Abstract. The tropopause plays a critical role in stratosphere–troposphere exchange and climate change. Its height is conventionally defined based on the World Meteorological Organization (WMO) threshold temperature gradient, yet this gradient intrinsically linked to vertical resolution. Data with higher resolution inevitably reveal finer structures. While situ radiosonde measurements are considered most reliable source for structure, high-resolution (5–10 m) soundings would be expected...
Abstract The planetary boundary layer is crucial for the turbulence mixing and exchange of heat flux, momentum, atmospheric pollutants between atmosphere Earth's surface. Nevertheless, estimated height (BLH) varies greatly by data sources algorithms. This paper seeks to characterize convective BLHs from 1‐s radiosonde measurements China Radiosonde Network (CRN) 2012–2020 period at 1400 Beijing time, using eight well‐known algorithms, wherein newly established Thorpe method theoretically...
Abstract Lower atmospheric gravity waves (GWs) can significantly impact in the middle and upper atmospheres are vital for turbulence generation. This paper puts spotlight on spatial–temporal variability of tropospheric GW total energy ( E T ) its potential sources above four regions interest (ROIs) gathered from high‐resolution radiosonde observations China Radiosonde Network during years 2016–2019. The seasonality ROIs shows different characteristics is dependent latitudes underlying...
Abstract Differentiating local‐scale precipitation (LP) and nonlocal‐scale (NLP) understanding their corresponding prestorm environment are of importance for accurate severe weather analysis forecasting. However, the difference in transient environments LP NLP is largely undetermined, thereby fundamentally limiting predictability convective storms. The present study focuses on precursor signals differences from those based explicit observational analyses using high‐resolution radiosonde...
Abstract The tropopause region is crucial for the stratosphere‐troposphere exchange (STE) and acts as an indicator of climate change. Double tropopauses (DTs) act to increase STE process but their driving mechanisms remain open question. present assessment offers first time linkage between tropospheric gravity waves (GWs) DT events by exploring a global data set multi‐year radiosonde measurements. In extratropics, occurrence frequency keeps remarkably consistent spatial‐temporal structure...
Wind shear has important implications for Kelvin–Helmholtz instability (KHI) and gravity waves (GWs) in the mesosphere–lower thermosphere (MLT) region where its momentum transport process is dominated by short-period (<1 h) GWs. However, sub-hourly variation wind still not well quantified. This study aims to improve current understanding of vertical analyzing multi-year meteor radar measurements at Mohe (MH, 53.5°N, 122.3°E), Beijing (BJ, 40.3°N, 116.2°E), Wuhan (WH, 30.5°N, 114.6°E),...
