The thunderstorm will be coming; if one likes thunderstorm, one will not be too disappointed. :PReturn to the question, HKO replies the information not so accuaretely because the weather changes instantaneously.For example, HKO stated that there is shower, but not sunshine, on 5/10 - 5/13/07, but what is happened finally?There is sunshine on the 4 days, but no such shower happens.What is wrong?
There was low air trough (lat, #232) inNorthern South China Sea, and there was high air ridge (har, #231-233) in Shouteast China.Theorectically, the weather in Hong Kong should be lati-sunshine-tude-thunderstorm.However, no shower was possible because the lat is not stronger than the har.Finally, the lat destoryed first.This is the idea to explain why there was no shower in Hong Kong on 5/10 - 5/13.In fact, there was the sunny period from 5/6 to 5/18 (before the evening T-shower).
I beleive that sunshine and thunderstorm needs to be balanced in the same year; because there is too much sunshine, the thunderstorm happens perfectly in time. :) (Why?)
The story (Part 1, on 5/10, 5/11) :time:
The group of cloud-thunderstorm: Where is the shower? :o
The group of sunshine: The shower (may be selected district) does not happen in HKO, so this states that the shower "does not
happen".
The gods: Sorry, this is our fault... :L
hp7629: The weather changes instantaneously causes this ending, and nobody even gods can change this.:victory:
(Part 2, 5/18 afterward)
The group of cloud-thunderstorm:Thanks for the lati-thunderstorm, but where is it?
The gods: Oh, the thunderstorm is coming, see you later... :)
The group of sunshine: How about sunshine?
The gods: According to the scientific report, this seems not be possible because no shortly sunshine is allowed to mix with the
shower (for example, on 5/5/07 :time: ).However, because the weather changes instantaneously, every situation
may be possible. (The solution of #2)
hp7629: Therefore, because there is not another high air ridge that builds up, no next sunny period in Hong Kong next 7 - 12
days.
(Part 3, 5/22 - 5/31)
The group of cloud-thunderstorm: We need any rain (and thunderstorm), but not sunshine. :)
The group of sunshine: We need lat, but not har within this May. :victory:
The group of cloud-thunderstorm: (say to the group of sunshine) :funk: (*20)
The group of sunshine: In fact, we have not discovered that the next har will appear within this May.
Solution to the board #2:The shortly sunny does not appear because the weather in Hong Kong on 5/19 is thunderstorm.In
this case, HKO does not state the weather that includes the shortly sunny.
In fact, if the weather is a rainny serious, then no shortly sunny is included.
Exception: If the weather is cloudy, and somewhat sunshine is possible, then the shortly sunny is valid.For example, the
weather is cloudy and shower (very little?!) in the morning on 5/10, then HKO represents cloudy because the
shower is very weak.If the shower were stronger, then HKO would represent as light rain (no-sunshine-shower).
After that, because the sun shines, then HKO uses the shortly sunshine to represent the weather in the afternoon
on 5/10.Similarly as on 5/11 case, but there was more sunshine on 5/11 than that on 5/10.
Next, let us introduce a special case: if some day is holiday, then sunshine may be possible. :time: :o
In some cases, this statement can be true while some cannot be true.Why?
Because the situation is still unchange: according to HKO, there is shower next 7 - 12 days.
The sun does not shine anymore from 5/25 to 5/26, may be from 5/27 and 5/28???Good luck!
The soutwest monsoon is defined as lat #234A in this case.No har #235 has appeared yet.Hence, the sunshine and shower can appear together, but har is irrelavent in this case. :victory:

[ 本帖最後由 hp7629 於 2007-5-22 04:00 編輯 ] 近期也發覺預測有點問題，因為很多時實際最高氣溫比預測最高氣溫高三至四度。 原帖由 petcity 於 2007-5-19 10:18 發表 http://www.hkitalk.net/HKiTalk2/images/common/back.gif
究竟搞乜？唔通玉兔惹的禍？
應該唔關個玉兔事，
玉兔距離唔好講香港，連華南沿岸都有返咁上下遠距離咁遠:L
天文台剛剛於1250發出雷暴警告

Take more example:There was lati-sunny on 4/18 :loveliness: after the the cold front-lati-thunderstorm at night on 4/17/07.What is the temperature on 4/18?
The highest: 28.3 degree C; :o:D
The lowest: 17.4 degree C; :L
The difference: 10.9 degree C! :L(*10)
Is it posible in Hong Kong?I do not think so, because in normal case, the temperature difference in lati-sunny days is: 5 - 6 degree C in summer, and 4 - 5 degree C in any other 3 seasons.Outside the range is abnormal: the difference < 4 means the weather in particular day is not equal to sunny; the difference > 7 means the weather changes instantaneously and very abnormal.
:P
