Researchers found three pronounced cooling periods indicating drought, linked to African deforestation and global temperature increases. The study suggests that these changes will disrupt the monsoon system, affecting agriculture and food security in equatorial Africa.
A new study links drought in southern Africa to the warming of the Indian Ocean, contradicting earlier research that connected it to the Sahelian region. The analysis suggests a late 20th-century cooling of the North Atlantic Ocean was key to Sahelian drought, with recent warming leading to increased rainfall in the area.
A new study suggests that ancient humans' systematic burning of Australia's interior led to the desertification of the region. The research indicates that this burning altered the flora enough to decrease the exchange of water vapor between the biosphere and atmosphere, causing the failure of the Australian Monsoon over the interior.
Research on Neoproterozoic low-latitude sedimentary rocks reveals that tropical oceans were likely very cold during the Cryogenian period, leading to widespread sea ice. In contrast, a Cretaceous alluvial sequence provides evidence of long-term amplification of the global hydrologic cycle and greenhouse climate signals.
Researchers found pronounced nitrogen oxide pollution plumes extending across central Indian Ocean, mainly from Africa and southeast Asia. The study suggests that the Indian Ocean is not always pristine and that feedbacks in atmospheric chemistry can result in downwind regions being highly insensitive to upwind emissions.
The Soil Moisture Experiment 2004 aims to understand how much moisture is retained in soils, helping estimate potential flooding or water absorption. By analyzing data from satellites, airplanes, and ground teams, researchers can provide better forecasts for monsoon rainfall and water supply.
The African monsoon has two distinct seasons: a late spring season strongly influenced by sea surface temperatures near the Gulf of Guinea, and a later summer season driven by African Easterly Waves. The waves play a major role in this summer season monsoon rainfall.
Researchers will study tree rings to reconstruct regional climate histories and analyze relationships between climate variables, leading to improved long-term forecasting of the Asian monsoon's impacts on global population and agriculture.
A new monsoon forecasting method developed by Professor Peter Webster could guide farmers in choosing optimal planting times and making informed decisions about water management. This technique, applicable to any monsoon region, has the potential to create a significant increase in crop yields without relying on pesticides or fertilizers.
Researchers found that changes in SSTs affect the Madden Julian Oscillation, a key driver of South Asian monsoons. The study suggests that warmer sea surface temperatures can predict up to 30% of MJO fluctuations.
Research suggests the Asian southwest monsoon is strengthening due to Northern Hemisphere warming, with potential implications for agriculture and population displacement. The study analyzed sediment cores from the Arabian Sea, finding increased wind speeds and a link to decreased Eurasian snow cover.
The analysis of three Himalayan ice cores reveals a highly detailed record of the last 1,000 years of earth's climate in the high Tibetan Plateau. The data shows that both the last decade and the last 50 years were the warmest in 1,000 years, with at least eight major droughts caused by a failure of the South Asian Monsoon.
Researchers have uncovered clues to the cause, timing and evolution of the massive East Asian summer monsoon. The study found a connection between the disastrous 1998 Yangtze River flood and the timing and strength of the summer monsoon.
Researchers from University of Wisconsin-Madison found that shifting tropical Atlantic monsoons and increased solar radiation led to a wetter Sahel region, driving vegetation growth and increasing rainfall. This study promises to improve computer models used for climate predictions.
The monsoon's peculiar ocean currents increase nutrients, boosting plankton productivity. This boost converts carbon dioxide to organic forms, storing it in deeper layers and reducing atmospheric CO2 levels.
