I refer to the letter from J. Lee headlined, 'Discrepancy' (South China Morning Post, December 31). I also have some questions for the Hong Kong Observatory.
I agree with J. Lee that sometimes the temperature seems lower than that reported by the observatory.
Also, the air pollution index reported is usually low, ranging from fair to good, when in actual fact Hong Kongers are daily breathing in fumes and choking in the pollutant-filled air.
But what is perhaps the final straw for me is that a few days ago, as on numerous occasions before, the observatory reported the relative humidity to be about 75 per cent, yet the yellow fire-danger warning was in place.
If the relative humidity could be as high as 75 per cent how was the air considered to be so dry that a fire-danger warning was thought necessary? Does it have something to do with absolute humidity, or does it depend on the kind of winds that are blowing? It certainly seems to be the case sometimes, that when the relative humidity is in the range of 70 per cent to 80 per cent, it still feels dry.
I hope the observatory will answer my questions.
