Abstract It is well recognized that the zonal shift in South Asian High (SAH) has pronounced influences on weather and climate anomalies over surrounding teleconnected regions. Hence, it of great importance to investigate factors related interannual variation location SAH. This study indicates anomalous atmospheric apparent heat source ( <Q 1 >) around East Europe a close relationship with SAH during boreal summer. In particular, when above (below) normal > exists, tends westward...
ABSTRACT This study investigates the impacts of El Niño–Southern Oscillation (ENSO) on duration South Asia high (SAH) that persists over southern (10°N–27.5°N, 40°E–115°E) during summer‐to‐winter transition. The findings indicate SAH displays distinct interannual variations. Specifically, is observed to manifest as more intense and rapidly revert Ocean in a short year (SD_SAH) contrast long (LD_SAH). Furthermore, SD_SAH tends appear period La Niña event developing, while LD_SAH coincide with...
<title>Abstract</title> Using precipitation data from the Mount Emei station, along with CRU and APHRODITE datasets various reanalysis products, we examined interdecadal change in relationship between summer on southeastern edge of Tibetan Plateau (SETP) tropical sea surface temperature (SST). Our findings indicate that negative correlation SETP rainfall SST central-eastern Pacific significantly enhanced 1985 to 2005 (P2) compared earlier period 1958 1978 (P1). An anomalous anticyclone belt...
ABSTRACT Haze pollution occurs in almost every winter month the Sichuan Basin, with a higher frequency January. The interannual and decadal variations of January haze are inconsistent those other months, showing noticeable sub‐seasonal variability pollution. findings this study indicate that noticeably days over Basin closely associated simultaneous sea surface temperature (SST) warming North Pacific Ocean (NPO) tropical (TPO), SST cooling southeastern Indian (SIO). When NPO warms January,...
The Community Land Model version 4.0 (CLM4.0) driven by the forcing data of Princeton University was used to simulate soil moisture (SM) from 1961 2010 over China. simulated SM compared in situ measurements International Soil Moisture Network China, National Centers for Environmental Prediction (NCEP) Reanalysis data, a new microwave based multiple-satellite surface dataset (SM-MW), and European Centre Medium-Range Weather Forecasts Interim (ERA Interim/Land) data. results showed that CLM4.0...
Abstract Previous studies indicated that El Niño–Southern Oscillation (ENSO) significantly impacts the zonal shift of South Asian High (SAH) in boreal summer. This analysis reveals influence ENSO on SAH has experienced a significant interdecadal weakening around early 1980s. Specifically, relation with SAH's before However, after 1980s, impact is weak. We further examined physical processes for change ENSO–SAH relation. It relationship between and attributable to connection Indian summer...
Based on runoff data collected at the Zhimenda station, reanalysis from National Centers of Environmental Prediction/National Atmospheric Research (NCEP/NCAR), and observation ground stations in China, this study analyzes characteristics changes source region Yangtze River (SRYR) during flood season (from July to September), relationship between antecedent rainfall, impact westerly jet (WJ) rainfall coastal zone SRYR. The results show following. SRYR displays a significant interannual...
Based on the in situ data of soil moisture-observation networks established at Maqu, Naqu, Ali, and Shiquanhe (Sq) Tibetan Plateau (TP), using five evaluation indices [Pearson correlation coefficient (R), root mean square error (RMSE), deviation (bias), standard ratio (SDV), unbiased RMSE (ubRMSE)], applicability moisture datasets [COMBINED, ACTIVE, PASSIVE, ERA5, ERA5-Land (LAND), ERA-Interim (INTERIM), CLSM, NOAH] was comprehensively evaluated. The results showed that, observation-network...
Abstract Changes in the soil freeze–thaw status will inevitably affect thermal conditions and properties of Tibetan Plateau (TP), thereby affecting its upper atmosphere, further afield East Asia even globally. In this study, using temperature simulated by Community Land Model Version 5.0 (CLM5.0), timing duration were divided into freeze start‐date, end‐date duration. Then, linear trend estimation, correlation analysis other methods, changes spatiotemporal distribution from 1979 to 2018 over...
Abstract This study developed an objective identification algorithm for the Southwest Vortex (SWV), dominant rainstorm system prevalent in China. Based on TempestExt package, newly SWV employed a 12 h minimum duration threshold, utilizing high-resolution ERA5 dataset with 1 intervals. The results reveal that precisely identifies records documented Yearbooks, achieving optimal balance of high probability detection and low false alarm rate. In addition, can detect SWVs advance, offering...
