中文摘要	沙塵一般由耕作土地上向廣大的區域輸送，使得這些區域PM10與PM2.5的值有相當程度的增加。美國則將沙塵導致能見度下降至5/8浬視為劇烈天氣。而台灣位於中國大陸東側，也正是東亞主槽的位置上，因此，初春時期當極地大陸冷高壓從中國大陸耕地上隨著槽線離開源地向東南移動，使得台灣部分地區亦受影響。沙塵的影響不但使PM10與PM2.5值增加，亦造成當地居民健康方面的疾病。為了對沙塵有更進一步的瞭解，環保署過去也委託執行許多相關計畫。本計畫主要目的在設計與建置沙塵暴資料庫，將沙塵暴事件加以蒐集整理並利用天氣形勢分類。另外，計畫中最後一部分亦嘗試將未來工作重點沙塵暴強度分級作一初步的整理。

摘要	The blowing dust from the normally arable land can be transported downwind to an extensive area. In those areas the observed amount of PM10 and PM2.5 increased to a certain degree. In United States weather observing practice it considered as a severe weather if blowing dust reduces the visibility to below 5/8 statute mile. Taiwan is located in the east coast of mainland China. It is the mean position of the East- Asia major trough. Therefore, during the period of early spring, when a cold high moves out from the arable areas of Mainland China following a propagating trough dust filled air would be affected an extensive area of Taiwan. The falling yellow dust is not only increase the PM10 and PM2.5 but also affects the health of the local residents. In order to make a complete investigation of such condition the EPA supports a number of projects including this one. In this project a data bank of duststorm/sandstorm events is designed and constructed. Data of each case in the recent years are collected and put in the bank. Then, according to those data weather map patterns are classified. In the last part of this work the intensity of the dust event are categorized. Although this work is preliminary it is a very fundamental base of further study.

摘要

The blowing dust from the normally arable land can be transported downwind to an extensive area. In those areas the observed amount of PM10 and PM2.5 increased to a certain degree. In United States weather observing practice it considered as a severe weather if blowing dust reduces the visibility to below 5/8 statute mile. Taiwan is located in the east coast of mainland China. It is the mean position of the East- Asia major trough. Therefore, during the period of early spring, when a cold high moves out from the arable areas of Mainland China following a propagating trough dust filled air would be affected an extensive area of Taiwan. The falling yellow dust is not only increase the PM10 and PM2.5 but also affects the health of the local residents. In order to make a complete investigation of such condition the EPA supports a number of projects including this one. In this project a data bank of duststorm/sandstorm events is designed and constructed. Data of each case in the recent years are collected and put in the bank. Then, according to those data weather map patterns are classified. In the last part of this work the intensity of the dust event are categorized. Although this work is preliminary it is a very fundamental base of further study.
