Studying the response of rainfall and aridity in the semi-arid African Sahel region to radiative perturbations is a matter of pressing humanitarian relevance, considering the region is highly sensitive to changes in monsoon precipitation, as much of the region’s workforce is employed in the agricultural industry (Hamro-Drotz and Programme 2011...
A new paper, led by AOS Postdoc Yan Yu, assessed the drivers and predictability of seasonal changes in African fire and was published today in Nature Communications.
How far in advance can accurate predictions of regional summer sea ice be made? Recent work has shown evidence for an Arctic sea ice spring predictability barrier, which may fundamentally limit the accuracy of predictions made before May. However, the physical mechanism for this barrier has remained elusive.
Local variations in climate are not likely to dominate the first wave of the COVID-19 pandemic, according to a Princeton University study publis
Climate and marine scientists have so far been unable to provide satisfactory explanations as to why parts of the Southern Ocean have bucked the trend of global warming. Now a group of scientists from ETH Zurich and Princeton University has solved the puzzle with the help of simulations with a high-resolution ocean model.
Although global mean temperature has been rising since the mid-twentieth century and can be attributed to increases in emissions of greenhouse gasses, the annual number of global tropical cyclones (TCs) has remained steady at around 86 since 1980.
Hurricanes moving slowly over an area can cause more damage than faster-moving storms, because the longer a storm lingers, the more time it has to pound an area with storm winds and drop huge volumes of rain, leading to flooding.
