Abstract A previous study found that the September–October (SO) Antarctic Oscillation (AAO) shows an out‐of‐phase variation of late January–February (JF) wet and cold weather (wet–cold) in southern China. This explored underlying mechanism sea ice may be responsible partially for such a relationship. The SO AAO stimulates sea‐ice dipole pattern (ADP) anomalies, which induce anomalous convective precipitation Inter‐Tropical Convergence Zone (ITCZ) Latin America‐Atlantic (LAA) Western Pacific...
Abstract Based on the Empirical Orthogonal Functions decomposition of Sea level pressure (SLP) anomalies over southern extratropic, second pattern is defined as a mode (SMD 2 ), and its corresponding principal component named index. The most significant feature SMD seesaw SLP, which indicates opposite phase Amundsen Low surroundings. spatial EOF2 varies in different months but March similar to . This study shows that negatively associated with June precipitation China. mechanisms can be...
Abstract The Antarctic Oscillation (AAO), which is the main mode of extratropical circulation in Southern Hemisphere, also has a substantial effect on Northern Hemisphere climate. We investigated influence early AAO frequency late severe pollution events (SPEF) Beijing–Tianjin–Hebei region (SPEF BTH ) China during winter. results show that winter (December–January–February) SPEF negatively correlated with from previous autumn (August–September–October). controlling mechanism can be briefly...
Investigating the physical mechanism behind formation of summer heat-drought weather (HDW) in Yangtze River Basin (YRB) holds significant importance for predicting precipitation and temperature patterns region as well disaster mitigation prevention. This study focuses on spatiotemporal July–August (JA) HDW YRB from 1979 to 2022, which is linked partially preceding May–June (MJ) Antarctic Oscillation (AAO). Key findings are summarized follows: (1) The MJ AAO displays a marked positive...
Abstract This study investigates the interannual cross‐seasonal association between winter energetic particle precipitation, which is related to geomagnetic activity (GA), and southern annular mode (SAM) in following summer by employing ERA5 reanalysis dataset. The results reveal a marked negative correlation these variables on an timescale. Therefore, we analyse GA signatures atmosphere find that evolution of SAM phase driven may be caused two mechanisms: First, for high levels, middle...
The leading mode of the singular value decomposition (SVD) geopotential height (GPH) and boundary layer structure index (BLSI).
<p>The Antarctic Oscillation (AAO) is the dominant mode of southern extratropical atmospheric mass variability which has potential influences on Northern Hemisphere (NH). This study reveals a significantly negative correlation between September-October (SO) AAO index and occurrence rate following January-February (JF) wet cold weather in Middle Lower Reaches Yangtze River Basin (MLRY) China. The latter quantified by Precipitation-Temperature (PT) Index. JF PT modulated both...
