近日香港的天氣

踏入７月香港的天氣因受到華南沿岸的副熱帶高壓影響之下持續１０多日都係天晴天氣酷熱，暫時
踏入夏天未曾掛過任何颱風信號，即時最近吹向海南島個熱帶低氣壓香港都唔需要發出任何的颱風
信號，係今日本港受到這個熱帶低氣壓的外圍環流影響香港今日間中多雲有狂風雷雨，但各位再睇
遠少少現在有個強烈熱帶風暴帕布正以時速約３０公里的速度吹緊向台灣以東海域，之前睇天文台
帕布的預測路徑帕布略過台灣後會在福建及浙江一帶登陸，但天文台在８月６日晚上８時更新左帕
布的最新路徑圖：

在略過台灣後帕布轉向較西的方向移動有進入南海的可能性，但因之前已登陸台灣威力可能會減一
半，總括來說天文台能否掛起今年首個一號戒備信號要睇帕布未來動向。

歡迎各位板友討論及跟進

There are more stories that about the lati-sunny periods on July, and see in the another topic.   

Stop the sunny days until mid-August, and I do not have so many comments because there are too less ( ) t-storms that happen in Hong Kong.
We expect no sunny period that is possible until mid-August.  Also, if HKO states some days are shortly sunny, but not partly sunny or better, (no matter with T-shower or not), then the situation is not stable, and the sun may or may not return that depends on the real weather situation.

Break records in 07/07:
1. The least rainfall record breaks because there is only 76.9mm rainfall that HKO records
    (1/4 of the normal) versus there is 101.8 mm rainfall that records in July 2003.    
2. The very hot weather warning has been occuring until 8/5 when the first city lati-
    storm in August.  (More than 131 hrs! (*100))   
    Latest news: The very hot wearning occured from 07/24 (at 1420) to 08/05 (at 1230), it has been valid up to 358 hours!

Definiton of appeance of shortly sunny:
If HKO states there will be shortly sunny in some days, then in general cases, one and only one of these is true:

1. there will be (at least) partly sunny on the particular day ( the best case).
2. stop sunshine on the particular day ( the worse case).
3. the sun shines 0.0 < t <= 4.0 (where t has the unit of hour)

In case 3 listed above, HKO usually no longer states the shortly sunny in the middle estimation parts in weather forcast.

Toward to the future (next 7 days):

No partly sunny is valid at the moment because of the typhoons (Tropical Low Air Pressure, TLAP).

Will there be next sunny period after 8/12?
The answer is no (according to HKO) because there is very little or even lack of condition to make the next partly sunny reappear.  Therefore, we expect there will be thunderstorms, but not next sunny period.

Can this be changed?  Yes, it can.  However, what is the condition to support the next partly sunny?

Conclusion:
No such sunny period may be possible after the typhoon because it cannot be stated nowadays.
