High humidity, terrain and wind make rain forecasting particularly tricky in the tropics.
The UK is no stranger to drought – especially southern England.
Despite international and national responses to the drought, the situation is dire. The government’s response is a lesson in how not to deal with drought.
Extreme downpours caught people off guard from Las Vegas to Kentucky in July 2022.
Extreme downpours brought deadly flooding to the Appalachian region, just a few weeks after the destructive Yellowstone River flood.
Again, thousands of residents in Western Sydney face a life-threatening flood disaster. Obviously, nature is a major culprit – but other drivers are also at play.
The ongoing humanitarian crisis raises serious questions about future food and water security in the Horn of Africa.
Global warming is changing the high-altitude autumn winds over southeast Australia, which means less rain and trouble for air travel.
Would you trust a weather forecast made by a machine that had learned how weather systems behaved by reviewing thousands of past weather maps?
Clearing alien trees from mountain catchments is a more cost-effective approach to providing water than building and maintaining desalination plants.
New data has revealed rainfall records from as far back as 1677.
By following moisture from the oceans to the land, researchers worked out exactly how three oceans conspire to deliver deluges of rain to eastern Australia.
Tree rings are ‘nature’s weather stations’ and reveal far more of the Daly River’s history than scientific records can.
A weather system called ‘atmospheric rivers’ is causing this inundation. In March last year, an atmospheric river brought 800kg of water vapour over Sydney every second.
Southern Africa’s current above-average rainfall is a climate variability signal - a short-term fluctuation in average wet-season conditions.
A draft plan for Sydney’s water supplies includes expanding desalination and potentially adding highly treated sewage to drinking water. All options must be on the table as the climate warms.
US disasters in 2021 told a tale of two climate extremes. A climate scientist explains why wet areas are getting wetter and dry areas drier.
Extended periods of rain are most likely found in locations where mountains are near oceans.
New climate simulations show that there will be more rain and less snow falling in the Arctic by the end of the century, particularly in the fall and winter.
Some Arctic regions will see more rain than snow decades earlier than previously thought, say scientists.
