Abstract This study explored the interannual relationship between autumn Arctic sea ice concentration (SIC) and subsequent summer precipitation over East Asia (EASP). Since late‐1990s, declining SIC in Kara–Laptev Seas has been significantly correlated with EASP as well extremely positive anomalies northern China intensely negative central‐eastern Asia. However, there was a weak correlation before late‐1990s. Furthermore, anomalous pattern its connection variability can be explained by...
The Altyn Tagh Fault (ATF) is one of the major left-lateral strike-slip faults in northeastern area Tibetan Plateau. In this study, interseismic deformation across ATF at 85°E was measured using 216 interferograms from 33 ENVISAT advanced synthetic aperture radar images on a descending track acquired 2003 to 2010, and 66 15 an ascending 2005 2010. To retrieve pattern strain accumulation, global atmospheric model (ERA-Interim) provided by European Center for Medium Range Weather Forecast...
Abstract On 23 June 2020, an Mw 7.4 earthquake struck offshore Oaxaca, Mexico, providing a unique opportunity to understand the seismogenic tectonics of Mexican subduction zone. In this study, near-field coseismic deformation caused by event was retrieved from Global Positioning System (GPS) observations and Interferometric Synthetic Aperture Radar (InSAR) measurements. Given static geodetic measurements, high-rate GPS waveforms, teleseismic fault geometry rupture process for 2020 Oaxaca...
ABSTRACT Using the ERA ‐20th century reanalysis data for period 1900–2009 and NCEP / NCAR 1948–2016, this work inspects interdecadal variations between Arctic Oscillation ( AO ) surface air temperature SAT in East Asia, then investigates possible mechanisms, finally considers a recent switch of AO–SAT relationship. It is revealed that relationship statistically significant during 1928–1948 1975–1995. means positive associated with weakening sea level pressure SLP gradient over Asian trough,...
Abstract The arid/semiarid region of Northwest China (NWC, north to 35°N, and west 100°E in China) experienced significant wetting after the late 1980s. We used both summer precipitation standardized indices (precipitation index [PI] index) reexamine regime shift. Consistent with rainfall, drought condition represented by was significantly alleviated over most areas NWC during P2 (1989–2016) than that P1 (1961–1988). Along increased rainfall NWC, changes also occur interannual...
Since there are many destructive effects caused by extreme climate events in the Yellow River, it is of great theoretical and practical significance to explore variations climatic extremes this key basin. We used a meteorological dataset from 66 stations within River basin (YRB) for period 1960–2017 calculate magnitude frequency precipitation/temperature extremes. also analyzed relationships between main large-scale atmospheric circulation patterns (ACPs) The trends precipitation were...
Previous studies reveal robust lake expansion on TP since the late 1990s. Debate quantitative contribution from precipitation and other factors including glacier melting continues, but with more evidence showing that dominates interdecadal increase in inner water storage. However, level changes (LLCs) potential connection regional at interannual timescale underlying atmospheric processes, especially for extreme years, remain unclear yet. The year 2015 2018 witness largest decrease some major...
On 20 April 2013, a moment magnitude (Mw) 6.6 earthquake occurred in the Lushan region of southwestern China and caused more than 190 fatalities. In this study, we use geodetic data from nearly 30 continuously operating global positioning system (GPS) stations, two periods leveling data, interferometric synthetic aperture radar (InSAR) observations to image coseismic deformation earthquake. By using Helmert variance component estimation method, joint inversion is performed estimate source...
Abstract This study examines August droughts in northern China (north of 35°N) at interannual and interdecadal timescales. During the period from 1968 to 1992, precipitation western eastern regions showed an out‐of‐phase pattern. 1994 2018, climate Tarim Basin became wetter, but there was no significant connection with drought North China. Further studies demonstrated that Atlantic sea surface temperature (SST) regional soil moisture anomalies were related changes Before early 1990s,...
Abstract This work investigates the nonsynchronous relationship between North Atlantic Oscillation (NAO) and winter European precipitation. The results indicate that linkage early-winter (November December) NAO following January precipitation atmospheric circulation over sectors became statistically significant after late 1980s. Before 1980s, are weakly correlated with NAO. After by contrast, positive phase of is generally followed an anomalous meridional dipole pattern barotropic structure...
By using Sentinel-1A ascending and descending synthetic aperture radar (SAR) data, this paper extracts the high-precision interferometric SAR (InSAR) coseismic deformation of 2016 Menyuan Mw5.9 earthquake, inverts fault geometry slip distribution simplex method nonnegative least squares method, constructs deep model regional zone. The results show that earthquake is dominated by surface uplift, maximums along line-of-sight direction tracks are 5.3 cm 7.1 respectively. strike dip angles 133°...
Business intelligence is a key means to promote core competence of enterprise. However, the enormous construction cost business severely limits popularization and development intelligence.
