Drastic land pattern change has taken place in the northeast region of China, which may have a significant impact on landscape and ecosystem service. Up to now, insufficient renewal use patterns limit latest assessment transition service value. Meanwhile, adaptive value improvement method should be established. To solve this issue, integrated methodology land-use monitoring—landscape analysis—t...

The purpose of this paper is to investigate acoustic characteristics which distinguish ejectives from pulmonic stops in Ingush (a Northeast Caucasian language), and to compare Ingush ejectives to those of other languages. The articulation of ejectives is relatively well understood, but their acoustic effects are less clear. Working with a native speaker of Ingush, ejectives and pulmonic voicele...

The dust event from 12 January to 17 2021 (“1.12 event”) is the first process in and earliest last two decades. 14 18 March (“3.15 was strongest storm past decade. Distribution, transport, impact on urban air quality of these typical events were studied using multi-source satellite data, a HYSPLIT trajectory model, 3D concentration-weighted model. Results show that both affected wide range area...

Abstract Ecological restoration (ER) programs play an important role in local and global climate change carbon management policy interventions. Water resource is a key criterion for assessing the sustainability of ERs. Herein, we explored spatiotemporal patterns rainfall interception (RI, component ecosystem water budgets), its drivers after ER implementation China. Further, assessed whether ER...

An intrathermocline eddy (ITE) was detected to the northwest of Preparis Channel by in situ measurements January 2018. The ITE had a horizontal extent approximately 200 km and maximum velocity 60 cm/s at core depths between 75 130 m. This generated transformation from preexisting surface-intensified anticyclonic (SAE). blocking northeast monsoon Arakan Yoma Mountains resulted weak wind stress o...
