Climatology of Severe Hail in Finland : 1930 – 2006

A climatology of severe hail (2 cm in diameter or larger) in Finland was constructed by collecting newspaper, storm-spotter, and eyewitness reports. The climatology covered the warm season (1 May–14 September) during the 77-yr period of 1930–2006. Altogether, 240 severe-hail cases were found. The maximum reported severe-hail size was mainly 4 cm in diameter or less (65% of the cases), with the ...

Evaluation of Alberta Hail Growth Model Using Severe Hail Proximity Soundings from the United States

A one-dimensional, coupled hail and cloud model (HAILCAST) is tested to assess its ability to predict hail size. The model employs an ensemble approach when forecasting maximum hail size, uses a sounding as input, and can be run in seconds on an operational workstation. The model was originally developed in South Africa and then improved upon in Canada, using high quality hail verification data...

Evaluation of an Alberta Hail Growth Model Using Severe P9.5 Hail Proximity Soundings in the United States

Forecasters currently have very few tools at their disposal to aid them in predicting the maximum expected hail size. Moreover, the few tools that are available frequently forecast unrealistically large hail sizes in high CAPE environments. Perhaps the main reason for this is that the hail growth process is very complex and consequently, any ingredients-based forecasting methods that are typica...

An Analysis of Severe Hail Swaths in the Southern Plains of the United States

Severe hail is a common event in the Southern Plains of the United States. However, few studies have been conducted to quantitatively answer the question: how much hail occurs at any given location? Given the coverage of WSR-88D radars over the Southern Plains and recent technological advancements including hail detection algorithms, a compilation of severe hail swaths was completed for the per...
