Research brief: Why Melbourne’s worst storms come in lines

September 3, 2021 8:51 am Published by Comments Off on Research brief: Why Melbourne’s worst storms come in lines

It has long been suggested in the literature, and discussed casually by meteorologists, that rainfall in Melbourne often occurs as lines of precipitation. However, this had yet to be quantified. CLEX researchers analysed 15 years of radar data from the Australian Radar Archive, using an objective method to identify and track these ‘linear systems’ based on radar reflectivity, size, and shape characteristics.

UNSW05: Quantification of Continental-Scale shifts in Extreme Precipitation Intensity Across the Globe

August 18, 2021 9:15 am Published by Comments Off on UNSW05: Quantification of Continental-Scale shifts in Extreme Precipitation Intensity Across the Globe

Due to the lack of appropriate historical datasets, quantification of shifts in global extreme precipitation intensity has not been possible so far. This project will use a recently developed long-term global dataset of daily precipitation alongside a dataset of global temperature changes to calculate the CC scaling for broad climatic regions across the globe.

Weather and Climate Interactions Report – April 2021

April 14, 2021 10:39 am Published by Comments Off on Weather and Climate Interactions Report – April 2021

Welcome to the first Weather and Climate Interactions RP report. The new program name is simply a result of rationalising CLEX’s continuing research program under new headings that more clearly delineate the focus of the work we do.

Research brief: Extreme events in SE Australia to increase in frequency by 2100

March 25, 2021 12:01 pm Published by Comments Off on Research brief: Extreme events in SE Australia to increase in frequency by 2100

This paper used statistical techniques to investigate changes in extreme climate events that currently occur, on average, only once every 20 years. These techniques are applied to data related to heat, rainfall, drought and conditions conducive to bushfires and thunderstorms from detailed climate modelling commissioned by NSW and ACT Governments.

Research brief: New global land-based precipitation dataset

February 4, 2021 12:12 pm Published by Comments Off on Research brief: New global land-based precipitation dataset

CLEX researchers have developed a new global land-based daily precipitation dataset called Rainfall Estimates on a Gridded Network - REGEN - aimed at facilitating studies to understand changes and variability in several aspects of daily precipitation distributions, extremes and measures of hydrological intensity.

Research brief: Indian Ocean warming modulates global atmospheric circulation trends

November 27, 2020 3:25 pm Published by Comments Off on Research brief: Indian Ocean warming modulates global atmospheric circulation trends

Using atmospheric model experiments, researchers have shown that the warming of the tropical Indian Ocean relative to the other two tropical ocean basins can effectively control Walker Circulation changes in the Pacific and Atlantic oceans and influence climate far beyond the Indian Ocean region.
