Weather models rely on fundamental fluid dynamics equations, such as partial differential equations and the Navier-Stokes equations, to simulate and forecast atmospheric conditions.
The claim is a well-established empirical fact regarding meteorological science. Multiple papers (0, 1, 4, 5) explicitly confirm that numerical weather prediction models use fluid dynamics equations (like partial differential equations and the Navier-Stokes equations) to simulate atmospheric conditions. Therefore, the verdict is SUPPORTED.
