| 摘 要： | 本文应用美国国家气象局提供的1958—1997年全球大气精确的轨道参数和涠洲岛地区风速和风向等数据资料，模拟了火山喷发时空降碎屑的分布情况。结果表明，涠洲岛地区火山喷发形成的空降碎屑分布与喷发时的风速与风向有关，NNW方向的风可使空降碎屑影响到海南省北部地区，SSW方向风可使空降碎屑影响广西东南部和广东西南部的广大地区，1月和7月份喷发时主要影响涠洲岛及周边海域。 |

| Abstract: | Applying the global atmospheric accurate obital parameter(1958-1997),wind speed,wind direction and other data of the Weizhou island area,the airborne ash distribution of the volcano eruption was simulated.The result showed that the airborne ash distribution of the Weizhou island volcano eruption related to the wind speed and wind direction,airborne ash can effect the Northen area of Hainan province as NNW wind,south-east area of Guangxi and south-west area of Guangdong as SSW wind,eruption on the Junuary and July affected Weizhou island and its sea area. |
| Keywords: | Weizhou island volcano activity numerical simulation airbone ash |
