CONFIDENCE- Pilot report of ash at FL380 here at 13/1430Z. Not supported model output and not discernible on satellite imagery due to frontal (meteorological) cloud. Seems unlikely at that height also. LOW CONFIDENCE- Low confidence in ash in this ellipse due to obscuration by meteorological cloud. Ash suggested by model output only in this region. © Crown copyright Met Office

smoothed power versus range of real radar data contaminated with RFI. • Presence of interference pulses from several sources is visible from 40km, where the power level of the received echoes is below the RFI.

spring on record. Mean temperatures for spring were just ahead of the previous record of 2024, whilst the record sunshine hours surpassed those of the Covid spring of 2020. The late burst of Atlantic mobility was sufficient to bring monthly rainfall totals across parts of the north Midlands, northwest

14.5 °C, with fog in some central and southern counties, the 11th was mainly dry with just patchy light rain for the north, and it brightened up across the south-east during the afternoon. The 12th was rather cloudy, but the cloud tended to thin and break from most parts away from western coastal

  The representation of fog, cloud and rain processes in regional modelling is of fundamental importance for both NWP and climate, particularly at “convective” resolving scales. This session will include talks and discussion covering; fog and visibility,  microphysics (both cloud and aerosol), aerosol-cloud

in satellite imagery extending northeast from Katla, although now partially obscured by upper cloud layers. This position verifies well with model forecasts.

1300 UTC Jan 27 2016 annotated satellite image Issued 1350 UTC on Wednesday 27 Jan 2016 LOW CONFIDENCE- Ash may extend further west in Denmark Strait but cloud cover means it cannot be discerned by satellite imagery. EXERCISE HIGH CONFIDENCE- VA clearly discernible in satellite imagery. Verified
