Abstract In boreal summer of 2022, Pakistan experienced extremely high rainfall, resulting in severe flooding and displacing over 30 million people. At the same time, heatwaves persisted central China Europe. The coexistence these extreme events suggests a possible linkage. Our analysis indicated that record rainfall was mainly induced by compounding factors. These included (1) La Niña-induced strong anomalous easterlies northern Indian subcontinent, (2) intense southerlies from Arabian Sea...
Abstract The record mei-yu rainfall occurred in the Yangtze–Huai River valley (YHRV) and Japan regions early summer (June–July) of 2020 devastated these regions. Whereas several studies had been devoted to physical processes behind this climate extreme, impact upward trend ocean atmosphere was less investigated. In study, potential effect linear on extreme assessed by comparing event with a 1998 event. distinction between June July focus. June, significant increasing trend, accompanied an...
Abstract The westerly wind burst (WWB) is an important triggering mechanism of El Niño and typically occurs in the western Pacific Ocean. Fourier spectrum field over tropical characterised by a large variety peaks distributed from intra-seasonal to decadal time scales, suggesting that WWBs could be result nonlinear interactions on these scales. Using combination observations simulations with 15 coupled models Coupled Model Intercomparison Project Phase 6 (CMIP6), we demonstrate main drivers...
Abstract The cross-basin interaction of the second EOFs interannual SST in North Atlantic and Pacific—the tripole (NAT) Pacific meridional mode (PMM)—is discussed. Observations revealed that total variances NAT PMM have simultaneously experienced interdecadal enhancement since 1990s. Wavelet analysis indicated this was associated with variations (8–16 years) PMM, which become significantly positively coherent This variation also changed NAT–PMM relationship from negative to positive....
Abstract In the boreal summer of 2022, Pakistan suffered record rainfall that led to severe flooding and left more 30 million people homeless. At same time, a heatwave persisted over central China. The concurrence these extreme events suggests possible linkage. Our analysis climatic data indicated was triggered by an extratropical cold-dry northerly associated with European blocking interacting unusually strong warm-moist southerly flow from Arabian Sea at Pakistan. Both flows joined...
Abstract In this study, we investigated the triple‐dip La Niña during 2020–2022 by comparing it with previous (1973–1975 and 1998–2000) events. We found that cold sea surface temperature (SST) in eastern equatorial Pacific was moderate study period; however, accompanying near‐surface easterly wind anomaly unusually stronger its lifecycle than two The maintenance of appeared to be attributable strong zonal SST gradient. gradient resulted from La‐Niña‐associated interannual anomaly, which...
Abstract In the early 1990s, mei-yu rainfall over South China in boreal summer exhibited an abrupt change and northward extension. This altered pattern of East Asian from a dipole-like to monopole-like pattern; that is, out-of-phase relationship between south north Yangtze Huaihe River valley changed in-phase relationship. The physical processes potentially responsible for triggering this were analyzed study. Our observations revealed western North Pacific subtropical high (WNPSH), sea...

At the same time, heatwaves persisted over central China Europe. The concurrence these extreme events suggests a possible linkage. Our analysis climatic data indicated was mainly induced by compounding factors, including 1) an unusually strong anomalous easterlies associated with La Niña northern Indian subcontinent intense southerlies, further...
Abstract In this study, the effect of multiple timescale wind fields on westerly bursts (WWBs) was investigated during onset super (1982, 1997, and 2015) moderate El Niño events. The results revealed that extreme WWBs group were attributed to low-frequency (≥90 days, LFW), medium-frequency (20–90 MFW, or intraseasonal) high-frequency (≤10 HFW) components, accounting for approximately 51%, 33% 16%, respectively. Thus, Niños primarily contributed by LFWs MFWs. By contrast, determined MFWs...
