Thunderstorm-related delays dominate the overall U.S. airspace delay statistics and continue to increase (Figure 1), even though a number of new weather information systems and air traffic management (ATM) decision support tools have been deployed since 1999. The FAA is also concerned that anticipated increases in air traffic will result in much worse convective weather season delays by 2014 (H...

Proceeding from a stormy day of 22 September 2022, when 7 thunderstorm ground enhancements occurred (TGEs, 3 them very large), we perform an analysis the most important conditions, on which depend origination large particle fluxes in thunderous atmosphere. Among these conditions are near-surface electric field (NSEF), graupel fall, and lightning activity. We estimate intensity largest flux 1,25...

In Bangladesh, the lightning during a thunderstorm has recently been officially declared as natural disaster, resulting in numerous fatalities each year, especially country's northeast. This study aims to look into relationships between and climatic variables, spatial distribution of deaths, people's perceptions disaster's consequences adaptation measures, influencing factors that make people v...

[1] Inputs of heat and moisture through surface energy exchanges are important in the evolution of diurnally modulated thunderstorms. As part of the Maritime Continent Thunderstorm Experiment (MCTEX) conducted on the Tiwi Islands, northern Australia, we measured the surface energy exchanges above the dominant surface types (savanna, grassland, forest and shallow tidal strait). Measurements were...

BACKGROUND A study was undertaken to assess the importance of thunderstorms as a cause of epidemics of asthma exacerbations and to investigate the underlying mechanism. METHODS A case control study was performed in six towns in south eastern Australia. Epidemic case days (n = 48) and a random sample of control days (n = 191) were identified by reference to the difference between the observed ...

Weather extremes have harmful impacts on communities around Lake Victoria, where thousands of fishermen die every year because of intense night-time thunderstorms. Yet how these thunderstorms will evolve in a future warmer climate is still unknown. Here we show that Lake Victoria is projected to be a hotspot of future extreme precipitation intensification by using new satellite-based observatio...
