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
