Plateau

The breaking of orographic gravity waves induces a zonal wave drag in the middle troposphere, which destroys the geostrophic balance of the large-scale westerly flow and thus drives an ageostrophic meridional circulation across the Tibetan Plateau. The rising branch of the meridional circulation acts to lower the pressure and increase the meridional pressure gradient to the south of the Tibetan Plateau by dynamically pumping the lower-tropospheric air…

Radiative components and surface heat fluxes between the Tibetan Plateau and Yangtze River region. The base map of the image is a map of China. Credit: Nan Yao Land–atmosphere interactions play a crucial role in shaping Earth's climate system, profoundly influencing weather patterns, climate variables, and ecological processes. Despite being located at similar latitudes, the Tibetan Plateau (TP) and Yangtze River region (YRR)…

The spatial distribution of summer precipitation anomalies (units: mm day-1) in 2050-2099 over Tibetan Plateau under the SSP5-8.5 scenario. The dots denote regions where at least 80% of the models agree on the sign of change. The black line indicates the boundaries of the TP, where the elevations are above 2,500 m. The baseline climatology refers to the period from 1965-2014, and the mid- and long-term is from 2050-2099. Credit: IAP…

Simulated "mobility highways" of farmer-herder interactions overlaid with the geolocated archaeological sites dated between ca. 3600 and 2200 before present. Credit: Xinzhou Chen The 1 million-square-mile Tibetan Plateau—often called the "roof of the world"—is the highest landmass in the world, averaging 14,000 feet in altitude. Despite the extreme environment, humans have been permanent inhabitants there since prehistoric…

DOI: 10.1016/j.epsl.2023.118549 A team of oceanographers, geologists and Earth scientists affiliated with multiple institutions in the U.S. and Germany has learned more about the history of the Melanesian Border Plateau by studying rocks they retrieved from the ocean floor in 2013 along with seismic data. Their paper is published in the journal Earth and Planetary Science…

A strong overnight earthquake rattled a mountainous region of northwestern China, authorities said Tuesday, destroying homes, leaving residents out in a below-freezing winter night and killing 127 people in the nation's deadliest quake in nine years.The magnitude 6.2 earthquake struck just before midnight on Monday, injuring more than 700 people, damaging roads and knocking out power and communication lines in Gansu and Qinghai provinces, officials and Chinese media reports said.WATCH | Aftermath of the earthquake: See…
