“Have you ever heard a weather forecaster predict "random" afternoon "pop-up" thunderstorms on a summer day? In hot, humid summer air masses, it may seem that thunderstorms erupt rather randomly. But, thunderstorms never really erupt randomly, even if it appears that way. Think about it: "Random" thunderstorm development would mean that they develop on a whim, for no reason at all. As you've learned, thunderstorms tend to form when air parcels can become positively buoyant after being given a nudge upward (perhaps from low-level convergence along a cold front or sea-breeze front)….“
“ …These disorganized, individual thunderstorm cells that are sometimes referred to as "random pop-up" thunderstorms are single-cell thunderstorms. The reason they often appear random is because we don't have the capability of predicting exactly where and when local conditions are just right for storm initiation.”
我諗呢個世界除咗大交合之外，冇乜邊個氣象機構咁強調雷雨發展係隨機
大交合唔可以預早知道大約幾時香港會有大雨，好大程度只係因為佢唔似外國咁有資源技術去估計至少未來幾個鐘天氣變化。佢話係隨機所以冇得預測只係掩飾自己嘅不足。
下次大交合再講大雨係隨機，記得笑Seven佢
我覺得係班AO同渠務/路政處夾硬叫天文台搵藉口堵塞10號波個預後問題
個濕勁總動員流於表面兼無用，唔想理啦
但渠落曬波後從來似乎冇全面檢查到低窪去水系統先係今次浸得咁癲嘅主要緣故
要話預測天文台實有氣象圖兼mon到殘留雨帶強度去向提示其他公務部門要處理暴雨渠務，成班科學主任同各路政/渠務部門每次有強雨帶都去祈禱要個雨團儘快減弱唔好奶野咩，政府做成幾十年嘅去水渠廣告你估流咩
到落啦，係就係好向左走向右走大，但第一次落雨由黃大仙同北區大浸（前者塞渠後者深圳突擊泄洪），到第二次觀塘將軍澳柴灣水浸（又係塞渠）
我先唔覺係咩乜巧合，天文台作爲PR相對好嘅俾其他濕勁部門拉去做遮醜布就真
