Notes:

  • The center of the image points a weather radar near Zhuhai Jinwan Airport. The radar was built by Macao Meteorological and Geophysical Bureau and Zhuhai Meteorological Bureau. It is situated about 26 km southwest of Macao.
  • The image shows the rainfall rate at a height of 3 km above mean sea level. The time stamp on the radar images represents the Macao local time (UTC+8:00) when the radar completed its scans. The colour scale on the right indicates the magnitude of the rainfall rate.
  • The radar scanning range is about 240 km; images updates once every 6 minutes.
  • Weather radars send pulse of electromagnetic radiation, and estimate the rainfall with the reflectivity from hydrometeor.
  • An empirical formula is used to convert the reflectivity into rainfall rate. Thus, the rainfall rate showed in the image is only an estimate. Additionally, the rainfall rate refers to the 3-km mean sea level, so the rainfall reaching ground could be different. For surface rainfall distribution over Macau, please visit Actual Weather Report.
