摘要
利用眉山地区204个气象站点30年的月均气温、月均相对湿度、月均日照和风速等气候要素,计算温湿指数和风效指数,并对其空间分布规律及各月份气候的舒适性进行了分析。结果表明:眉山市温度差异较为一致,除彭山地区温度较其余区县高3℃~5℃,眉山地区的气候舒适度的总体分布趋势是随经度和海拔变化,由高到低、自西到东递增。气候舒适期整体呈现西高东低。气候舒适度计算结果表明,最长舒适度为7个月,最短为5个月。
Based on the climate elements such as monthly average temperature, monthly average relative humidity, monthly average sunshine and wind speed of 204 meteorological stations in the Meishan area for 30 years, the temperature humidity index and wind efficiency index are calculated, and their spatial distribution law and the comfort of climate in each month are analyzed. The results show that the temperature difference in Meishan city is relatively consistent, except that the temperature in the Pengshan area is 3˚C~5˚C higher than that in other districts and counties, the overall distribution trend of the wind efficiency index decreases from north to south and from low to high with the change of dimension and altitude. The overall climate comfort period is high in the West and low in the East. The calculation results of climate comfort show that the longest comfort is 7 months and the shortest is 5 months.
