    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.

Yesterday's (01 Jun 2018) average ambient gamma radiation
dose rate taken outdoors in Hong Kong ranged from 0.08 to
0.15 microsievert per hour.  These are within the normal
range of fluctuation of the background radiation level in
Hong Kong (see Note). The average dose rates measured at the
radiation monitoring stations over various parts of the
territory were as follows :

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.
