Abstract

Abstract: Based on the daily maximum temperature, average temperature, minimum temperature, precipitation, relative humidity, sunshine, wind speed and other meteorological data in Tianmen city from 1955 to 2019, the variation characteristics of climate and human comfort in Tianmen city were analyzed. The results showed that the maximum temperature, average temperature and minimum temperature all showed a warming trend in Tianmen city, and the warming range was minimum temperature>average temperature>maximum temperature. The interdecadal variation characteristics of temperature tended to be consistent. The temperature was low from 1950s to 1990s and high since 1990s, but the temperature change tended to slow down after 2010. More than 80% of the years in Tianmen city, the number of suitable temperature days, the suitable grade of precipitation, the uniformity of precipitation season, the suitable grade of relative humidity and sunshine were excellent level. In recent 65 years, the temperature humidity index, wind efficiency index and comfort index showed an upward trend, and had been at the comfort level since the 1990s, reflected the climate characteristics of livable, business and tourism in Tianmen city.

Key words: climate characteristics, temperature humidity index, wind efficiency index, comfort index, Tianmen city
