根據中央氣象局統計1991~2020年雲量每月平均統計,在鞍部觀測站(陽明山國家公園內)的雲量最多平均7.8,最少雲量在玉山觀測站平均5.0
Yangmingshan National Park has a maximum average of 7.8 cloud cover,the least cloud cover averages 5.0 at Yushan Observatory
最多雲量出現前的雲層變化-火燒雲
Changes in cloud cover before maximum cloud cover-fire cloud
最少雲量出現前的雲層變化-雲少無變化
Changes in cloud cover before the occurrence of minimum cloud cover-no change
低氣壓伴隨的外圍環流雲帶,當這些較長波長的紅光、黃光通過雲層底部,就會形成朵朵火紅的火燒雲了!且低氣壓會將雲給吸走造成無雲狀況
When these longer wavelengths of red and yellow light pass through the bottom of the cloud layer, a fiery red fire cloud will be formed!And the low pressure will suck the clouds away, resulting in a cloudless condition
The clouds around the eye of the typhoon are solid and continue to move to the northwest
在109年8月2日為雲量最多當天,根據影像顯示此為颱風位於臺灣東方海面,明顯的環流雲帶則伴隨局部對流,外圍環流已經觸及臺灣東部、東北部地區;並持續往西北方方向前進。
