on observation of the clouds and stars and the behaviour of wild birds to alert them to weather-related hazards and to judge the quality of fishing conditions. They also monitor surface currents in the lake, measuring them with floaters, to determine where fishing conditions are likely to be best. Commonly

as an invasive species which produces pollen after pollen burst. Can we link pollen bursts to people visiting GP surgeries? We should do more on phenology modelling to improve links to health warnings What sort of public health interventions can be done for pollen? People need to know what pollen

forecasting: monitoring CME may not yet be visible in coronagraph so forecaster monitors early warning signs: • Monitor ARs for flares as can be associated with CMEs • Any filaments disappeared? – often associated with CMEs • Type II radio burst? – radio emission at CME shock front • Any coronal

that they are going to be reaching out and actually touching the objects that are so formative in shaping our futures as well as our history. I had cause to reflect on that recently as I travelled through the South Kensington subway bursting at the seams with children enjoying their half term outings. I was on my

2023 in the legend. After the front moved through during the evening and overnight 18 to 19 October, the main rainfall event occurred during the 20th as heavy extensive rain spread back across England and Wales, this including some heavier bursts. The maps below show daily rainfall totals for each day

around 30 to 31 December. Transport disruption continued with flooded railways and fallen trees blocking roads in Wales, while Dumfries and Galloway experienced severe flooding as the River Nith burst its banks. Flooding impacts continued into the New Year period, and in early January included large
