Significant Weather Information (SIGMET)

The Airport Meteorological Office is responsible for monitoring hazardous weather and phenomena in the atmosphere that may affect the safety of aircraft operations within a designated airspace over the northern part of the South China Sea. Weather forecasters at the Airport Meteorological Office issues SIGMET information when hazardous weather and phenomena in the atmosphere such as thunderstorms, tropical cyclones, turbulence, icing occur or are expected to occur in the airspace.

Note
  1. From readings taken at various locations in Hong Kong in the past, the hourly mean ambient gamma radiation dose rate may vary between 0.06 and 0.3 microsievert per hour. (1 microsievert = 0.000001 sievert = 0.001 millisievert)
  2. Temporal variations are generally caused by changes in meteorological conditions such as rainfall, wind and barometric pressure.
  3. Spatial variations are generally caused by differences in the radioactive content of local rock and soil.
  4. The data displayed is provisional. Only limited data validation has been carried out.
