Influence of the Maritime Continent on the Boreal Summer Intraseasonal Oscillation

Journal of the Meteorological Society of Japan. Ser. II, 2010
The effect of the Maritime Continent (MC) on the propagation characteristics of the boreal summer intraseasonal oscillation (ISO) over the Indo-western Pacific region were investigated by performing high-resolution (T159) atmospheric general circulation model (AGCM) simulations that remove and retain the MC. The most significant difference, as revealed

Diagnosing ocean feedbacks to the BSISO: SST-modulated surface fluxes and the moist static energy budget [PDF]

, 2019
The oceanic feedback to the atmospheric boreal summer intraseasonal oscillation (BSISO) is examined by diagnosing the sea surface temperature (SST) modification of surface fluxes and the moist static energy (MSE) on intraseasonal scales. SST variability

Simulation of the intraseasonal variability over the Eastern Pacific ITCZ in climate models [PDF]

, 2012
During boreal summer, convective activity over the eastern Pacific (EPAC) inter-tropical convergence zone (ITCZ) exhibits vigorous intraseasonal variability (ISV). Previous observational studies identified two dominant ISV modes over the EPAC, i.e., a 40-

Indo‐Pacific Ocean response to atmospheric intraseasonal variability: 2. Boreal summer and the Intraseasonal Oscillation [PDF]

Journal of Geophysical Research: Oceans, 2004
The basin‐wide response of the Indo‐Pacific Ocean to atmospheric forcing associated with the Intraseasonal Oscillation (ISO) is examined using an ocean general circulation model forced by canonical ISO conditions constructed from observations. The results show that the imposed ISO forcing induces ocean variability that both is local to the region of ...

Intraseasonal Variability of Air Temperature Over East Asia in Boreal Summer

Frontiers in Earth Science, 2017
The intraseasonal oscillation (ISO) of atmospheric temperature at 2 m over East Asia (EA) in boreal summer is investigated through NCEP-NCAR reanalysis data for the period of 1979–2013.

Influence of Intraseasonal Variability on the Development of Monsoon Depressions

Geophysical Research Letters, 2021
Previous studies showed that the activity of monsoon low‐pressure systems (LPS), which produce a large fraction of the South Asian monsoon's total rainfall, is modulated by intraseasonal variability.

Is there regime behavior in monsoon convection in the late 20th century? [PDF]

, 2010
Mixture model techniques are applied to a daily index of monsoon convection from ERA‐40 reanalysis to show regime behavior. The result is the existence of two significant regimes showing preferred locations of convection within the Asia/Western‐North ...

Characteristic Analysis of the 10–30-Day Intraseasonal Oscillation over Mid-High-Latitude Eurasia in Boreal Summer

Atmosphere, 2023
The aim of this study is to investigate the characteristics of the intraseasonal oscillation (ISO) with a 10–30-day cycle over mid-high-latitude Eurasia during boreal summer.

Ocean Rossby waves as a triggering mechanism for primary Madden-Julian events [PDF]

, 2012
The Madden–Julian Oscillation (MJO) is sporadic, with episodes of cyclical activity interspersed with inactive periods. However, it remains unclear what may trigger a Madden–Julian (MJ) event which is not immediately preceded by any MJO activity: a ...

Simulation of boreal summer intraseasonal oscillations in the latest CMIP5 coupled GCMs [PDF]

Journal of Geophysical Research: Atmospheres, 2013
AbstractThe simulation of the boreal summer intraseasonal oscillation (BSISO) has been analyzed in the historical run of the 32 models, which participated in the Coupled Model Intercomparison Project phase5 (CMIP5), and it is shown that the current state‐of‐the‐art general circulation models (GCMs) still have difficulties to properly simulate the BSISO.
