Effect of Long-range Transport of Air Mass on the Ionic Components in Radiation Fog in Northern Japan

Chemical Characteristics of Fog Water at Mt. Tateyama, Near the Coast of the Japan Sea in Central Japan

“…Chemical measurements of fog water at lower mountain sites near industrial regions were also performed in Japan (Murano 1993;Hosono et al 1994;Igawa et al 1998;Watanabe et al 2001b;Aikawa et al , 2005Aikawa et al , 2007Tago et al 2006). The fog water chemistry was also investigated in northern Japan (Ogawa et al 2004). Ogawa et al (2004) reported the effect of the longrange transport of the air mass on the ionic components in radiation fog.…”

“…The fog water chemistry was also investigated in northern Japan (Ogawa et al 2004). Ogawa et al (2004) reported the effect of the longrange transport of the air mass on the ionic components in radiation fog. Except for anthropogenic pollution, sea-salt and dust particles sometimes highly affect the chemistry of fog water at high elevations in Japan (Watanabe et al 1999).…”

Can Volcanic Dust Suspended From Surface Soil and Deserts of Iceland Be Transferred to Central Balkan Similarly to African Dust (Sahara)?

“…The selection of 500 m as the lowest level resulted from the orography around the station. To elucidate the effect of long-range transport, trajectories are analyzed at low and mid tropospheric altitudes, up to 5000 m (e.g., Ogawa et al, 2004;Sangeetha et al, 2018). The trajectories and composite maps are presented for 700 mb level as the most representative HYSPLIT backward trajectory level based on previous analyses of long-range dust transport episodes for Central European and Mediterranean case studies (Hamonou et al, 1999;Varga et al, 2013Varga et al, , 2014.…”

Increase of Pollutants in Radiation Fog by Fumigation at Takanosu Basin in Northern Japan

“…For the pollution mechanism of radiation fog, the influences of long-range transportation remain insufficiently understood. Results of our previous study demonstrated that the radiation fog in Takanosu Basin includes pollutants transported from the Chinese mainland in addition to pollutants near the basin [5].…”

“…The most important types are radiative, advective, frontal, and upslope fogs [1]. In these fogs, radiation fog is known to be highly polluted and to incorporate many pollutants during stagnation [2][3][4][5]. The highly polluted fog affects buildings and vegetation in the basin [6].…”
