The weather radars are of the type Dopplers. These it has become an essential and powerful tool. It is specially suitable to detect dangerous storms that are difficult to observe and to predict through other instruments. When the ondes of his they are transmitted from the aerials of the radar, during sa trajectory they can enter in touch with objects such like particles of dust or crystals of ice. They enter in touch with an object that goes away from the radar, the waves of his will be reflected to|in the return in a handicapped frequency (that is, of the miner amount of waves of his will be reflected and they will turn during a period of weather given). If the object with what they enter in touch moves around in direction on the radar, the waves of his will reflect itself in an increased frequency.
Radars of SMC. Imatge composts Puig d'Arques, La Panadella i Tivissa-Llaberia, from the datum of the net of weather radars (XRAD), formed by the radars of Vallirana. The compound image is generated from an superimposition of the observations of the four radars until 240 km of radium about each radar. The information corresponding to the area of intersection comes from the radar that sees each point better. The resolution of this image is of 1 km and it updates every 6 minutes.
Treats itself like type images CAPPI that show observations to in the same way altitude (1000 m). The images CAPPI are generated from series of observations carried out with an angle of elevation of the constant aerial about the horizon, PPI known like type images. The hour of the images it|she is expressed in Universal Weather (in timetable of winter the official hour hour is the hour TU+1 and in timetable of summer the official hour is the hour TU+2 hours).

Radars thanks to wetter24. It is a radar with a composition of all Europe, like this that in it paginates it of wetter24 you can find a complete radar.
Radars thanks to AEmeT .Images of reflectivity corresponding to the lowest elevation of the radar exploration (0,5º about the horizontal plan). The scale of color points out intervals of reflectivity in decibels Z. The indicated hours they refer to the peninsula
Radars thanks to Meteo60. On the original page you will be able to see an animation of the last 2 hr
