From the top going clockwise they are:
- 洗濯指数: Laundry index, how thick of clothing will dry
- 星空指数: Starry sky index, I think how clear the sky is
- 服装指数: Clothing index, how thick of clothing is recommended
- 傘指数: Umbrella index
- 紫外線指数: Ultraviolet index
Interesting how the weather report tells you whether to wear a sweater, bring an umbrella, or sun block.
