Application of MJO Simulation Diagnostics to Climate Models [PDF]

, 2014
The ability of eight climate models to simulate the Madden-Julian oscillation (MJO) is examined using diagnostics developed by the U.S. Climate Variability and Predictability (CLIVAR) MJO Working Group.

Influence of Indian Ocean Dipole on Poleward Propagation of Boreal Summer Intraseasonal Oscillations

Journal of Climate, 2008
Abstract The influence of the Indian Ocean dipole (IOD) on the poleward propagation of boreal summer intraseasonal oscillations (BSISOs) is examined using observed datasets. This study finds that coherent (incoherent) poleward propagation of precipitation anomalies from 5°S to 25°N are observed during negative (positive) IOD years ...

Does the Madden-Julian Oscillation influence aerosol variability? [PDF]

, 2008
We investigate the modulation of aerosols by the Madden-Julian Oscillation (MJO) using multiple, global satellite aerosol products: aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7, and aerosol optical thickness (AOT) from ...

A link between tropical intraseasonal variability and Arctic stratospheric ozone [PDF]

, 2013
Previous studies using satellite measurements showed evidence that subtropical upper troposphere/lower stratosphere ozone (O_3) can be modulated by tropical intraseasonal variability, the most dominant form of which is the Madden Julian Oscillation (MJO)

Estimate of the Predictability of Boreal Summer and Winter Intraseasonal Oscillations from Observations

Monthly Weather Review, 2011
AbstractTropical intraseasonal variability (TISV) shows two dominant modes: the boreal winter Madden–Julian oscillation (MJO) and the boreal summer intraseasonal oscillation (BSISO). The two modes differ in intensity, frequency, and movement, thereby presumably indicating different predictabilities.

Tropical intraseasonal oscillations in CFSv2 during Boreal summer and winter

International Journal of Climatology, 2016
ABSTRACTThe simulation of the tropical intraseasonal oscillations (ISOs) by a coupled model in the Indo‐Pacific region is examined in this study. The retrospective forecasts by the Climate Forecast System version 2 (CFSv2) of National Centers of Environmental Prediction for the period 1982–2010 have been analysed and compared with observation.

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. II: Changing ENSO regimes [PDF]

, 2007
Integrations of a fully-coupled climate model with and without flux adjustments in the equatorial oceans are performed under 2×CO2 conditions to explore in more detail the impact of increased greenhouse gas forcing on the monsoon-ENSO system.

Influence of the boreal summer intraseasonal oscillation on temperature and precipitation in South Korea

Atmospheric Science Letters
The boreal summer intraseasonal oscillation (BSISO) is a major mode of sub‐seasonal variability that regulates the summer climate in East Asia. This study investigates the four possible effects of two different time‐scale BSISOs on temperature and ...

Enhanced Pacific Northwest heat extremes and wildfire risks induced by the boreal summer intraseasonal oscillation

npj Climate and Atmospheric Science
The occurrence of extreme hot and dry summer conditions in the Pacific Northwest region of North America (PNW) has been known to be influenced by climate modes of variability such as the El Niño-Southern Oscillation and other variations in tropospheric ...
