Via Satellite Interviews Spacebridge
Series often known as the advanced Television Infrared Observing System satellite (The first meteorological satellite was one of many TIROS households). In order to receive information from Meteosat you’ll need to have a hard and fast dish antenna mounted with a transparent facing facet to zero deg. Every half an hour the globe is scanned and the information is split in to smaller blocks and despatched down according to a dissemination schedule.
Snow and lightweight drizzle both produce radar reflectivity with about the same worth. Melting snow and moderate rain even have similar values. Very high reflectivity’s (the greys on the size on the picture above) are always related to hail.
The location of the collared radar echoes indicate the place precipitation is falling and the assorted colours point out the intensity of the precipitation by way of the colour code within the decrease left corner of the image. The instance radar image above shows a number of sturdy thunderstorms transferring through Illinois and Indiana on April 20, 1996. Regions of sunshine and dark blue indicate areas of lighter precipitation while areas of pink and pink indicate strong, to occasionally extreme thunderstorms. Full resolution knowledge, however recorded with an on-board tape recorder for subsequent transmission throughout a station overpass.
This picture reveals the reflectivity area from the attention wall of Hurricane Andrew. The symmetry proven on this picture signifies that Andrew was a really properly developed hurricane. The ring of orange are the high reflectivities associated with the convection found in the eye wall.
Tornadoes are often positioned at the middle of a hook-formed echo on the southwest facet of thunderstorms. The hook is best noticed in the reflectivity subject. This image reveals a reflectivity field containing a number of hook echoes related to thunderstorms that occurred in Tennessee and Kentucky on May 18, 1995. Normally, it’s tough to distinguish precipitation kind on the premise of the radar reflectivity alone.
