A time-lapse animation of H2O plumes during 2022-02 to 2023-01 from Microwave Limb Sounder observation (red) and the Whole Atmosphere Community Climate Model (WACCM) simulations (ensemble mean in black while ten realizations in gray). The number on the upper right corner marks the interval for plotting H2O. Overall, MLS observations and model-simulated H2O plume show good agreement. The water plume has spread to most of the globe in the stratosphere.
