Abstract:The Yunnan Guizhou quasi stationary front occurred in Southwest Guizhou in recent five years (2015-2019) was used for statistical analysis,This paper analyzes the regularity of quasi stationary front appearing in Southwest Guizhou under different types of Yunnan Guizhou quasi stationary front and the distribution characteristics of elements nearby,Combined with the actual temperature data of 8 stations in Southwest Guizhou and ec-2t forecast,Using the deviation correction method, the correction equation is established. The results show that: In the five years, the number of stationary front days is the most in the spring of 2019, The number of days of stationary front was the least in the spring of 2016, Most of them appeared in March: Qianxinan prefecture has the most days in the cold air mass behind the front (type I), Among the warm air masses in front of the front (type II), The days of weak static front are the most,The days of strong static front are the least The days of strong static front in March were the most; Near the quasi stationary front of Yunnan Guizhou, The distribution of meteorological elements presents different characteristics, That is, the distribution characteristics of the highest and lowest temperature space are basically "high in the southeast and low in the north", The spatial distribution of rainy days is "high in the West and low in the Southeast"; After the correction equation is established, in southwestern Guizhou has been improved in each month.
