The response of trees to climate is crucial for the health assessment and protection forests in alpine regions. Based on samples Pinus tabuliformis Abies fargesii, two typical evergreen coniferous species with distinct elevation differences vertical vegetation zones Qinling Mountains, we have developed tree-ring width chronologies southern slope central Mountains China. correlation analysis results showed that radial growth P. A. fargesii responded different climatic factors. Water stress...

In this work, the later-barrier reaction Cl + CH4 → HCl CH3 is investigated with an eight-dimensional quantum dynamics method [R. Liu et al., J. Chem. Phys. 137, 174113 (2012)] on ab initio potential energy surface of Czakó and Bowman [J. 136, 044307 (2012)]. The probabilities initially in its ground vibrationally excited states are calculated a time-dependent wavepacket method. theoretical integral cross sections (ICSs) extensively compared available experimental measurements. For state...

Precipitation nowcasting based on radar data plays a crucial role in extreme weather prediction and has broad implications for disaster management. Despite progresses have been made deep learning, two key challenges of precipitation are not well-solved: (i) the modeling complex system evolutions with different scales, (ii) accurate forecasts precipitation. In this work, we propose CasCast, cascaded framework composed deterministic probabilistic part to decouple predictions mesoscale...

Abstract. The Santa Barbara Basin naturally experiences transient deoxygenation due to its unique geological setting in the southern California Borderland and seasonal changes ocean currents. Long-term measurements of basin showed that anoxic events subsequent nitrate exhaustion bottom waters have been occurring more frequently lasting longer over past decade. One characteristic is development extensive mats benthic nitrate-reducing sulfur-oxidizing bacteria, which are found at...

ABSTRACT The summer rainfall in China 2016 exhibited a substantial intraseasonal feature, with an intensification June and July but suppression August over the Yangtze River Basin North China. Madden–Julian oscillation (MJO) during its impact on are investigated by conducting observational analyses diagnostic linear baroclinic model (LBM) experiments. A significant MJO activity is observed three episodes corresponding to stages of LBM utilized diagnose circulation response tropical heating...

Purpose: To investigate the compliance rates of health-related behaviors among Chinese preschool children, and to explore how supportive family environment, parental behavior, sociodemographic community factors affect children’s behavior comprehensively. Method: Preschool children aged 3 6 years were chosen from 5760 villages (residential) committees 471 counties (districts) 31 provinces by use a stratified random sampling procedure, with 10,967 3–6 old included. The survey was conducted...

Quantitative precipitation estimation (QPE) plays an important role in meteorology and hydrology. Currently, multichannel Doppler radar image is used for QPE based on some traditional methods like the Z − R relationship, which struggles to capture complicated non-linear spatial relationship. Encouraged by great success of using Deep Learning (DL) segmentation networks medical science remoting sensing, a UNet-based network named Reweighted Regression Encoder–Decoder Net (RRED-Net) proposed...

Water source is one of the most important concerns for regional society and economy development, especially in Weihe River basin which located marginal zone Asian summer monsoon. Due to weakness short instrumental records, variations streamflow during long-term natural background are difficult access. Herein, average June–July variability middle reaches was identified based on tree-ring width indices Chines pine (Pinus tabulaeformis Carr.) from northern slope Qinling Mountains central China....
