The Asynchronous Evolution of Cold Waves Over China Revealed by 3D Spatiotemporal Tracking

Xin Zhang, Hongze Cai, Kaicun Wang, Yanyi He et autres

Abstract Cold waves pose substantial risks to ecosystems, infrastructure, and society. While most studies have examined their station‐level frequency or regional intensity, the joint behaviors in both time and space remain largely unexplored. Here, we apply a three‐dimensional connected‐component labeling algorithm to …

Rainfall-to-total precipitation proportion increased after bias correction over China from 1961 to 2022

Yun Li, Kaicun Wang

Abstract Gauge observations provide a traditional data source for investigating long-term precipitation changes, but wind-induced errors can cause undercatch, especially for snowfall. For decades, national standard gauges without wind shields were widely used in China. Since 2009, new weighing gauges with wind …

Day‐to‐Day Temperature Variability in Meteorological Observations and Reanalysis Data Over China

Xuejie Wang, Kaicun Wang, Yuna Mao, Guocan Wu

Abstract Temperature variability on the synoptic scale is most directly related to human perception, and requires more attention from scientists and researchers. This study quantifies the day‐to‐day temperature variability (DTD) as the absolute value of the difference between the air temperatures from …

Half-Century Monthly Mean PM2.5 over Global Land from Visibility Observations

Hongfei Hao, Kaicun Wang, Guocan Wu

Abstract Fine particulate matter (PM 2.5 ) significantly impacts the climate, environment, and human health. PM 2.5 data are obtained through direct ground-based measurements, indirect estimations, and modeling reanalysis. However, historical PM 2.5 data are limited by the short duration of ground-based …

Changing seasonality and advanced mean date of annual maximum daily precipitation in major river basins of China (1960–2018)

Yuna Mao, Jiayi Lu, Yan Zhang, Guocan Wu et autres

Abstract Extreme rainfall seasonality plays a critical role in vegetation growth, agricultural production, and water resource management. Under global warming, increasing attention has been paid to its seasonal shifts and nonstationarity characteristics. In our comprehensive research, we utilized daily precipitation data from …
