Comparison of the Synoptic Environments Conducive to Eastward versus Southeastward Transport of Asian Dust Events

Table 1

The date of selected eastward and southeastward dust events in Taiwan and Japan respectively, their peak hour at Wanli, Taiwan, and Matsue, Japan, obtained from surface or lidar measurements, their maximum PM₁₀ concentration at northern (Wanli) and southern tip (Hengchun) of Taiwan, and number of Japanese stations that observed the dust events.
