Paracelsus (1493-1541) stands at a crossroads associated with the Renaissance andReformation. His cosmological-meteorological writings exemplify the turning pointthat progressively challenged the older worldview and opened fresh avenues. Hisnature philosophy is often, as can be seen here, the very ground on which hismedicine was built. This volume ...
Bouřky představují zásadní problém pro letištní provoz a jeho optimalizace je závislá na přísunu včasných a reálných informacích o počasí, které musí být dodány v nejlepším případě s dostatečným předstihem. Z provozních zkušeností letiště byly zjištěny problémy s včasným reportováním dat, některé výstrahy či zprávy z pozorování byly rozkolísané a č...
Drought, a prevalent and consequential natural disaster, poses widespread, indirect challenges across environmental and societal dimensions. Despite considerable focus on monitoring meteorological and hydrological drought and studying their characteristics, there is a gap in assessing its multifaceted impacts, especially on societal sectors. The di...
Precipitation change across the Central United States (USA) is of great interest to the research community. Studies using global climate simulations suggest that the “100th-Meridian”, which separates the “dry west” from the “moist east” will shift to the east as the climate responds to future emissions pathways. However, these simulations are run a...

This study investigates the prevalence and significance of forward-flank convergence boundaries (FFCBs) and left-flank convergence boundaries (LFCBs) in shaping the structure and intensity of supercells, using observational data from various field projects. Unlike previous research focusing on individual cases, this study examines a diverse range o...
Forecasting severe thunderstorm environments in the southeastern United States can be challenging due to mesoscale heterogeneities such as shortwave troughs, pre-existing airmass boundaries, cold fronts aloft, low-level jets, dry air intrusions, and mesoscale lows. To combat these challenges, ensemble sensitivity analysis (ESA) may be applied to a ...

Aerosols and rainfall have a significant role in atmospheric physical processes since they affect both the absorption and scattering of solar radiation and the composition of precipitation. Ultimately, this impacts the balance of radiation and water in the atmosphere. This study aims to clarify or understand the relationship between aerosols and ra...
Supercells have been researched extensively since they were first described over 50 years ago. They are prolific severe weather producers, responsible for the most severe hail, severe wind gusts, and tornadoes. These rotating thunderstorms require attention from forecasters to protect life and property from their threats, most effectively done with...
Left-moving (LM) supercells, though rarer than right-moving (RM) supercells, may produce significant severe weather. However, there are very few existing studies on LM supercells, particularly polarimetric radar analyses. The upgrade of the nationwide Weather Surveillance Radar-1988 Doppler (WSR-88D) network to polarimetric capability and subsequen...
