Researchers Develop Wet Weather Warning System
Researchers develop a new technique to improve the long-range accuracy of summer weather forecasts, according to UK News on December 19, 2017.
Scientists have found a strong link between the sea temperature in March and April and the position of the jet stream in July and August.
Current seasonal models for weather over Europe are able to predict long-term forecasts, however, have failed to do so for rainfall.
A paper published in the Proceedings of the National Academy of Sciences USA, the team explained that the results have an “immediate application to empirical forecasts of summer rainfall for the United Kingdom, Ireland, and northern France”.
The new approach has the potential for a range of high value applications ranging from tourism to agriculture, construction, and retail.
Dr Albert Osso, a researcher with the National Centre of Atmospheric Science at Reading University, told the BBC: “We found a strong link between sea surface temperatures east of Newfoundland during the spring and the position of the jet stream and the weather in the UK.”
He added, “What we have seen is that when temperatures are warmer than normal in this area of the ocean, the storms basically move far north and they miss the UK, not all of them, but on average most of the storms are going to miss.”
The development of this procedure, in turn, has the potential to predict summers washouts months before the UK and Ireland get drenched. There are several events that completely rely on the whether such as weddings, barbecues, and countless other weather-reliant activities. The prediction could help them plan and organize the events accordingly.
