(舊文) 下星期48小時內氣溫驟降14度

天文台預料現時的和暖海洋氣流下周初將會被一道冷鋒取代
本港星期日預測最高氣溫28度, 隨後會明顯轉涼
星期一最低氣溫會跌至18度, 星期二會再跌多4度只得14度
夏天來臨前大家仲有機會著多次大褸

天文台七天天氣預報

如此急轉的天氣下容易感冒, 請大家注意身體

o 哂咀
仲以為四月開始應該唔會再凍
仲諗住收埋 D 棉胎和厚褸添

愚人節過後估計會有好多人中招
著多件衫啦

不過近呢兩年四五月0既天氣好似有
少少反常咁。因為我記得0係五月中
試過兩次可以得返 20 - 21 度。

今年天氣真是多反常,
都唔知道幾多人被天氣玩殘呢?

今年我都傷風左兩次..
呢排天氣一日曬一日寒, 真係令人無所適從.

More abnormal example:
2/4/07: There is a partly-sunny to mostly-sunny day (sunshine hr: 6.6 hr)
However, HKO guesses the situation scientifically not very good.  The weather report stated: sunny to rainny to cloudy to sunny again within 7 days. (*10) (*20)
2/8/07 - 2/9/07:  Stop the moon at night!
The weather of both day times is sunny and warm, but there is shower available at night.  Hence, no such moonshine is available on 2/8 night.
2/23: There was a partly sunny day that should not be expected. (*10) (Sunshine hour on 2/23: 7.7 hr vs. no sunshine is valid on 2/22 and 2/24 )
February 07: The highest average and the lowest mean temperatures recorded by Hong Kong Observatory.
3/5: Before the cold front, some sunshine is avaliable. (*5)
3/7: See also board A20: the cold front causes the rain and sudden cold weather (10.6 degree C) (Why nobody discussed this case with me in board A20?)
3/19: 1.There is very little sunshine in the afternoon.  Shortly-sunny board appeared on the board of HKO real time weather. (*10)
2. Normal case: this is the first thunderstorm in 2007.
3/27: The partly-sunny situation appeared that HKO is not expected, and the highest temperature of the month is underway.
3/29: The shower stops!  It is normal change, but the night time shower makes the situation harder to be expected correctly.
3/30, 3/31, and 4/1: The temperature can go up to 28 degree C because of the partly sunny situation.
4/1: There is yellow fire (!) and mostly-sunny day; shower is also avalible in selected districts; enjoy the April Fool!  Do not forget the cold front and thuderstorm tommorrow... (Not the joke of the yellow fire, but I beleive that this may be the last yellow fire on 06/07 Winter and Spring.)
4/2: Stop the sunshine, cold front starts and do not forget the lati-thunderstorm!

俗語有話：
「未食五月糉，寒衣咪入籠」，
依家先係農曆二月，
仲有排捱呀……

話晒依家都仲叫做「春天」，
乍暖還寒乃正常現象，
不過兩日之內跌咁多度，
又過份o左Ｄ……

記得十二月十幾二十號左右，
又係呢隻「跳樓式急凍」，
兩日之內，
由最高 26 、 27 度，
跌到得返 12 、 13 度……

不認為這年的天氣特別反常

單比較降溫幅度
看回2005年亦已經有一個相似例子
當時溫度由4月12日最高的攝氏24.6度
降到4月13日攝氏14.6度

如果說自1884年以來
天文台4月錄得的最低溫度
是在1969年4月5日錄得
低至攝氏9.9度
而在之前一日的最高溫度
同樣高達攝氏24.1度

當然
只比較降溫幅度未必能驗證是否「今年天氣真是多反常」
但從一些例子看來
24小時內急降10度也非罕見的事情
(甚至小弟覺得...
熱島效應令降溫幅度較以前小)
