Madden Julian Oscillation (MJO) based on its propagation through the maritime continent can be divided into two types, namely MJO-C (Crossing) and MJO-B (Blocked) as evidenced by spatial diagram of Hovmöller OLR anomaly. This study aimed to determine effect MJO variations, sea surface temperature rainfall in Indonesian region period 1998 2015. The data used this are reanalysis models including ...

13 The Madden Julian Oscillation (MJO) was shown to a ect both present-day Sudden Strato14 spheric Warming (SSW) events in the Arctic, and their future frequency under global 15 warming scenarios, with implications to the Arctic Oscillation and mid-latitude extreme 16 weather. This work uses a dry dynamic core model to understand the dependence of SSW 17 frequency on the amplitude and longitudi...

The Madden–Julian oscillation (MJO) has been demonstrated to play a role in tropical cyclone (TC) activity around the globe in a number of recent studies. While the impact of the MJO on TCs in the Atlantic basin since themid-1970s has beenwell documented, a newly developed 107-yr-long index for theMJO allows for additional analysis of the impacts of theMJO onAtlantic TC activity. TC activity in...

In this study, we model extreme rainfall to study the high events in province of South Sulawesi, Indonesia. We investigated effect El Nino Oscillation (ENSO), Indian Ocean Dipole Mode (IOD), and Madden–Julian (MJO) on events. also assume that a location are affected by other nearby locations. Using data from results showed related IOD MJO.

There are rich variabilities in the global atmosphere and climate system on intraseasonal time scale. This review article focuses Madden-Julian Oscillation (MJO), which is dominant mode of tropical variability. The MJO has a tremendous impact represents major source skill for subseasonal to seasonal predictions. Our knowledge been advanced recent decades, but challenges remain understanding, si...

The long-term goal of this project is to developing a seamless weather and climate prediction system that has capability to predict accurately both weather phenomena such as tropical cyclones (TC) and other extreme weather events and longer climate-scale phenomena such as the Madden-Julian Oscillation (MJO) and the El Nino-Southern Oscillation (ENSO). Organized moist convections in the tropical...

Abstract The quasi‐biennial oscillation (QBO) impacts the Madden‐Julian Oscillation (MJO) activity with a stronger MJO in QBO easterly (QBOE) than westerly (QBOW) winters. However, this relationship is poorly represented current generation climate models. For first time, paper applies stratospheric zonal‐mean nudging subseasonal prediction system to capture it. Two strong cases QBO‐neutral wint...

The influence of the Madden-Julian Oscillation (MJO) on surface air temperature over Iran is examined using daily data from meteorological stations 1979 to 2015. Composites anomalies are positive in MJO phases 1 and 8 negative 3–4 with broader region tendencies also 2 7, 5–6. This variability associated horizontal advection, whereby southerly (northward) winds act heat northerly (southward) coo...

This work is being done in conjunction with other observational and modelling research aimed at improving the representation of the Madden-Julian Oscillation (MJO) in global models. In combines remote sensing and in-situ observations made from the RV-Revell during legs 2 & 3 of the DYNAMO experiement to help characterize vertical transport through the boundary layer and to build statistics of t...
