Cyclone Ian has been battered by strong wind shear, causing its bulk of precipitation to shift east and southeast. The storm's temperature varied greatly, with coldest cloud tops near -63F/-52C in some areas.
Research suggests that decreasing winter winds are a primary driver of streamflow declines and reduced precipitation in the Pacific Northwest mountains. This decrease can lead to increased wildfire risk, earlier and lower streamflows, and decreased water availability for communities and industries.
A new CU-Boulder study reveals a significant increase in dust emissions across the Western United States over the past 17 years. The research found that dust erosion is linked to an increase in calcium deposition in precipitation, with major increases observed in Colorado, Wyoming, and Utah.
Researchers used laser light pulses to study aerosol and cloud processes in atmospheric conditions. The results show that high-intensity laser pulses can increase the number of ice particles in cirrus clouds by up to a factor of 100 within seconds, intensifying their optical density and making them appear brighter.
Cyclone Imelda's weakening is attributed to strong wind shear in the Southern Indian Ocean. The storm's precipitation has been pushed southeast of its center, exposing the low-level circulation center.
NASA's Aqua satellite data reveals Tropical Cyclone 18S continues to experience wind shear, pushing precipitation away from its center. The storm's main convection is being hindered by strong easterly vertical wind shear, affecting its ability to consolidate and intensify.
Soil respiration in China varies significantly across regions, with the highest rates found in southeastern China and lowest in northwestern China. Precipitation and temperature also play a crucial role in controlling soil respiration, with increasing variability expected under warming scenarios.
Post-tropical cyclone John's cloud top temperatures warmed by 24 hours, with one tiny area of convection remaining. The remnants of the storm are moving northwest and expected to dissipate later today.
Scientists warn that chronic droughts like the 2000-04 event could become more frequent and severe, leading to ecosystem damage and reduced carbon sequestration. The region's ability to absorb carbon dioxide may decline by the end of the century, exacerbating global warming.
Researchers at the University of Pittsburgh have discovered an unexpected complexity in the patterns of drought during the Middle Ages. The study uses tree rings and oxygen isotopes to reveal that winters were wetter-than-expected during the Medieval Climate Anomaly, contradicting previous tree ring data.
A recent study by University of Innsbruck climate researchers found that land-cover changes have a limited effect on glacier loss in the Kilimanjaro area. The team's novel methodology showed that LCC mainly alter precipitation over glaciers, resulting in local increases or decreases in glacier mass.
A study published in Proceedings of the National Academy of Sciences finds a strong correlation between precipitation patterns in the Northeast and Southwest. Researchers used sediment layers to reconstruct records and found that extreme weather events are predicted by climate models.
Scientists found significant increases in annual temperatures in south-western China, with 77% of weather stations displaying statistically significant rises. Glaciers are retreating at an alarming rate, threatening natural habitats and ecosystems.
NASA's Genesis and Rapid Intensification Processes (GRIP) mission is analyzing Hurricane Earl's structure and behavior. The GRIP aircraft are equipped with instruments such as HAMSR, which provides detailed data on the storm's temperature, water vapor, and cloud liquid water distribution.
The study reveals that incorporating NASA products into the BASINS model significantly improves water quality model performance. By capturing the effects of water flow during storm periods, the NASA data systems provide a more accurate representation of non-point pollution and improve estimates of water quality.
Researchers at NC State University developed a new methodology that combines multiple general climate forecast models to improve the accuracy of winter precipitation and temperature forecasts. The tool is valuable for government officials, providing key information for predicting energy consumption and water availability.
Researchers explore Arctic river deltas as a potential source of information about past and future climate change. The sediments deposited in these delta regions can record data on sea level, productivity, storminess, and human factors affecting sediment delivery, providing valuable insights into the global carbon cycle.
Researchers found that local climate moderates the relationship between temperature, precipitation and dengue incidence. Climate patterns affect mosquito reproduction and virus development.
A recent study found that groundwater storage plays a crucial role in regulating watershed response and climate feedbacks. The depth of the water table is closely tied to land surface conditions, with shallow tables amplifying temperature increases and deep tables directly influencing precipitation patterns.
Dartmouth researchers found that North America's prevailing winds in the mid-latitudes once blew from the east, not the west. This change was influenced by a growing and intensifying northern circumpolar vortex, resulting in shifting temperature and precipitation patterns.
A NASA study suggests that a warmer climate may not result in a wetter world, with simulations showing an increase in global evaporation and precipitation. However, the atmospheric storage of water vapor decreases as temperatures rise.
A study by Alex Woods and colleagues suggests that climate change may be behind an unprecedented epidemic of dothistroma needle blight in forests. Increased summer precipitation is believed to have spread the pathogen, which typically thrives in moist conditions.
Montana State University has released a new Conserve Water Educators Guide to help inform others about basic water science topics with a focus on water conservation. The guide provides contemporary materials for educators, water managers, and community leaders to educate the public about water conservation.
Researchers investigated urbanized watersheds in four US regions over 50 years, comparing stream flow data with population growth. They found that higher population densities led to increased stream flow despite lower precipitation levels.
