Thunderstorms have often been linked to epidemics of asthma, especially during the grass flowering season; however, the precise mechanisms explaining this phenomenon are unknown. Evidence of high respirable allergen loadings in the air associated with specific meteorologic events combined with an analysis of pollen physiology suggests that rupture of airborne pollen can occur. Strong downdrafts and dry, cold outflows distinguish thunderstorm rain from frontal rain. The weather system of a… 
Thunderstorm-triggered asthma: what we know so far
Understanding of the etiology of thunderstorm-triggered asthma and associated clinical indicators as well as possible biomarkers which may aid in predicting those at risk and thus those who should be targeted in prevention campaigns are extended.
Atmospheric modelling of grass pollen rupturing mechanisms for thunderstorm asthma prediction
If humidity induced rupturing cannot explain the 2016 Melbourne event, then new targeted laboratory studies of alternative pollen rupture mechanisms would be of considerable value to help constrain the parameterisation of the pollen rupturing process.
Managing Exacerbations in Thunderstorm Asthma: Current Insights
The identified risk factors of aeroallergen sensitization, specifically to RGP in Australians with a history of SAR, and individuals born in Australia of South-East Asian descent as a risk factor for TA has been key in selecting appropriate patients for preventative management.
Links between Pollen, Atopy and the Asthma Epidemic
This review outlines the mechanism of pollen fragmentation and possible pathophysiology of pollen fragment-induced asthma and examines synergistic effects and enhanced immune response from interaction in the atmosphere, or from co-deposition in the airways, of pollen allergens, endogenous pro-inflammatory agents, and the particulate and gaseous fraction of combustion products.

Allergens as trigger factors for allergic respiratory diseases and severe asthma during thunderstorms in pollen season
There are observations that thunderstorms occurring during pollen season can induce severe asthma attacks in pollinosis patients, and a dramatic event in Melbourne occurred on November 21, 2016, with 10 deaths and 9000 patients who needed medical treatments in Emergency Department of Melbourne Hospital for asthma attacks.

This review addresses the question of how pollen allergens originate in the environment, which has come from careful observations over 4 years of thunderstorm-associated epidemics of asthma in Melbourne and molecular cloning of rye-grass pollen allergic particles.
Release of allergens as respirable aerosols: A link between grass pollen and asthma.
First direct observations of the release of grass pollen allergens as respirable aerosols can emanate directly from the flower after a moisture-drying cycle are provided, which could explain asthmatic responses associated with grass pollination, particularly after moist weather conditions.
Thunderstorm-associated asthma or shortness of breath epidemic: a Canadian case report.
The elevated bioaerosol concentrations observed on the day of the thunderstorms may be attributed to the sudden onset of high winds during the thunderstorm, which triggered a sudden release of spores and pollens into the atmosphere, which was probably responsible for the epidemic.
Thunderstorm outflows preceding epidemics of asthma during spring and summer
Findings are consistent with the hypothesis that some epidemics of exacerbations of asthma are caused by high concentrations of allergenic particles produced by an outflow of colder air, associated with the downdraught from a thunderstorm, sweeping up pollen grains and particles and then concentrating them in a shallow band of air at ground level.
The role of fungal spores in thunderstorm asthma.
The results support a relationship between thunderstorms and asthma, and suggest that the mechanism may be through increases in spores that exacerbate asthma.
Effect of thunderstorms and airborne grass pollen on the incidence of acute asthma in England, 1990-94.
Very large sferic densities are associated with moderate rises in hospital admissions for acute asthma, however, typical thunderstorm days are not associated with spectacular asthma epidemics of the scale previously reported in the literature.
Mechanism of grass-pollen-induced asthma
Acute asthma epidemics, weather and pollen in England, 1987-1994.
Most epidemics are not associated with thunderstorms or unusual weather conditions, and most thunderstorms, even following high grass pollen levels, do not precede epidemics, so an early warning system based on the indicators examined here would detect few epidemics and generate an unacceptably high rate of false alarms.
Analysis of the relationships between environmental factors (aeroallergens, air pollution, and weather) and asthma emergency admissions to a hospital in Mexico City
A statistical analysis of the relationships between emergency admissions for asthma to a hospital in Mexico City and daily average airborne concentrations of pollen, fungal spores, air pollutants, and weather factors suggests aeroallergens may be statistically associated more strongly with asthma hospital admissions than air pollutants.
