A recent study unveils a crucial link between the North Atlantic Ocean and the South Asian Monsoon, highlighting the ocean's significant role in influencing monsoon patterns.
Researchers discovered that changes in sea surface temperatures (SST) in the North Atlantic trigger Rossby wave trains. These waves then spread eastward, impacting convective activity over the Tibetan Plateau (QTP).
The study found that warmer SSTs in the North Atlantic stimulate these wave trains, leading to shifts in the monsoon's behavior. This process, known as the "heat pump" effect, drives the northward movement of the monsoon.
This research underscores the interconnectedness of global climate systems, demonstrating how oceanic changes can have far-reaching impacts on regional weather patterns.
