As a result, radar can be an exceptional tool in a meteorologist’s arsenal for helping to protect life and property. Meteorologists can use this information to determine specific areas where dangerous weather conditions exist. When the electromagnetic pulse strikes an object such as a raindrop or a snowflake, the wave reflects back to the radar with data that can be analyzed by meteorologists. Weather radar (also known as Doppler weather radar) is an instrument that sends pulses of electromagnetic energy into the atmosphere to find precipitation, determine its motion and intensity, and identify the precipitation type such as rain, snow or hail. That’s why we compiled the most frequently asked questions to create a basic overview of radar technologies, options and benefits. Mild with highest temperatures of 11 to 14 degrees.Weather radar is always a hot topic among our clients. Breezy at times with moderate, occasionally fresh, west to southwest winds. Overall cloudy with limited sunny spells. Drier elsewhere with more isolated drizzle patches. Monday will be a dull or damp day for the west and northwest with further outbreaks of rain or drizzle. Staying mild overnight in temperatures of 9 or 10 degrees. Rather misty in places will some hill fog. Becoming quite windy too in mostly fresh southwest winds, with strong winds at times in the west and north. TonightĬloudy or overcast tonight with outbreaks of light rain or drizzle, mainly affecting Connacht and Ulster. Mild with highest temperatures of 10 to 14 degrees. West to southwest winds will increase moderate to fresh in the afternoon, becoming windy later in the northwest. More widespread patchy rain or drizzle will develop in Atlantic counties later this afternoon. There may be some spots of drizzle in the west and northwest. This morning will be largely dry under mostly cloudy skies, with the best of any sunny spells today in Munster or Leinster. This service is based on data and products of the European Centre for Medium-range Weather Forecasts (ECMWF). It forecasts the MSLP in hecto Pascals (hPa) for the top of that hour initially in 3 hourly intervals, then 6 hourly. The Mean Sea Level Pressure (MSLP) is direct model output from Numerical Weather Prediction models but is a guideline only. Minus zero (-0) indicates values between 0 to -0.5☌. It forecasts air temperature on land and over sea in ☌ for the top of each hour, 3 hourly and finally 6 hourly intervals up to 7 days. The temperature is direct model output from Numerical Weather Prediction models but is a guideline only. However, in the text forecast below, it is described as where it is blowing from. The wind arrow tip points in the direction the wind is blowing and the tail length indicates wind strength. It forecasts the strength of the wind (in knots and km/h) at 10m for the top of each hour, in hourly, then 3 hourly and finally 6 hourly intervals up to 7 days. The wind is direct model output from Numerical Weather Prediction models but is a guideline only. This service is based on data and products of the European Centre for Medium-range Weather Forecasts (ECMWF) It forecasts how much rain will fall (in mm) hourly during the previous hour (accumulations), then in 3 hourly and finally 6 hourly accumulations up to 7 days. Rain refers to precipitation, which can be rain, sleet or snow. The rainfall forecast is direct model output from Numerical Weather Prediction models but is a guideline only. Met Éireann forecasters manually produce the weather icons for midday and midnight to reflect the predicted major weather type for these times. Images are a combination of Met Éireann and Met Office radar in Dublin, Shannon,īelfast and Wales, when available. They are artefacts (false echoes) of rainfall radar systems and should be Dublin), Bright Bands and spokes may also be They are red but change to orange and then yellow after a period, then disappear. Lightning strikes, when they occur, are displayed as a cross.
