Exploring wintertime regional haze in northeast China: role of coal and biomass burning
2020-05-08
As one of the intense anthropogenic emission regions across the relatively high-latitude ( > 40°N) areas on Earth, northeast China faces the serious problem of regional haze during the heating period of the year. Aerosols in polluted haze and haze formation in northeast China are poorly understood compared with the haze in other regions of China such as the North China Plain.In this study, Zha...
How climate intervention options could affect the land carbon cycle ?
2020-04-30
A number of radiation modification approaches have been proposed to intentionally alter Earth’s radiation balance to counteract the anthropogenic warming. However, only a few studies have analyzed the potential impacts of these approaches on the terrestrial plant carbon cycle. Here we simulate four idealized radiation modification approaches, including direct decrease of the solar irradiance, inc...

The North Atlantic sea surface temperature (SST) anomalies can affect the climate variability in the surrounding regions. The tropical Pacific SST anomalies associated with El Niño and La Niña events is an important factor of the North Atlantic SST variations is. In this study, Wu et al. (2020) investigated the dependence of the northern tropical Atlantic (NTA) SST response to El Niño and La Niña ...

Insights into the dynamics of coastlines and tidal flats at fine spatial and temporal resolutions are essential for sustainable development. Previous studies were generally conducted at relatively coarse temporal intervals, which hardly captured detailed coastal dynamics, especially in rapidly developing islands. In this study, we developed a new method to map the monthly changes in coastlines and...
Distinct Orogenic Processes in the South‐ and North‐Central Tien Shan From Receiver Functions
2020-03-25
The high relief in the Tien Shan mountains is the product of compressional tectonics due to transmitted stress from the India-Eurasia collision. However, it remains an enigma regarding the geodynamic processes at depth, which are responsible for this surface reconstruction.In the study of Zhang et al. (2020), they take advantage of the receiver functions derived from an orogen‐perpendicular array ...

The high conductivity anomalies observed in the oceanic asthenosphere have shown anisotropic signature parallel to the plate motion. Anisotropic alignment of partial melt has been considered to one of probable explanations for the observed anisotropic conductivity structure, but the minimum melt fraction estimated from laboratory-based conductivity measurements disagrees with that estimated from t...

The tropical cyclone (TC) activity over the western North Pacific (WNP) and its year to year variation is a big concern to the society as TCs may cause large damage. In this study, Wu et al. (2020) investigated reasons of interdecadal changes in the relationship between the WNP TC genesis and tropical Indian Ocean (TIO) and tropical North Atlantic Ocean (TNA) sea surface temperature (SST) in early...

The geometry and evolution of fluvial systems are thought to be related to surface uplift. In eastern Tibet, rivers exhibit peculiar drainage patterns but how these patterns were established and their connection with the plateau uplift are still under debate.Yang et al. (2020) used a multi-disciplinary approach including provenance analysis, thermochronometry, topographic analysis and numerical mo...

The black carbon (BC) aerosol has important radiative and environmental impacts due to its strong absorption on solar radiation. The hygroscopicity of BC is the key to determine its lifetime in the atmosphere and its interaction with clouds. However, the hygroscopic properties of BC are difficult to be characterized due to the difficulty in isolating the BC with other aerosol species using most te...
Triple junction kinematics accounts for the 2016 Mw 7.8 Kaikoura earthquake rupture complexity
2019-12-23
Deciphering complex rupture behaviors of great earthquakes and associated driving mechanisms is critical to relieving seismic/geological hazards and understanding geodynamics of specific regions. This scientific issue is particularly important to the twin islands of New Zealand. This region shows frequent volcanic and earthquakes activities, including the 2016 Kaikoura earthquake with moment magni...

The sea ice variation in the high latitude northern oceans is connected to the Arctic warming. The North Atlantic Oscillation (NAO) is a climate mode in the North Atlantic Ocean.The NAO and the northern Atlantic sea ice variations are connected with each other.Both the Arctic sea ice and NAO displays variations on various time scales, including long-term trends and interdecadal changes. In the pre...

In the study, Li et al (2019) examined the role of ENSO in the variability and predictability of the Pacific–North American (PNA) and precipitation anomalies in North America in winter. It is noted that 29% variance (Fig. 1) of PNA is linked to El Niño-Southern Oscillation (ENSO) during winter 1950/51-2017/18, and thus may be largely predictable. The remaining 71% variance of PNA is associate...
Obtaining Free USArray Data by Multi-dimensional Seismic Reconstruction
2019-10-09
USArray, a pioneering project for the dense acquisition of earthquake data, provides a semi- uniform sampling of the seismic wavefield beneath its footprint and greatly advances the understanding of the structure and dynamics of Earth. Despite continuing efforts in improving the acquisition design, network irregularity still causes spatial sampling alias and incomplete, noisy data, which imposes m...
