Under the background of global warming

the high temperature events occur frequently

which has brought great impact to human society. In order to study the change of high temperature events in Jiangxi province

based on the daily maximum temperature data from 91 weather stations in Jiangxi province from 1961 to 2022

the temporal and spatial distribution characteristics

the climate change characteristics and the extremities of the high temperature in 2022 in Jiangxi province were analyzed. The results showed thatthe duration

coverage and comprehensive strength of high temperature had broken through the historical extreme value in 2022. In midsummer（the July and August）

the average temperature

maximum temperature and minimum temperature in Jiangxi all showed an increasing trend

with growth rates of 0.08 ℃/10 years

0.04 ℃/10 years and 0.17 ℃/10 years respectively. This change trend reflected that the frequency of high temperature heat wave events was increasing. At the same time

it would lead to the further reduction of the daily temperature range.The probability of warm nights further increases

leading to the increase of "white+black" composite high temperature events. The demand for power supply would continue to increase. And it also poses a serious threat to human health. Therefore

we must take more effective measures to tackle climate change. Firstly

it is suggested to strengthen the mechanism research and early warning linkage response of the high temperature events. We should firmly establish the understanding that "high temperature events is a disaster". We should strengthen basic research on the characteristics of high temperature weather

climate change and the mechanism of meteorological disasters. Secondly

we should improve the energy emergency security mechanism for high temperature events. Strengthening the energy security connection with surrounding provinces and cities will help to build a stable and safe energy security system. Thirdly

meteorological disaster risks and climate carrying capacity should be fully considered in urban planning

construction and operation. Improve the overall planning of urban buildings

green spaces

roads and other public spaces

open up urban ventilation corridors

increase urban air mobility

and alleviate urban "heat-island effect" and other problems.
