| 摘 要： | 通过对长白山地形的分析,研究它与大气环流的关系,总结出受长白山影响所产生的地方性天气系统及其对周围天气的影响。结果表明,长白山小高压是在长白山系和周围海路状况的影响下形成的,分为环绕长白山的地方性低槽系统和长白山高压系统2种情况;长白山小高压又分为弱环流形势下和有明显锋区下2种类型,2种类型影响下所产生的长白山小高压系统与其产生的天气现象的关系密切。由小系统所产生的灾害性天气过程也给社会生产和人们生活带来了一定的影响,研究地方性小系统对准确做好每天的短期天气预报、局地天气预报和防灾减灾有很大的帮助。 |

| Abstract: | Through the analysis of the topography of Changbai Mountain,the relationship with atmospheric circulation was studied,the local weather system and effects on the surrounding weather were summarized.Through the analysis of Changbai Mountain small high pressure,the big circulation situation and the relationship between the local system were revealed,both contact each other and restrict each other.The severe weather process produced by small system have effects on social production and people's life,local small system research will be beneficial for short-term weather forecast,disaster prevention and mitigation. |
| Keywords: | Changbai Mountain Small high pressure Weather system Local areas Influence |
