Thunderstorm anvils were studied during the Deep Convective Clouds and Chemistry experiment (DC3), using in situ measurements and observations of ice particles and NOx together with radar and Lightning Mapping Array measurements. A characteristic ice particle and NOx signature was found in the anvils from three storms, each containing high lightning flash rates in the storm core prior to anvil ...

The main objective of the current research was comparison of severe thunderstorm rainfalls with TRMM data when flash flooding events observed in the Sydney Metropolitan Area (SMA) located in NSW, Australia. Severe Thunderstorm Rainfall Events have been first extracted from the severe storm archive of the Australian BOM, by induction of specific criteria. The corresponded derived dataset includ...

BACKGROUND Thunderstorms and prior grass pollen counts were investigated as predictors of daily hospital admissions for asthma in England. This study was motivated by reports in the literature of spectacular asthma epidemics associated with thunderstorms, particularly in the grass pollen season. METHODS Asthma admissions for two age groups (0-14 years and 15 and over) were measured using the ...

Severe local storms, including tornadoes, damaging hail and wind gusts, frequently occur over the eastern and northeastern states of India during the pre-monsoon season (March-May). Forecasting thunderstorms is one of the most difficult tasks in weather prediction, due to their rather small spatial and temporal extension and the inherent non-linearity of their dynamics and physics. In this pape...

Abstract. We present a feasibility study for an object-based method to characterise thunderstorm properties in simulation data from convection-permitting weather models. An existing tracker, the Thunderstorm Identification, Tracking, Analysis and Nowcasting (TITAN) algorithm, was applied thunderstorms simulated by Advanced Research Weather Forecasting (AR-WRF) model at resolution domain centred...

[1] Precipitation measurements in complex terrain are difficult to obtain, particularly during convective thunderstorm precipitation or mixed rain and snow. In such cases, stream stage recorders distributed across many small, headwater streams can bridge the gap between point measurements of precipitation and larger-scale total basin discharge. We use case studies from two steep basins with sha...

This paper uses thunderstorm simulations, varying properties of thunderstorms consistent with the Southeast and Northeast U.S., in an attempt to explain the differences in Hg deposition between the regions. The model analyses are useful, explained thoroughly, and well-planned. However, the paper is essentially a model parameter space exploration for soluble tracer scavenging, and the conclusion...
