Numerical models are mathematical representations used to simulate real-world systems and processes. They rely on numerical methods to solve equations that describe physical phenomena, such as weather patterns, ocean currents, or population dynamics. By inputting data into these models, researchers can predict future behavior and understand complex interactions within the system. These models are widely used in various fields, including meteorology, engineering, and economics. They help scientists and decision-makers analyze scenarios, test hypotheses, and make informed choices based on simulated outcomes. Numerical models are essential tools for advancing knowledge and addressing challenges in a data-driven world.
