Monsoons are weather patterns that bring thunderstorms and heavy rains to hot, dry areas when warm, moist ocean air moves inland. They’re challenging to forecast, especially in a changing climate.
Australia has expansive areas of flat land — usually agricultural land — and it’s over these large, flat areas that tornadoes like to form.
I helped forecast disaster – but nothing prepared for me what happened next.
Extreme heat warnings can help change our dangerous relationship with hot weather.
This summer is likely to be hot and dry, but that’s more down to climate change than miserable spring.
The US is shifting to a new set of climate ‘normals’ – data sets averaged over the past 30 years. But normal is a relative concept in a time of climate change.
It has only been in the past century that weather prediction on Earth has advanced enough to work two weeks in advance. Predicting space weather, however, is only reliable an hour in advance.
With the onset of spring come thunderstorms, and sometimes tornadoes. Learn how these systems form and why night tornadoes are especially deadly.
Ramping up fossil power sources is no longer a good option in an energy-supply crisis. Bring in the weather forecasters.
At the start of the cyclone season in the Pacific, weather forecasters are changing their warnings to focus less on weather information and more on the damage expected from an impending storm.
Hurricane and tornado winds spin in circles, but there’s another, equally dangerous storm type where winds barrel straight ahead. They’re called derechos, and are most common in summer.
Massive cyclone that hit India and Bangladesh could have been so much worse.
More than one million weather observations were made by aircraft each day in 2019. Since the pandemic started, these have dropped by 90%.
In the Southeast US, tornadoes strike at night more often than in other regions. This poses special challenges for getting early warnings to the public.
How science has been used to predict wind and rain for over 1,000 years.
Some parts of Australia have enjoyed excellent rainfall this year, but others have not. Drought relief is still slow and patchy.
Earth’s biggest rivers are streams of warm water vapor in the atmosphere that can cause huge rain and snowfall over land. Climate change is making them longer, wetter and stronger.
Humans are not very sensitive to changes in air pressure, but they can have a big effect on the weather.
Not all droughts are the same and South Africa needs to have a targeted approach to each type.
Today’s three-day weather forecast is as accurate as a 24-hour forecast in the 1990s. But floods are still particularly tricky to pin down.
