Dbz in weather radar
WebThe radar image above from 2255Z on June 1, 2012 shows a line of strong thunderstorms (called a "squall line") just to the west of State College, Pennsylvania (UNV on the map). Although the storm moved through the region very quickly, rainfall rates at the Penn State Weather Center exceeded 0.6 inches in a 10 minute period. WebDBz means “Decibels of reflectivity”, and denotes rain (or other precipitation) intensity as measured by a radar. Although a decibel usually measures sound intensity, it can be used for the intensity of any signal, in this case the radar signal reflected back to the radar after hitting a raindrop (or something else).

WebOct 13, 2024 · One of the first coded pieces of data you might notice on a weather map is a 4-digit number followed by the letters "Z" or "UTC." Usually found at the map's top or bottom corner, this string of numbers and letters is a timestamp. It tells you when the weather map was created and also the time when the weather data in the map is valid. WebFeb 10, 2024 · 2.1.2 Airborne weather radar scan mode. The airborne weather radar proposed in this paper begins scanning from the lowest elevation − 15°. The scanning area is a fan-shaped area with azimuth ranges from − 60 to 60° centering on aircraft heading and a radius of 60 km (Fig. 2a). The radar raises its antenna angle by 1° and scans the next …
WebApr 21, 2024 · The radar data used in the study were obtained by an X-band Doppler bipolar weather radar (Figure 1 and Figure 2). The mode of the radar scanning is the plain position indicator (PPI), with a fixed angle of 0.5 degrees and a maximum threshold of 55 dBZ. The scanning period was 3 min, and the spatial resolution of the data is 150 m.
