摘要:

利用河南省111个国家气象观测站近30年(1991—2020年)的地面气象资料,包含逐日最高气温、平均相对湿度、降水量、风速、云覆盖率等气象要素,分析河南省度假气候指数的时空变化特征。结果显示:河南度假气候指数1—12月份达到“适宜”及以上等级,月变化呈现双峰型,在4—5月和9—10月最高,达到“特别适宜”等级;度假气候指数在季节变化上,春秋两季最高、夏季次之、冬季最低;空间分布上年内呈现“北高南低”的特点,季节分布上呈现明显的区域特点和一定的维度特点。

关键词: 度假气候指数, 时间变化, 空间分布, 河南省

Abstract:

In this study, the spatial and temporal variation characteristics of holiday climate in Henan province are analyzed using the ground meteorological data (including daily maximum temperature, average relative humidity, precipitation, wind speed, and cloud-coverage rate) from 111 national meteorological observatories in Henan province for the past 30 years (1991—2020). The results show that the holiday climate index(HCI) of Henan reached a “suitable” or a more than “suitable” level from January to December, and the monthly variations present bimodal characteristics. In April to May and September to October, reaching the highest level “particularly suitable”. The Henan HCI indicates that the seasonal variations are the highest in spring and autumn, followed by summer, and the lowest in winter, the spatial distribution presents the “high in north and low in south” characteristics, and the seasonal distribution presents certain dimensional characteristics and obvious regional characteristics.

Key words: holiday climate index, variation of time, spatial distribution, Henan Province
