  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. Smoothed power vs. range plot of the 54 pulses of the burst at azimuth 324° (V polarization

  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

• Met Office Weather: Showers & sunshine expected midweek

  Wednesday morning will begin with locally heavy rain moving southeast across parts of England and Wales, accompanied by an area of showers pushing southeast. By mid-morning, the rain will clear the far southeast, leaving behind variable cloud cover and scattered showers. Temperatures will be around

• Parallel Suite 43 release notes

  Top level summary of PS43 PS43 introduces atmospheric physics upgrades to both the global and regional NWP models. In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional

• Met Office daily weather: Largely fine and warm weekend

  While some areas will start off cloudy, particularly in the east, conditions are expected to improve as the days progress, offering ideal weather for outdoor events and activities. Saturday will begin with widespread cloud cover across Scotland, England, and eastern Wales, accompanied by hill fog

  . As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. Consequently, the weather in a depression is often cloudy, wet and windy (with winds blowing in an anticlockwise direction around the depression). There are usually frontal systems associated with depressions. Figure
