Caribbean rainfall driven by shifting long-term patterns in the Atlantic high-pressure system, study finds

A new study challenges long-standing climate science paradigms, finding that the Caribbean often experiences drought during intensified summer insolation due to the strengthening and westward expansion of the North Atlantic Subtropical High. This high-pressure system suppresses convection and reduces rainfall across the region.

New study reveals the role of subtle changes of Northern Westerlies in the East Asian monsoon variability

Researchers found that short interstadials trigger a northward leap of the Westerlies, facilitating near-source moisture transport and suppressing δ18O depletion. The study provides new insights into the complex dynamics behind abrupt climate changes.

India’s troubled history of monsoon droughts of the last millennium revealed by stalagmites and historical documentary sources

A new record of past Indian monsoon drought history has been developed using oxygen isotopes in stalagmites, correlating with historical accounts of severe droughts and societal changes. Protracted droughts tend to occur in clusters within decades-long intervals of weaker monsoon rainfall.
