Abstract Understanding the spatiotemporal characteristics of heat wave (HW) is vital for both natural systems and human populations. Given Loess Plateau's sensitivity to extreme events due its fragile ecological environment, it imperative study variability HW. This research utilized instrumental measurements, climate model data, atmospheric circulation metrics comprehensively analyze past future HW variations their drivers in Plateau. From 1961 2019, daytime wave(DHW) nighttime wave(NHW) were as follows: duration (9.28/9.72 days), frequency (1.34/1.4 times, mean intensity (6.24/4.69°C), maximum (7.83/6.05°C), cumulative (44.45/32.63°Cd). All displayed an increasing trend. Geographically, northern Plateau exhibited highest heat, whereas southern region experienced longer wave. The solar flux index, western Pacific subtropical high area index identified primary factors influencing By end 21st century, are projected rise significantly. NHW, particular, will see extended durations greater compared DHW.

Natural disaster events caused by extreme precipitation have far-reaching and widespread impacts on society, the economy, ecosystems. However, understanding long-term trends of indices their spatiotemporal correlations with remains limited. This is especially true given diverse factors influencing relationship in China, which makes spatial linkage highly complex. study aims to detect recent China link them related natural events, as well evolution land use cover Gross Domestic Product (GDP). Daily data from 1274 rain gauge stations spanning period 1961 2021 were used analyze distribution characteristics index climate China. The results revealed a significant increasing trend intensity eastern but decreasing amount, frequency, duration southwest accompanied increase consecutive dry days. records indicated at an annual rate 1.3 times frequency flood, storm, drought, landslide occurrences nationwide, substantial regional dependence types. Furthermore, GDP levels showed close association induced precipitation. Although number deaths precipitation-related disasters (by 51 people per year), economic losses are annually USD 530,991, particularly due floods storms. holds potential inform decision-making processes, facilitate implementation mitigation adaptation measures, contribute reducing across regions worldwide.

Abstract High air temperatures and low atmospheric humidity can result in severe disasters such as flash droughts regions characterized by high (monsoon regions). However, it remains unclear whether responses of hot extremes to warming temperature are amplified on dry days well the response days. Here, taking eastern monsoon China (EMC) a typical region, we find faster increase drier summer days, decrease hotter indicating “hotter get drier” “drier hotter” (i.e., coupling extremes), especially southern EMC. The EMC is also hotspot where hot‐dry has become significantly stronger during past six decades. associated with anomalies large‐scale circulations, reduced total cloud cover, abnormal anticyclones upper atmosphere, intense descending motion, strong moisture divergence over this region. Land‐atmosphere feedback enhance increasing land surface dryness (seen evaporation fraction). decreasing fraction drying soil moisture, controlled decreases pre‐summer 1‐m summer‐mean precipitation. Given projected predicted future, very likely that will be witnessed regions, which should mitigated against adopting adaptive measures.

Abstract The capture of CO2 has become a global research focus. Rock weathering in the natural environment makes significant contributions to stable carbon at both long and short time scales. However, traditional methods estimating potential are still uncertain due solely instantaneous rates, dependence measured data, difficulty predicting future sink potential. Here, estimated rock using conventional PROFILE model were compared for various rocks subtropics China. results showed that rates by GEM-CO2 vary from 1.64 27.40 mmol·m− 2·d− 1, while 2.63 ~ 13.46 1 water chemistry method. Similarly, calculated based on chemical rate individual specific mineral, ranging 0.03 19.03 1. calculation that, was 1.30 1.99 times summer than winter higher temperature precipitation. In extreme climates, high temperatures (≥ 30°C) heavy precipitation 25mm) have increased dioxide approximately 21.33% 66.23%, respectively. On interdecadal scale, 6.1% 1970 2020, rising 1.4°C, increasing 2.8%, partial pressure atmospheric (pco2) 28.4%. Further, we predict an increase will change 4.7 5.1% period 2020–2100 under four Representative Concentration Pathway (RCP) modes. findings this study offer novel scientific recommendations policy making neutrality.
