Interdecadal moisture patterns and teleconnections in Monsoonal Asia over the past seven centuries
ABSTRACT Interdecadal (10‐ to 100‐year oscillation) moisture variations over the Monsoonal Asia ( MA ) is highly variable across regions and time, which are relatively less understood due to the shortness of the instrumental data of a few decades. In this study, comprehensive investigations on the s...

ABSTRACT Interdecadal (10‐ to 100‐year oscillation) moisture variations over the Monsoonal Asia ( MA ) is highly variable across regions and time, which are relatively less understood due to the shortness of the instrumental data of a few decades.
