of cyclones.  What is a tropical cyclone? Tropical cyclones are large rotating storms that form over the tropical oceans. They usually develop when sea surface temperatures are at least 26.5 degrees Celsius and get their extreme energy from warm, moist ocean air. Also known as hurricanes in the North Atlantic

, increase North Atlantic hurricane activity, and affect winter rainfall over Europe. In addition, it is likely there would be rapid climate change if SRM were terminated in an uncontrolled manner. Much more research is needed to understand all the potential benefits and drawbacks associated

has been influenced by a very active jet stream, which is driving unsettled weather across the north and west of the UK. The remnants of Hurricanes Humberto and Imelda have interacted with the jet stream, accelerating its flow and contributing to the rapid intensification of the low pressure

natural variability and climate change. It has already been demonstrated that skillful multi-year predictions of Atlantic hurricane frequency can be produced (Smith et al. 2010). Much more remains to be done to exploit the regional information in decadal forecasts and indeed in climate predictions

While the UK bakes, eyes are also on the Eastern Pacific, where Tropical Storm Erick is developing. It’s expected to strengthen into a hurricane by Wednesday and make landfall in southwestern Mexico on Thursday. Impacts include: Heavy rain Strong winds Storm surge While this system won’t affect

knots Track forecast errors were low and skill scores very high for forecasts for Hurricane Helene. The landfall location was very well predicted. Isaac (10L) 26-30 September 968 mb, 90 knots The first forecast for Isaac was a little fast, but later forecasts had very low track forecast errors
