Cities don’t just change the landscape, they change the weather. According to a new study analyzing tens of thousands of rain events in Texas, whether urban areas make rain worse, lighter or simply different depends strongly on the type of storm. The research, published in Nature, examines more than 40,000 warm‑season storms that passed over or near Dallas–Fort Worth, Austin, San Antonio and Houston between 1995 and 2017. By sorting storms into distinct categories and tracking their three‑dimensional structure using weather radar, scientists found that the four urban areas strengthen some storms while weakening others.
A new international study, published in Science Advances, fully accounts for what is driving the world's rising oceans over six decades.
Leipzig. Aerosols and clouds play a key role in the Earth’s climate budget. However, the extent to which they reflect solar energy depends heavily on how much water the particles can absorb. This so-called hygroscopicity has so far been represented in a simplified manner in climate models. An international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has now demonstrated through a global study that the models are not precise enough, particularly in urban regions. In chemically complex and polluted regions such as Delhi or Cairo, there is likely to be greater hygroscopic growth and higher water uptake, which could partly explain the observed regional cooling trends or the slower warming on the Asian and African continents, the researchers write in the journal Communications Earth & Environment, published by the Nature Publishing Group.
Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead time to prepare for inclement conditions.
Climate change is widely understood as an environmental and economic threat, but new research from the University of Sydney shows it is also a growing social crisis, weakening the relationships people rely on to survive.
