摘要
通过统计分析的方法,研究宁波西南山区地形对强对流天气的影响。先通过30年统计资料分析出宁波西南各类降水指标远远高出其他地区的整体趋势;再对台风系统和非台风系统分别进行统计分析,发现两种情况下宁波西南各类降水指标也都明显高于其他地区;接着从月尺度、日尺度、时尺度继续进行统计分析,发现宁波西南在月均降水量、连续降水过程总量、极端降雨量、极端降雨频次等方面也都明显高于其他地区;最终得出,正是宁波西南的这种山区地形造成了该地区强对流天气的多发和易发。
In this paper,the statistical analysis method is used to study the influence of the terrain in southwestern Ningbo on the convective weather.Firstly,through statistical data for 30 years,the overall trend of precipitation indicators in southwestern Ningbo is far higher than that of other regions.The typhoon system and the non-typhoon system are then separately analyzed.It is found that precipitation indicators of various types in southwest Ningbo are also Both are significantly higher than those in other regions;then statistical analysis on the monthly,daily,and time scales and found that southwestern Ningbo is also significantly higher in terms of monthly average precipitation,process total precipitation,extreme rainfall,and extreme rainfall frequency.Finally,it is concluded that this mountainous terrain in southwest Ningbo has caused frequently and easily Severe convective weather in this area.
