三清山云海的气候特征与气象因子的关系

Climatic Characteristics of the Sanqingshan Cloud Deck and its Relationship with Meteorological Factors

因三清山位于玉山境内,用玉山气象站2005-2015年的地面气象要素资料,分析了近11 a三清山云海的气候特征及其与气温、降水、相对湿度、风速的相关关系,并通过逐步回归算法得出了云量与日平均气温、前一日降水、相对湿度的等式关系。结果表明,三清山年平均云海日数为169 d,云海日数的月变化呈现多波动的形势,且1-6月云海日数明显多于7-12月。三清山平均低云量与平均相对湿度、前一日降水量显著正相关,与平均温度、最高气温、最低气温呈负相关关系。

Because Sanqingshan is located in Yushan,using the surface meteorological elements of Yushan Meteorological Station from 2005 to 2015,the climatic characteristics of the Sanqingshan cloud deck and its correlation with temperature,precipitation,relative humidity and wind speed in the past 11 years are analyzed,and the stepwise regression algorithm is adopted.The relationship between cloud amount and daily average temperature,precipitation on the previous day,and relative humidity is obtained.The results show that the average annual number of clouds and seas in Sanqingshan Mountain is 169 days,and the monthly variation of the number of cloud shows a lot of fluctuations,and the number of days in the cloud deck of January-June is significantly more than that of July-December.The average low cloud amount in Sanqingshan Mountain was significantly positively correlated with the average relative humidity and the previous day's precipitation,and negatively correlated with the average temperature,the highest temperature and the lowest temperature.
