EurekAlert April 10, 2024 Researchers in China investigated isolated deep convections (IDCs), which have a smaller spatial and temporal size than mesoscale convective systems (MCSs), over the TP in the rainy season during 2001–2020. They showed that IDCs mainly concentrated over the southern Tibetan plateau (TP). The larger IDC had intense precipitation contributing 20 %–30 % to total precipitation, with a larger percentage in July and August than in June and September. IDCs contribute more to both total precipitation and extreme precipitation over the TP compared to the surrounding plain regions. IDCs over the TP account for a larger fraction […]

New study reveals the influence of natural climate drivers on extreme monsoons in Pakistan
Phys.org October 13, 2023 Given this region’s long history of floods and droughts, the role of natural climate variability cannot be rejected without a careful diagnosis. An international team of researchers (USA – Oak Ridge National Laboratory, Princeton, Stanford, University of Tennessee, Washington State University, Northeastern University, Pacific Northwest National Laboratory, Tufts University, Italy, India) examined how oceanic and atmospheric variability has contributed to unusual precipitation distributions in West South Asia. Variations in sea surface temperatures in the tropical Pacific and northern Arabian Sea, and internal atmospheric variability related to the circumglobal teleconnection pattern and the subtropical westerly jet stream, […]
