Geophysical Research LettersThe Arctic Oscillation (AO) is the most significant mode of sea level pressure (SLP) anomalies in the Northern Hemisphere, exhibiting significant multiple‐timescale variability from synoptic to decadal.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

Transport and mixing of chemical air masses in idealized baroclinic life cycles
, 2007 The transport, mixing, and three- dimensional evolution of chemically distinct air masses within growing baroclinic waves are studied in idealized, high- resolution, life cycle experiments using suitably initialized passive tracers, contrasting the two ...

The influence of solar wind on extratropical cyclones – Part 2: A link mediated by auroral atmospheric gravity waves? [PDF]
Annales Geophysicae, 2009 Cases of mesoscale cloud bands in extratropical cyclones are observed a few hours after atmospheric gravity waves (AGWs) are launched from the auroral ionosphere.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the statistical characteristics of recurving tropical cyclones (TCs) over the western North Pacific (WNP). We find that recurving TCs are, on average, 38% stronger than non‐recurving TCs, owing to longer ocean exposure, fewer landfalls, and passage through warmer, more favorable thermal environments.

Detection and global climatology of two types of spatio-temporal clustering of extratropical cyclones [PDF]
Weather and Climate DynamicsThe swift succession of multiple extratropical cyclones during a short period of time is often associated with weather extremes and characterised by a strong atmospheric jet and enhanced baroclinicity.

Weather, EarlyView.Abstract While the North Atlantic’s five‐century hurricane history is among the most complete globally, the earliest centuries are poorly documented in the written record. This study reassesses a subset of sixteenth to seventeenth‐century tropical cyclones (TCs) through a systematic review of archival evidence, mainly from Spain’s colonial archive, the

Extratropical cyclones – a forecaster's perspective [PDF]
Meteorological Applications, 1997 AbstractDespite considerable improvements in numerical models in recent years, weather events associated with extratropical cyclones continue to present forecasters with a challenge. For most cyclogenesis events model forecasts display, at the least, subtle errors in track and intensity of the system.

Weather, EarlyView.This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.

Predictability and dynamics of potential vorticity streamers and connections to high impact weather [PDF]
, 2012 Narrow potential vorticity (PV) intrusions across the tropopause (PV streamers) are interconnected with surface high- and low- pressure systems and frequently present during high-impact weather in the mid-latitudes. They often form during the breaking of
