Topography plays a key role in the development of extreme rainfall events in Jakarta, Indonesia. The IOD and MJO play a greater role in these extremes than ENSO.

Extreme daily accumulated rainfall is greater when convection is organised, because convection is localised in relatively fixed locations once it’s organised, which increases the accumulated extreme rain over long timescales.
A range of international workshops, a new citizen science app and some significant research has made the past four months a busy time for the Extreme Rainfall research program.
Under future global warming, models shows increases in the wettest day of the season or year exceeds the range of changes explained by natural variability in most land areas.
Severe thunderstorms across Queensland on Sunday, October 21, provided the first opportunity for citizen scientists to report severe weather using the WeatheX app.
If you are a stormchaser or just someone who loves the theatre of wind, lightning, heavy rain and hail when a storm whips through, then you are perfectly placed to help climate science with the new WeatheX app.
The Extreme Rainfall Research Program of the Centre of Excellence for Climate Extremes (CLEX) held a workshop on October 4 at the University of New South Wales (Sydney). There were 30 participants representing the CLEX nodes, Bureau of Meteorology, CSIRO, NSW Office of Environment and Heritage and National Centre for Atmospheric Research.
The Central American mid‐summer drought (MSD) is the decline in rainfall during the middle of the wet season over Central America, which has been shown to have strong effects on agriculture and bushfires in Costa Rica. The Madden–Julian oscillation (MJO) has been shown to influence Costa Rican rainfall on intra‐seasonal time scales, and therefore may be important to the MSD. This research aims to find the connection between the MJO and MSD.
The past four months since out last newsletter has been tightly packed with the official launch of CLEX, the legacy event for ARCCSS and an acceleration in important research across all of our programs.
The Extreme Rainfall Research Program has put personnel in place and is working on research into how extreme rainfall is represented in models.
