Predicting the weather in a warming world

The Economist  

IN RECENT WEEKS, extreme heat, floods and storms have smashed records and caused devastation around the world. How are meteorologists gearing up to face the enormous challenge of predicting the weather in a warming world? Andrew Charlton-Perez, at the University of Reading in Britain, explains how weather forecasts are made—and why meteorology is such a complicated science. She asks Sam Levang, the chief scientist at Salient Predictions, how artificial intelligence can play a role in improving predictions of the weather. Rachel also visits the European Centre for Medium-Range Weather Forecasts’s data centre in Bologna, Italy, to understand how a combination of technological approaches will be required to make weather forecasting fit for the 21st century.

How to predict record-shattering weather events

Hindustan Times  

The heatwave that struck parts of North America’s Pacific coast in 2021 propelled temperatures in Lytton, a village in British Columbia, to 49.6°C—4.6° higher than the previous record. That makes it much more complex.” To try to understand what had happened, Dr Thompson’s team simulated British winters between 1981 and 2015 many thousands of times, and looked at the spread …

The Business of Weather Forecasting is Heating Up in India And A Moody Monsoon Could be the Catalyst

News 18  

Earlier this month, when the India Meteorological Department declared an early arrival of the southwest monsoon, there was an obvious sense of relief. So, if the private forecasters can complement it, rather than compete, it will probably help to meet the common goal of ensuring that the weather forecast reaches the last mile.” The senior scientist was also quick to …
