Which consequence of nonlinearity limits weather forecasting?
Answer: A
Nonlinear interaction transfers error from small scales to large, so a small initial uncertainty grows until the forecast is no better than climatology, which Lorenz established and which sets a practical limit of about two weeks. Numerical integration is entirely possible and energy is conserved by well constructed schemes. The predictability limit is a property of the physics rather than of the numerical method, which is why ensemble forecasting rather than better arithmetic is the response.
