Flying Sand a Seasonal Headache for Hualien|東北季風颳起揚塵 花蓮河床漫天風沙公視 (2019-09-19 00:00)
Due to the effects of the northeast monsoon and dry weather, many of Hualien's rivers have run dry in recent days. This has resulted in flying sand over an area of several kilometers that is affecting both road visibility and air quality. Hualien residents and tourist have been advised to put on surgical masks before heading outside.
There is sand flying all over the place around the Hualien River estuary. Visibility is very poor on Hualien Bridge, and scooter drivers are having trouble keeping their eyes open.
(Have you seen anything like this before?) No, this is the first time we've seen this. Did you get sand in your eyes? Yes. (It's uncomfortable?) Yes.
The northeast monsoon is carrying sand from riverbeds inland, affecting several kilometers in area. The situation is especially severe around the Liwu River estuary. Local residents say this always happens when rivers run dry during monsoon season, and all they can do is keep their doors and windows shut.
When you combine Category 7 winds with dry weather, rivers run dry. The wind picks up the sand from the riverbeds. The particles are significantly larger than PM2.5.
The Hualien Weather Station says flying sand isn't the same as sandstorms but both pose a risk to people with respiratory conditions. Therefore, Hualien residents and tourists should put on surgical masks before heading outside. The station also says there is currently no way to solve or ameliorate this problem due to geological and geographical factors.
機車騎士 林先生表示：「(平常會有看到這樣風吹沙的狀況嗎？) 不會。(第一次看到， 眼睛都進沙子了，是不是？) 對。(不舒服喔？) 對。」
花蓮氣象站 主任 譚廉表示：「最大陣風快要到七級，然後相對濕度也比較低，所以整個河床大概是比較乾燥，然後如果風比較大，風向對的時候，那比較細的粉塵就會被吹起來，所以基本上它會比PM2.5大很多。」
