"On the first day of winter, southwest Western Australia was pummelled by a
damaging storm. The Bureau of Meteorology (BoM) described it as the most
intense weather system to hit the region in almost 50 years. Although severe
storms can be devastating, they’re also important for delivering rain in a part
of Australia that is drying out.
As the planet continues to warm, climate patterns that were stable for decades
are beginning to shift. This changes the extreme weather events we experience
from day to day.
Long-term historical records help us make sense of recent trends. They give us
a rare chance to see how weather extremes have changed since pre-industrial
times.
In meteorology, atmospheric pressure measures the weight of the air around us,
with sudden drops indicating stormy conditions. Our new study, published in
Climate Dynamics, has reconstructed the longest record of pressure readings
taken multiple times a day in the Southern Hemisphere, tracking severe storms
in Perth from 1830.
Historically, data from this region has been sparse. Our results are a vital
contribution to the World Meteorological Organization’s global network of
long-term monitoring stations.
By consolidating nearly 200 years of daily pressure, temperature and rainfall
observations from Perth, our research reveals new details about the behaviour
of severe storms, and broader weather trends across Australia."
