A recent study by Dr. YAO Yao and Prof. LUO Dehai found that Arctic warming strengthens Ural blocking, leading to more widespread Eurasian cold events. The study suggests that the large BKS warming since 2000 weakens the meridional temperature gradient, increasing persistence of the UB.
Thermal comfort has increased in China over the past few decades due to rising temperatures and declining wind speed. The study found an average of 255 very cold and cold days per year, but a decline in cold days, with only 11 hot and very hot days per year.
Decadal variations in ENSO's predictability have decreased significantly since 2000, according to a recent study. The researchers suggest that a weakening of ocean-atmosphere coupling in the tropical Pacific is responsible for this decline, leading to more variable and less predictable weather patterns.
An international team of physicists has developed a method using Ultrahigh Energy Cosmic Rays (UHECRs) to study particle interactions, potentially revealing new physical phenomena at higher energies than the Large Hadron Collider.
A novel study reveals a method for controlling hot molecule reactions using precise temperature modulation and degree of bending. The researchers found that resonant energy positions decrease as molecular bending increases, affecting interaction likelihood with electrons.
Researchers created a reversible laser tractor beam that can repel and attract particles, moving them up to 20 centimeters with a single laser beam. The technique uses energy heating and polarization control to manipulate particles, offering new possibilities for atmospheric pollution control and tiny particle retrieval.
A recent study led by University of Miami scientist Massimiliano Galeazzi has identified the 'local hot bubble' as the dominant source of the diffuse X-ray background in space. The team measured the soft X-ray emission at low energy, confirming that it comes from a hot bubble of gas within our galaxy.
A team of researchers from Trinity College Dublin captured a drop of pitch on camera for the first time, generating over two million YouTube views. The attention came from their short and quirky story, which also sparked human interest due to a dramatic sequence of events related to an Australian experiment.
Researchers analyzed hundreds of sunset paintings to retrieve information on the composition of past atmospheres. The red-to-green ratios in these paintings correlate well with volcanic aerosols in the atmosphere, providing alternative ways to estimate pollution levels. This study validates previous findings and has implications for im...
Scientists tracked the Chelyabinsk meteor plume using NASA satellite data, observing its formation of a thin stratospheric dust belt. The plume evolved as it moved around the Northern Hemisphere, with different particles experiencing varying wind speeds.
Scientists have transmitted a secure quantum code via satellite, promising secure global communication. The experiment uses quantum states of single light quanta, making data transmission virtually un-hackable.
Yue Deng aims to protect satellites and power systems from solar wind energy bursts. Her research focuses on the Earth's magnetosphere and upper atmosphere interaction.
A new kind of fluctuation analysis reveals three atmospheric regimes: weather, macroweather, and climate. Macroweather has different types of variability than both weather and climate, making climate modeling more precise. This recognition may open up new approaches for predicting the climate.
Researchers developed a new model to understand the impact of urbanization on human health and comfort. By analyzing the urban boundary layer in Phoenix, Arizona, they created a framework to predict periods of high particulate pollution and extreme temperature fluctuations.
Researchers at Ohio State University have provided first experimental proof of a previously theoretical quantum effect, known as quantum monodromy. The phenomenon relates to molecular behavior and vibrational frequencies, with potential implications for astronomy, atmospheric science, and biology.
Physicists at NIST create an optical nose technique that can identify a single atom or molecule in gas samples with minute concentrations. The method uses infrared laser beams and mirrors to detect gases at very low pressures and varying frequencies.
The NASA Explorer MIDEX Program has selected the Auroral Multiscale Midex Mission (AMM) for a feasibility study. The mission aims to study the interaction between Earth's atmosphere and its nearby space environment, with a focus on understanding auroral phenomena.
