摘　　要：为了进一步探索潍坊市的气候演变规律,合理利用气候资源,本文利用现代气候学统计诊断方法,对潍坊市2022年的气温、降水、日照等基本气象要素进行统计分析。结果表明:2022年潍坊市年平均气温14.0˚C,较常年偏高0.6˚C;2022年潍坊市极端最低、最高气温分别为−12.0˚C和39.2˚C;11月、12月的平均气温指数综合评价分别为异常偏高和显著偏低。2022年潍坊市年平均降水量1033.6 mm,较常年平均降水量偏多62%;2022年潍坊市降水时空分布不均,中部县(市、区)年降水量明显多于北部和南部,冬、春季降水严重偏少,导致部分地区出现不同程度的干旱。2022年潍坊市年平均日照时数2367.2 h,较常年偏少4.8 h。北部县(市、区)的年日照时数明显多于南部。年内主要气象灾害为干旱、干热风、冰雹、暴雨和台风。In order to further explore the law of climate evolution in Weifang and make rational use of climate resources, in this paper, the basic meteorological elements of Weifang in 2022, such as temperature, precipitation and sunshine, are analyzed by using modern climatological statistical diagnosis methods. The results show that the annual average temperature of Weifang in 2022 is 14.0˚C, 0.6˚C higher than that of the normal year;The extreme minimum and maximum temperatures in Wei-fang in 2022 are −12.0˚C and 39.2˚C respectively;The comprehensive evaluation of the average temperature index in November and December is abnormally high and significantly low, respectively. The average annual precipitation of Weifang in 2022 is 1033.6 mm, 62% higher than the average annual precipitation;In 2022, the precipitation in Weifang City is unevenly distributed in time and space. The annual precipitation in the central counties (cities, districts) is significantly more than that in the north and south. The precipitation in winter and spring is seriously less, leading to different degrees of drought in some areas. In 2022, the average annual sunshine hours in Weifang City will be 2367.2 h, which is 4.8 h less than that in normal years. The annual sunshine hours in the northern counties (cities and districts) are significantly more than those in the south. The main meteorological disasters in the year were drought, dry and hot wind, hail, rainstorm and typhoon.
