The surface diurnal warm layer in the Indian Ocean during CINDY/DYNAMO [PDF]

, 2014
A surface diurnal warm layer is diagnosed from Seaglider observations, and develops on half the days in the CINDY/DYNAMO Indian Ocean experiment. The diurnal warm layer occurs on days of high solar radiation flux (>80 W m-2) and low wind speed (

Changes in Madden‐Julian Oscillation Precipitation and Wind Variance Under Global Warming

Geophysical Research Letters, 2018
The Madden‐Julian oscillation (MJO) is the leading mode of tropical intraseasonal variability, having profound impacts on many weather and climate phenomena across the tropics and extratropics.

Global Impacts of the Madden-Julian Oscillation

Atmosphere-Ocean
Numerous studies have examined the regional impacts of the Madden-Julian Oscillation (MJO) on land surface air temperature and precipitation, but a global unified picture of the MJO impacts is still lacking. This study provides a global unified picture of the MJO impacts on land surface air temperature and precipitation for both the Northern Hemisphere

Simulated Tropical Troposphere Response to the QBO: Effect of Vertical Resolution, Gravity Waves Parameterization, and Boundary Forcing

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract An intermediate complexity general circulation model is used to isolate the effect of vertical resolution and gravity wave parameterization on the simulated monthly quasi‐biennial oscillation (QBO)‐tropical precipitation linkage. For low vertical resolution, the model is able to simulate QBO in the lowermost stratosphere, and its impact on the

The effect of the Madden-Julian Oscillation on station rainfall and river level in the Fly River system, Papua New Guinea [PDF]

, 2013
The Madden-Julian oscillation (MJO) is the dominant mode of intraseasonal variability in tropical rainfall on the large scale, but its signal is often obscured in individual station data, where effects are most directly felt at the local level.

Elliptical Orbit Representation for the Annual Evolution of the Northern Hemisphere Stratospheric Polar Vortex. Part I: Diagnosing Interannual Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Using a single annual frequency with each year defined from July 1 to June 30 of the following calendar year, this study fits an ellipse to the yearly phase space trajectory of the daily time series of MU (stratospheric mass‐weighted zonally integrated zonal wind at 60°N) and M (total polar stratospheric air mass over 60–90°N) to represent the

A dynamical framework for the origin of the diagonal South Pacific and South Atlantic convergence zones [PDF]

, 2015
The South Pacific Convergence Zone (SPCZ) and South Atlantic Convergence Zone (SACZ) are diagonal bands of precipitation that extend from the equator southeastward into the Southern Hemisphere over the western Pacific and Atlantic Oceans, respectively ...

Influence of Western Pacific Madden–Julian Oscillation on New York City's Record‐Breaking Air Pollution in Early June 2023

Geophysical Research Letters
In early June 2023, New York City (NYC) and other cities in the northeastern US experienced a severe air pollution event. Although reports associated this hazardous pollution event with the smoke from Canadian wildfires, the factors triggering the ...
