Pollen brings seasonal misery to millions of Americans, but it serves a critical purpose: fertilizing many kinds of plants, including food crops.
If the forecast system works, African cities need significant on the ground support.
Could South Africa’s recent flooding have been foreseen? It has long been a challenge for scientists and engineers around the world.
Weather forecasting is complex and challenging. The process entails three steps: observation, analysis and communication.
A satellite view on the night of Dec. 15, 2021, at the same time tornadoes were reported in Iowa.
Forecasters described it as a ‘historical weather day.’ An atmospheric scientist who was at the heart of the storms explains what happened.
Tiny changes, like a butterfly’s wing flapping, can be amplified downstream in a chaotic system.

Part of the 2021 Nobel Prize in Physics was awarded for work modeling Earth’s climate using its chaotic, complex weather. To scientists, chaos lies in the gray zone between randomness and predictability.

Some so-called superforecasters are claimed to have predicted the course of the pandemic better than scientific experts.

New Orleans has about a 40% chance of getting hit by a tropical storm in any given year. Here’s how heat, winds and the shape of the seafloor raise the hurricane damage risk.
As the old joke goes, it’s difficult to make predictions, especially about the future.

Can political prediction models pick the election winner better than the polls, the weather or Washington’s football team?
Many of the more formal models for predicting the pandemic try to understand why changes happen – but often it can be more accurate to ignore the reasons and simply look at the data.
The global financial crisis taught us recoveries needn’t be V-shaped.

Puerto Rico’s January earthquakes came after many foreshocks and have been followed by numerous aftershocks. Scientists are studying these sequences to improve earthquake forecasting.
Queenslanders have taken to the water in the face of record-breaking heat.
The summer forecast from the Bureau of Meteorology predicts a hot, dry summer.

The warm period will occur even on top of regular climate change.
Brrr! It’s cold in here!
Winter is here, and many farmers are still waiting on their ‘autumn break’ of heavy rain. Unfortunately, it looks like it will be a dry, warm winter – although the snow season will likely be good.
Images created by NASA with satellite data helped the U.S. Department of Agriculture analyze outbreak patterns for southern pine beetles in Alabama, in spring 2016.
Big data open-access publishing and other advances offer ecologists the ability to forecast events like pest outbreaks over days and seasons rather than decades. But scholars need to seize this opportunity.
It’s exam time. Research suggests that while some students will be pleasantly surprised by how they did on exams, a larger group will falsely believe they did much better on their exams than they did.
Research shows that many students are excessively optimistic about course grades. Those with a stronger sense of personal control are also less likely to receive the grades they expect.
