simulations are used to predict the weather. A computer simulation is a kind of model. Large amounts of data are entered
into the computer. Then the computer performs complicated calculations with the data. The result is a prediction about what the
weather might be like in the coming hours or days.
Why are computers widely used for modeling weather systems?
because weather systems are too complicated to be accurately predicted using small-scale
models
D
because weather systems are too large to study in controlled experiments
because weather systems are too complicated to be studied with instruments and satellites
because weather systems are too large to be observed in nature

Explanation:

Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions.[1]

Process of building a computer model, and the interplay between experiment, simulation, and theory.

Computer simulations are realized by running computer programs that can be either small, running almost instantly on small devices, or large-scale programs that run for hours or days on network-based groups of computers. The scale of events being simulated by computer simulations has far exceeded anything possible (or perhaps even imaginable) using traditional paper-and-pencil mathematical modeling. In 1997, a desert-battle simulation of one force invading another involved the modeling of 66,239 tanks, trucks and other vehicles on simulated terrain around Kuwait, using multiple supercomputers in the DoD High Performance Computer Modernization Program.[2] Other examples include a 1-billion-atom model of material deformation;[3] a 2.64-million-atom model of the complex protein-producing organelle of all living organisms, the ribosome, in 2005;[4] a complete simulation of the life cycle of Mycoplasma genitalium in 2012; and the Blue Brain project at EPFL (Switzerland), begun in May 2005 to create the first computer simulation of the entire human brain, right down to the molecular level.[5]

Because of the computational cost of simulation, computer experiments are used to perform inference such as uncertainty quantification.[6]
