North China extreme precipitationUral blockingWestern Pacific subtropical highTrend turningThis study focuses on regional extreme precipitation (REP) in North China. We found a trend turning in summer (July to August) REP frequencies and intensities from a decrease trend in 1961–2002 to an increase...
An analysis of extreme precipitation events indicates that there has been a sizable increase in their frequency since the 1920s/1930s in the U.S. There has
The interactions between moisture convergence and topographic settings strengthen the extreme precipitation over NC. 展开 关键词: North China Extreme precipitation Moisture budget Moisture flux convergence Topography DOI: 10.1007/s00382-020-05139-z 年份: 2020 ...
Observed trends in extreme precipitation events in China during 1961–2001 and the associated changes in large-scale circulation [1] The observed trends in extreme precipitation events, and those in annual and seasonal mean precipitation in China during 1961–2001 are analyzed. Th... Y Wang - ...
In mid-June to July 2023, North China witnessed extreme heatwaves, marked by intense near-surface warming with an advanced seasonal cycle of local air temperature. An unconventional upper-tropospheric cold vortex in early June, deviating from conventional “heat dome” patterns, preceded the heatwave...
Elevated levels of particulate matter in the atmosphere are hazardous to human health and the environment. Severe particulate pollution days, with daily mean PM2.5 concentrations exceeding 150 μg m−3, occurred frequently in North China, especia
The interdecadal variations of summer precipitation in China and the drought trend in North China are analysed by using the observed data of summer precipitations (June～August) at 336 stations in China and SST in the Pacific from 1951 to 1994. The analysed results show that a climate jump of...
Research on the Relationship of ENSO and the Frequency of Extreme Precipitation Events in China Based on a daily precipitation observation dataset of 743 stations in China from 1951-2004,the螕distribution function is used to calculate the probability ... L Wei,P Zhai~2,JC1NC Center,... - 《...
Spatial–temporal variations in precipitation significantly influence infiltration, runoff, and other hydrological processes; and thus, in turn, they
Summer (June–August) heat waves in North China are found to be either primarily dry or moist, based on surface meteorological observations. This study characterizes synoptic circulation patterns (i.e., 500 hPa geopotential height) using the self-organizing map (SOM) method and investigates the ...
