Extreme events such as the "North China Super Sandstorms" in March 2021 have significant impacts on human life, socio-economics and agricultural production. In addition to local meteorological conditions, sea surface temperature (SST) variability in different ocean basins also contributes to sandstorm frequency through atmospheric teleconnection and wave trains. Therefore, it is of great significance to study the impact of SST variability in these ocean basins on dust activities in North China.
