Short summary

Stratospheric water vapor has an impact on global temperature changes. Tropical stratospheric water vapor exhibits a clear imprint of the Quasi-Biennial Oscillation (QBO). This study compares the water vapor variations associated with the QBO between boreal winter and summer, and the seasonal difference in the stratospheric water vapor distribution under different QBO phases is revealed.
