中文摘要 | 雲幕高,或稱雲冪高,為雲量超過天空一半之最低雲底高度,為航空氣象中之一項參數。本研究探討由歷史性雲量、雲高等觀測資料,萃取雲幕高,以多年觀測紀錄,由長時期統計值分析航空測量飛航雲因風險機率,以為空載光達評估雲因飛航風險之應用。本研究所稱雲因飛航風險,乃以天氣是否適合航空測量蒐集數據為標的。本文先描述雲屬、雲量、雲高等觀測資料之內涵,以及雲幕高之定義與產出方式,並以澎湖馬公機場十年數據作為探討之實例。本研究顯示飛航雲因風險機率確實難於預估,但是長時期統計值亦確實可提供一分析基礎。 |
英文摘要 | Cloud Ceiling is a parameter describing the cloud used in meteorology. This parameter is related to the amount of the cloud and the cloud height at a specific location. From the cloud observations, the cloud ceiling can be derived. This study investigates the probability of cloud caused risk to aerial mapping, based on the historic record of the cloud observations. Because the cloud status could vary drastically from day to day, month to month, and year to year, it is very difficult, if not impossible, to predicate the cloud conditions. This study utilizes more than 10 years cloud observation for the statistical analysis. The observation from Magong airport located in Penghu is analyzed as a sample. It is demonstrated that the monthly statistics does provide information to the cloud caused risk assessment. However, the cloud ceilings are still difficult to predict, as observed from the yearly changes of monthly probability. |
