The intraseasonal reversal of the temperature over East Asia and sudden stratospheric warming (SSW) are two abrupt events during winter 2020/21. characteristics these their relationship focused issues in this paper. In 2020/21, there was a transition from cold to warm Asia. surface air (SAT) suddenly changed with long duration. period lasted 21 November 2020 11 January 2021, while 19 28 February 2021. And 12 18 2021.There were significant differences atmospheric circulations between periods...
In July and August 2024, two rare consecutive stratospheric sudden warming (SSW) events, SW07 SW08 occurred in the Southern Hemisphere. These events were marked by a rapid Antarctic temperature increase of nearly 17°C at 10 hPa within few days significant deceleration polar vortex (SPV). particular, represents earliest event recorded satellite era. Both meet criteria for minor SSWs set new historical records. The analysis reveals that planetary wave anomalies, dominated nonlinear...
Abstract In July and August 2024, two consecutive stratospheric sudden warming (SSW) events (termed SW07 SW08) occurred over Antarctic, both featuring a rapid 17°C temperature rise at 10 hPa significant polar vortex (SPV) deceleration. the earliest winter time of year recorded in satellite era (1979 to present). The study found that, strong blocking highs affected via nonlinear planetary wave prior SW07, substantial sea ice loss Antarctic Ross Sea Amundsen likely created favorable conditions...
Abstract The urban barrier effect is one possible physical mechanism by which the urbanization alters spatial distribution of cloud‐to‐ground (CG) lightning activity in a city. There gap preceding research on an to alter patterns CG Beijing, and morphology does not receive enough attention as important influencing factor. By combining location data, ground meteorological datasets, we identify from perspective Beijing during 2010–2017. Analysis typical thunderstorm 13 July 2017 revealed that...
Abstract The quantitative relationship between the channel‐base current and associated low‐frequency magnetic field ( B ‐field) during early stage of rocket‐triggered lightning was examined based on experiments numerical simulation. There is a good correlation pulse corresponding ‐field in terms amplitude duration. In specific, duration approximately proportional to that for precursors initial upward leaders; as amplitude, linear more apparent leaders when compared precursors, with ratio 1.7...
Abstract. The effect of urban barriers may have a significant impact on the patterns thunderstorm processes and lightning activity, but there is still lack comprehensive mechanical explanations. observational analysis carried out in this study found that cloud-to-ground (CG) lighting activity tends to cluster around outer boundaries mega cities, while, opposite, CG gathers within small-sized city. When squall line originating from type mesoscale convective system (MCS) known as '0713' passed...
Abstract Based on the ERA-Interim reanalysis data, a sub-seasonal oscillation of sea surface temperature (SST) and its characteristics are revealed in Southern Indian Ocean from December to February (DJF). The results Empirical Orthogonal Function (EOF) analysis show that first two dominant modes SST spatial distribution Southwest-Northeast direction dipole (SIOD) triple (SIOT) respectively. research shows intensity zonal Mascarene High conducive formation SIOD (SIOT). air-sea interaction...
