In the field of Numerical Weather Prediction (NWP), understanding the system's sensitivity to initial conditions can unlock a world of possibilities, including effective control mechanisms. Join us in this intriguing episode as we host Dr. Miyoshi and Dr. Sun, who delve into this chaotic yet fascinating world of NWP.

The duo discusses the Observing Systems Simulation Experiment (OSSE), a widely recognized approach for studying predictability where an independent NWP model run synthesizes "nature." They talk about their extension of the OSSE to design the control simulation experiment (CSE), where they apply a small signal to control "nature."

Through the lens of idealized experiments with the Lorenz-63 three-variable system, Dr. Miyoshi and Dr. Sun reveal that it's possible to control "nature" to remain in a chosen regime, thereby av ...
