Equatorial upper-ocean dynamics and their interaction with the West African monsoon [PDF]
Zonal wind anomalies in the western equatorial Atlantic during late boreal winter to early summer precondition boreal summer cold/warm events in the eastern equatorial Atlantic (EEA) that manifest in a strong interannual Atlantic cold tongue (ACT ...

Diagnosing ISO Forecast from GloSea5 Using Dynamic-Oriented ISO Theory
A Madden–Jillian oscillation (MJO) and boreal summer intraseasonal oscillation (BSISO) are important climate variabilities, which affect a forecast of weather and climate.

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

Boreal summer sub-seasonal variability of the South Asian monsoon in the Met Office GloSea5 initialized coupled model [PDF]
Boreal summer sub-seasonal variability in the Asian monsoon, otherwise known as the monsoon intra-seasonal oscillation (MISO), is one of the dominant modes of intraseasonal variability in the tropics, with large impacts on total monsoon rainfall and ...

Vertical Vorticity Structure Associated with the Boreal Summer Intraseasonal Oscillation: Barotropic or Baroclinic? [PDF]
This study investigates the reason why the barotropic vorticity structure prevails vertically in response to the enhanced convection associated with the boreal summer intraseasonal oscillation over the central Indian Ocean. The relative vorticity tendency analysis for a 2.5-layer simplified model demonstrates that the barotopic vorticity structure is ...

Weather types across the Maritime Continent: From the diurnal cycle to interannual variations
Six weather types (WTs) are computed across the Maritime Continent during austral summer (September--April) using cluster analysis of unfiltered, daily, low-level winds at 850 hPa, by a k-means algorithm.

Vertical Moist Thermodynamic Structure of the Madden–Julian Oscillation in Atmospheric Infrared Sounder Retrievals: An Update and a Comparison to ECMWF Interim Re-Analysis [PDF]
The large-scale vertical moist thermodynamic structure of the Madden–Julian oscillation (MJO) was documented using the first 2.5 yr (2002–05) of version 4 atmospheric specific humidity and temperature profiles from the Atmospheric Infrared Sounder (AIRS).
