06/11/2024 What Is Numerical Weather Prediction? Numerical Weather Models Explained Numerical Weather Prediction (commonly known as NWP) is a method used by meteorologists to forecast the weather by solving mathematical equations that describe the behavior of the atmosphere. These equations, known as the fundamental equations of motion, conservation of mass, and thermodynamic principles, are based on physical laws governing the atmosphere's behavior.
