New study reveals link between Arabian Peninsula-North Pacific Oscillation and Asian monsoon.
A new weather pattern called the Arabian Peninsula-North Pacific Oscillation (APNPO) has been discovered, linking the North Pacific high and South Asian summer monsoon. This pattern affects the Asian summer monsoon by strengthening air flows and moisture transport, leading to changes in monsoon rainfall over India and northern China. The APNPO also shows a strong connection between spring and summer, making it a potential predictor for the Asian summer monsoon.
