P118 AERTEL 1 118 Wed 23 Feb 08:41:27 3/8 ATLANTIC JET STREAM CHANGES TO IMPACT ————————————— 22 Feb 2022 20:30 The new research, which was led by Dr Samantha Hallam of the ICARUS Climate Research Centre at Maynooth University, found that the average winter jet stream in the North Atlantic and Eurasia has moved northwards by about 330 kilometres over the past 140 years. This is the equivalent to a northward move of 3 degrees latitude, from 44 degrees north to 47 degrees north, and it centers the average path of the North Atlantic winter jet stream much closer overhead to Ireland. s TV LISTINGS 182 TRAVEL RTE1 500 Next Weather Sport Headlines

The path of the jet stream is influenced by differences in air temperature and air pressure between the arctic regions and the Equator. The fact that the increases in temperatures caused by climate change have, so far, been more significant at the poles than at the equator means that average temperature differences between both regions are slowly reducing. s TV LISTINGS 182 TRAVEL RTE1 500 Next Weather Sport Headlines

The study, published this week in the peer-reviewed scientific journal, Climate Dynamics, is the longest regional study of the northern hemisphere jet stream. s TV LISTINGS 182 TRAVEL RTE1 500 Next Weather Sport Headlines

Lead author of the paper, Dr Hallam, said: "Significant increases in winter jet latitude and speed are observed over the North Atlantic and Eurasia which is consistent with the decreasing temperature and increasing pressure gradients observed between the equator and the Arctic over the period. s TV LISTINGS 182 TRAVEL RTE1 500 Next Weather Sport Headlines
