Abstract EN
Global warming has increased the chance of concurrent extreme climate events (weather or climate events that are rare within their statistical reference distributions in a particular place, such as heat waves, floods, and droughts).
Crops grow best within specific temperature intervals, and excessive heat is detrimental to the physiological processes of crops and eventually affects yield levels.
Analysing historical changes in concurrent extreme high temperatures is critical to preparing for and mitigating the negative effects of climatic change.
The North China Plain (NCP) is the most important wheat production area in China.
In this study, the spatiotemporal variations in temperature and heat wave trends in the NCP were analysed.
Furthermore, we examined the potential of solar-induced chlorophyll fluorescence (SIF) to capture the influence of heat wave impacts on wheat crops in the NCP by comparing satellite remote sensing data of SIF and normalized difference vegetation index (NDVI) and validated ground-based yield data.
The results indicate that temperatures and the number of heat wave days in the study region all show increasing trends, especially daily minimum temperature, which has increased by 0.38°C per decade for the past 30 years.
Spatially, the southern NCP has suffered greater increasing-temperature trends and more heat wave days than the northern region.
Regarding the response of SIF and NDVI to heat waves, SIF can better capture wheat yield decline due to heat waves compared to NDVI; thus, the SIF result indicated more sensitivity to heat waves compared to NDVI.
