“…In the present work, we carry out the study from this hypothesis, since this mechanism is more consistent with the fact that the IASM onset presents a distinct southeastward-propagating pattern (Tanaka 1994;Zhang and Wang 2008). In fact, the same particular phenomenon in which the onset of the summer monsoon always coincides with the arrival of the convectively active intraseasonal oscillation (ISO) has also been noted in some other regional monsoon systems, such as the Indian summer monsoon (e.g., Joseph and Pillai 1988;Ghanekar et al 2010;Zhou and Murtugudde 2014;Bhatla et al 2017;Taraphdar et al 2018), the Bay of Bengal summer monsoon (Li et al 2013), and the South China Sea summer monsoon (e.g., Zhou and Chan 2005;Straub et al 2006;Tong et al 2009;Wu 2010;Kajikawa and Wang 2012;Lin et al 2016).…”

The Madden–Julian oscillation (MJO) often causes the onset of the Indonesian–Australian summer monsoon (IASM) over Indonesia and northern Australia. In the present study, a composite analysis is conducted to reveal the detailed IASM onset process and its air–sea interactions associated with the first-branch eastward-propagating MJO (FEMJO) based on 30-yr ERA-Interim data, satellite-derived sea surface temperature (SST), outgoing longwave radiation (OLR), and SODA3 ocean reanalysis. The results distinctly illustrate the phase-locked relationships among the persistent sea surface warming north of Australia, the FEMJO, and the established westerlies. It is found that the SST to the north of Australia reaches its annual maximum just before the onset of the summer monsoon. The oceanic surface mixed layer heat budget discloses that this rapid warming is primarily produced by the enhanced surface heat flux. In addition, this premonsoon sea surface warming increases the air specific humidity in the low-level troposphere and then establishes zonal moisture asymmetry relative to the FEMJO convection. This creates a more unstable atmospheric stratification southeast of the FEMJO and favors convection throughout the vicinity of northern Australia, which ultimately triggers the onset of the IASM. The results in this study thus may potentially be applicable to seasonal monsoon climate monitoring and prediction.

“…5.d), especially in southern regions. This is agreed with previous studies that high OLR values indicate clear skies and dry conditions, while low OLR values suggest the presence of clouds and increased moisture content in the atmosphere (Adhikari et al, 2022;Fontaine et al, 2008;Ghanekar et al, 2010). Moreover, it confirmed the rainfall pattern variation of early and late-onset years as mentioned previously.…”

This study delves into the intricate connection between Mainland Indochina Southwest Monsoon (MSWM) onset dates and tropical cyclones (TCs) over the Bay of Bengal (BOB) and Arabian Sea (ABMS). Utilizing datasets like IBTrACS, ERA5 reanalysis, and CHRIPS daily rainfall data, the research highlights the influence of TCs on monsoon onset, emphasizing sea surface temperatures and rainfall intensity. The bimodal distribution of cyclones during early and late-onset years is noted, characterizing MSWM onset by the April-June TC count. Significant correlations emerge between cyclone frequency, monsoon onset dates, SST, and rainfall patterns. Cyclones impact agriculture, water resources, and disaster preparedness in monsoon-dependent regions. Employing a robust methodology, the study reveals a complex relationship between TCs and monsoon onset, with early-onset years experiencing higher TC numbers. Additionally, the research explores the impact of El Niño–Southern Oscillation (ENSO), associating positive phases with late monsoon onset and negative phases with early onset and increased rainfall. The findings underscore TCs' multifaceted role in shaping the monsoon, offering insights into intricate climate variables and cyclone dynamics in the northern Indian Ocean.
