The Theme of the Calendar

 

The calendar displays beautiful photos of weather and optical phenomena mostly contributed by photography enthusiasts through the Community Weather Observing Scheme. Members of the public can appreciate the wonders of nature through these photos, which include scenes of double rainbows, asperitas and upslope fog. The Hong Kong Observatory (HKO) hopes that the photos will encourage the general public to protect the environment, be aware of climate change and its impact, and embrace a greener lifestyle.
