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 (

Vertical Moist Thermodynamic Structure and Spatial–Temporal Evolution of the MJO in AIRS Observations [PDF]

, 2006
The atmospheric moisture and temperature profiles from the Atmospheric Infrared Sounder (AIRS)/Advanced Microwave Sounding Unit on the NASA Aqua mission, in combination with the precipitation from the Tropical Rainfall Measuring Mission (TRMM), are ...

Tropical and mid-latitude teleconnections interacting with the Indian summer monsoon rainfall: a theory-guided causal effect network approach [PDF]

, 2020
The alternation of active and break phases in Indian summer monsoon (ISM) rainfall at intraseasonal timescales characterizes each ISM season. Both tropical and mid-latitude drivers influence this intraseasonal ISM variability.

Deep learning for bias correction of MJO prediction [PDF]

Nature Communications, 2021
AbstractProducing accurate weather prediction beyond two weeks is an urgent challenge due to its ever-increasing socioeconomic value. The Madden-Julian Oscillation (MJO), a planetary-scale tropical convective system, serves as a primary source of global subseasonal (i.e., targeting three to four weeks) predictability.

Real-time extraction of the Madden-Julian oscillation using empirical mode decomposition and statistical forecasting with a VARMA model [PDF]

, 2008
A simple guide to the new technique of empirical mode decomposition (EMD) in a meteorological-climate forecasting context is presented. A single application of EMD to a time series essentially acts as a local high-pass filter.

MJO Initiation in the Real-Time Multivariate MJO Index

Journal of Climate, 2013
Abstract Madden–Julian oscillation (MJO) initiation in the real-time multivariate MJO (RMM) index is explored through an analysis of observed case studies and composite events. Specific examples illustrate that both the dates of MJO initiation and the existence of the MJO itself can vary substantially among several well-known MJO indices,

Response of the West African Monsoon to the Madden–Julian Oscillation [PDF]

, 2009
Observations show that rainfall over West Africa is influenced by the Madden-Julian Oscillation (MJO). A number of mechanisms have been suggested: 1) forcing by equatorial waves; 2) enhanced monsoon moisture supply; and 3) increased African easterly wave

Study of ionic liquids (AIL and PIL) viscosity and its functional groups under heat treatment on cutting tool surface using fourier-transform infrared spectroscopy (FTIR) [PDF]

, 2020
This study was conducted to investigate the efficiency of Minimum Quantity Lubrication (MQL) technique by using Modified Jatropha Oil (MJO) bio-based lubricant with the presence of 10% Ammonium Ionic Liquid (MJO+AIL10%) and 1% Phosphonium Ionic Liquid ...

Influence of the Madden-Julian Oscillation on upper tropospheric humidity [PDF]

, 2002
Variations of upper tropospheric humidity (UTH) and cold cloud in the tropics reveal coherent changes that propagate eastward from the Indian Ocean into the Pacific. The coherence of UTH is high at periods of 30–90 days along the equator.

Energetic processes regulating the strength of MJO circulation over the Maritime Continent during two types of El Niño

Atmospheric and Oceanic Science Letters, 2018
The zonal shift of SST warming patterns associated with the eastern Pacific (EP) and central Pacific (CP) El Niño leads to a significant contrast in MJO strength over the Maritime Continent.
