(University of Illinois at Urbana-Champaign, News Bureau) Many climate models focus on scenarios decades into the future, making their outcomes seem unreliable and problematic for decision-making in the immediate future. In a proactive move, researchers are using short-term forecasts to stress the urgency of drought risk in the United States and inform policymakers’ actions now.
(SPIE–International Society for Optics and Photonics) In “Perspectives on flood forecast-based early action and opportunities for Earth observations,” Claire Nauman et al. focus on flood forecasts and identify opportunities to incorporate Earth observation data into flood forecast-based early action.
(Skolkovo Institute of Science and Technology (Skoltech)) A Skoltech researcher has developed a theoretical model of wave formation in straits and channels that accounts for nonlinear effects in the presence of a coastline. This research can improve wave prediction, making maritime travel safer and protecting coastline infrastructure.
(Desert Research Institute) Normally, we think of the freezing point of water as 32°F – but in the world of weather forecasting and hydrologic prediction, that isn’t always the case. In the Lake Tahoe region of the Sierra Nevada, the shift from snow to rain during winter storms may actually occur at temperatures closer to 39.5°F, according to new research from the Desert Research Institute (DRI), Lynker Technologies, and citizen scientists from the Tahoe Rain or Snow project.
This week, a blast of Arctic air has engulfed much of the central US, bringing freezing conditions and record low temperatures to many states. Texas, in particular, has been badly affected, with grid operators hit by power outages and struggling…

(Carnegie Mellon University) A new paper contributes to these ongoing reliability considerations by using a unique data set to determine how both low and high temperatures reduce the reliability of coal, gas, diesel, hydroelectric, and nuclear power generators and thus affect the amount of generation markets should contract for. The paper, “Resource Adequacy Implications of Temperature-dependent Electric Generator Availability,” by researchers at Carnegie Mellon University, was published in Applied Energy.
Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to researchers, who said their findings suggest that honey bees have a ‘goldilocks’ preferred range of summer conditions outside of which their probability of surviving the winter falls.
To predict when earthquakes are likely to occur, seismologists often use statistics to monitor how clusters of seismic activity evolve over time. However, this approach often fails to anticipate the time and magnitude of large-scale earthquakes, leading to dangerous oversights in current early-warning systems. For decades, studies outside the seismology field have proposed that these major, potentially devastating seismic events are connected to a range of non-seismic phenomena — which can be observed days or even weeks before these large earthquakes occur. So far, however, this idea hasn’t caught on in the wider scientific community.
