Antarctic Circumpolar Current flows more rapidly in warm phases
ACC warm phases climate change
2021/8/4
Our planet's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led b...
Warm oceans helped first human migration from Asia to North America（图）
Warm oceans first human migration Asia to North America
2020/12/31
New research reveals significant changes in the circulation of the North Pacific Ocean and their impact on the initial migration of humans from Asia to North America.The U.S. National Science Fou...
Urbanization delays spring plant growth in warm regions（图）
Urbanization delays spring plant growth warm regions
2019/11/22
The first appearance of bright green leaves heralds the start of spring, nudging insects, birds and other animals into a whirlwind of action. But a new NSF-funded study shows that urbanization shifts ...
Even if humans could instantly turn off all emissions of greenhouse gases, Earth would continue to heat up about two more degrees Fahrenheit by the turn of the century, according to a sophisticated ne...
Widespread snowmelt in West Antarctica during unusually warm summer
Widespread snowmelt West Antarctica unusually warm summer
2017/7/21
An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Niño blew over the continent, an international group o...
Ecology team finds leaf litter has slower decomposition rate in warm temperatures than previously estimated
Ecology team leaf litter slower decomposition rate warm temperatures previously estimated
2017/7/19
The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists. Using leaf litter data in streams from ...
A new study concludes warm climate is more sensitive to changes in CO2
warm climate more sensitive changes in CO2
2016/11/29
It is well-established in the scientific community that increases in atmospheric CO2 levels result in global warming, but the magnitude of the effect may vary depending on average global temperature. ...
Three-dimensional visualization of ensemble weather forecasts–Part 2:Forecasting warm conveyor belt situations for aircraft-based field campaigns
Three-dimensional visualization ensemble weather Forecasting warm conveyor belt situations aircraft-based field campaigns
2015/8/6
We present the application of interactive three-dimensional (3-D) visualization of ensemble weather predictions to forecasting warm conveyor belt situations during aircraft-based atmospheric research ...
libcloudph++ 1.0: a single-moment bulk, double-moment bulk, and particle-based warm-rain microphysics library in C++
single-moment bulk double-moment bulk,
2015/8/6
This paper introduces a library of algorithms
for representing cloud microphysics in numerical models. The library is written in C C C, hence the name libcloudph++. In the current release, the librar...
Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea Ice Melt, Snow Advance, and Extreme Winter Weather
Arctic sea ice statistical model the Eurasian snow winter temperatures
2015/7/16
Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the wint...
Warm-started Wavefront Reconstruction for Adaptive Optics
Adaptive Optics Wavefront Reconstruction
2015/6/19
Future extreme adaptive optics (ExAO) systems have been suggested with up to 10^5 sensors and actuators. We analyze the computational speed of iterative reconstruction algorithms for such large system...
Warm-hot gas in and around the Milky Way: Detection and implications of OVII absorption toward LMC X-3
LMC X–3 ISM
2014/12/24
X-ray absorption lines of highly ionized species such as O VII at about zero redshift have been firmly detected in the spectra of several active galactic nuclei. However, the location of the absorbing...
Results on the properties of warm molecular hydrogen in 57 normal galaxies are derived from measurements of H2 rotational transitions, obtained as part of SINGS. This study extends previous extragalac...
High-Resolution Imaging of Warm and Dense Molecular Gas in the Nuclear Region of the Luminous Infrared Galaxy NGC 6240
formation interaction,
2014/12/23
We present ~2'' resolution CO (3-2), HCO+(4-3), and 880 μm continuum images of the luminous infrared galaxy NGC 6240 obtained at the Submillimeter Array. We find that the spatially resolved CO (3-2), ...
