Characteristics of the Atmospheric Rivers in Snowstorms Caused by Extratropical Cyclones in Northeastern China

open access: yesGaoyuan qixiang, 2023
A statistical study on snowstorms in northeastern China caused by extratropical cyclones with and without the support of atmospheric rivers (ARs) was conducted using conventional observations, 6-hour and 24-hour precipitation data, as well as ERA5 ...

The Influence of Five Teleconnection Patterns on Wintertime Extratropical Cyclones over Northwest Pacific

open access: yesAtmosphere, 2020
Extratropical cyclones (ETCs) over the Northwest Pacific are identified and tracked by applying an objective tracking algorithm to the 6-h time interval relative vorticity fields from the European Center for Medium-range Weather Forecasts (ECMWF ...

Optically Transparent Flexible Broadband Metamaterial Absorber Based on Topology Optimization Design

open access: yesMicromachines, 2021
A conformal metamaterial absorber with simultaneous optical transparency and broadband absorption is proposed in this paper. The absorptance above 90% over a wide frequency range of 5.3–15 GHz can be achieved through topology optimization combined with a

Compositional analysis

open access: yesEuropean Journal of Public Health, 2023
Abstract Health outcomes are often multi-faceted as many environmental variables have synergistic impacts. By integrating data on chemical agents from the lithosphere, hydrosphere, and atmosphere, it will be possible to note the roles each play, and which are having the most demonstrable effect on long term cognitive health outcomes ...
