"After another spell of wet weather along Australia’s east coast, with storms,
heavy rain and flash flooding across Sydney and parts of New South Wales, it is
natural to ask whether our cities are shaping the rainfall that descends upon
them.
This matters because most people now live in cities. If urbanisation changes
rainfall, even slightly, the effects can reach large populations through
flooding, stormwater design, water supply and infrastructure planning.
Satellite data have consistently shown that many cities experience more rain
events than the countryside around them. The usual explanation is that cities
themselves are involved: urban heat, rougher surfaces, aerosols and changed
land cover can all affect how storms develop and where rain falls.
Our new study, published in
Environmental Research Letters, asks a related
question: how much of this data reflects real changes in rainfall, and how much
depends on how we observe it?"
