Az weatherradar4/11/2023 How is a weather radar created?Īs you already know, the radar station and its radar beams are used to measure the amount of water vapor present in a cloud. Only the use of new types of radar technologies, such as the Doppler radar, made this possible. …that the first weather radar was already built in the early 1940s? However, this type of weather radar could not accurately predict the intensity of the rain or the strength of the thunderstorm or storm. This central computer is responsible for processing all the collected data and using it to create a picture of the general weather situation. These weather stations are linked to each other and transmit the collected data to a central computer. To be able to make a concrete weather forecast and to collect and analyze the data over a large area, many different weather radar stations are required at various locations. What is a weather radar live?Ī weather radar live is a special type of radar that collects and analyzes data on the weather situation. You can also zoom in with your fingers or the mouse wheel. Use the + or – at the top right to zoom in. By finger pressure or mouse click you can move the area on the map. ![]() With the cursor at the bottom left in the center you can view the weather over time. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. This is how the weather radar live works: This service is based on data and products of the European Centre for Medium-range Weather Forecasts (ECMWF).Depending on the intensity, the precipitation appears on the rain radar in the colors blue (weak precipitation), green, yellow, orange (moderate precipitation), red or purple (very heavy precipitation). Thunderstorms and lightning strikes are indicated by a small lightning symbol. 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. ![]() This service is based on data and products of the European Centre for Medium-range Weather Forecasts (ECMWF). 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.
