Tropical and mid-latitude teleconnections interacting with the Indian summer monsoon rainfall: a theory-guided causal effect network approach [PDF]
Earth System Dynamics, 2020 The alternation of active and break phases in Indian summer monsoon (ISM) rainfall at intraseasonal timescales characterizes each ISM season. Both tropical and mid-latitude drivers influence this intraseasonal ISM variability.

Diversity of the Boreal Summer Intraseasonal Oscillation [PDF]
Journal of Geophysical Research D: Atmospheres, 2021 AbstractBoreal summer intraseasonal oscillation (BSISO) profoundly impacts Northern Hemisphere monsoon onsets and breaks, tropical cyclones, and many climate extremes. BSISO exhibits more complex propagation patterns than the dominant eastward propagation of the Madden‐Julian Oscillation.

Ocean Heat Content and the Intraseasonal Oscillation [PDF]
Geophysical Research Letters, 2019 AbstractIntraseasonal sea surface temperature anomalies generally cool during the convectively active phase of the intraseasonal oscillation in the Indian Ocean, but the behavior of intraseasonal ocean heat content anomalies is quite different. This is demonstrated using satellite observations and ocean reanalysis data.

Intraseasonal oscillation enhancing C5 typhoon occurrence over the tropical western North Pacific
Geophysical Research Letters, 2017 This study reveals that the atmosphere‐ocean coupled intraseasonal oscillation (ISO) enhances the occurrence frequency of Category 5 (C5) typhoons in the western North Pacific (WNP).

Frontiers in Earth Science, 2023 The Daily Tropical Cyclone Probability (DTCP), defined as the probability of tropical cyclone occurrence within 500 km of a location in 1 day, is proposed and used in evaluating subseasonal to seasonal (S2S) predictions from the subseasonal to seasonal ...

Frontiers in Environmental Science, 2022 This paper studies the interdecadal transition of interannual variability of summertime intraseasonal rainfall (SIR) over South China (SC). It is found that after the mid-1990s (1995/96), the interannual oscillation of SIR over SC has significantly ...

Intraseasonal Drivers of the 2018 Drought Over São Paulo, Brazil
Frontiers in Climate, 2022 Dry conditions occurred over São Paulo state (southeastern Brazil) from February to July 2018, causing the driest semester in 35 years. Socioeconomic impacts included a record number of fire spots, most adverse conditions to pollutant dispersion in 3 ...

Multiscale interactions driving the devastating floods in Henan Province, China during July 2021
Weather and Climate Extremes, 2023 The rare extreme flooding event in Henan Province, China, during July 2021 (referred to as the “21.7” flooding event) was attributable to persistent heavy rainfall boosted by an enhanced moist southeasterly flow and substantial moisture convergence ...

The skeleton of tropical intraseasonal oscillations [PDF]
Proceedings of the National Academy of Sciences, 2009 The Madden–Julian oscillation (MJO) is the dominant mode of variability in the tropical atmosphere on intraseasonal timescales and planetary spatial scales. Despite the primary importance of the MJO and the decades of research progress since its original discovery, a generally accepted theory for its essential mechanisms has remained ...

A multiscale model for tropical intraseasonal oscillations [PDF]
Proceedings of the National Academy of Sciences, 2004 The tropical intraseasonal 40- to 50-day oscillation (TIO) is the dominant component of variability in the tropical atmosphere with remarkable planetary-scale circulation generated as envelopes of complex multiscale processes. A new multiscale model is developed here that clearly demonstrates the fashion in which planetary-scale circulations sharing ...
