Michael Jackson Dies June 25 2009

Like many others on this forum and millions around the world, I was shocked about the news of Michael Jackson’s death. A musical and dancing genius and an incredible entertainer, it is a terrible loss for the music world and for those that followed his incredible career.

Hailstorms Forecast Service – 2 months FREE

admin — Wed, 24 Jun 2009 21:30:50 +0000

Forecasts of hailstorms will be posted on this website at the start of the season as the season unfolds from about August 2009. The first 2 months will be free. Depending on the risk and ability to pinpoint locations, the aim of the forecasts is to forecasts risk of severe weather occurring specifically targetted to hailstorms. The size of the possible hailstones will also be indicated. When the warning is high risk or sometimes even moderate, a more detailed forecast is provided attempting to include time of hail threat and regional locations that could be affected. The purpose of these hail forecasts is to provide anyone with as much lead up information to keep safe.

As always, weather is very unpredictable and these are provided as guidance despite the success rate should ONLY be used as a guide. Strange things have occurred even outside the zone. The main purpose of these forecasts are coverage of the eastern states – occasionally the Perth and Adelaide region and surrounds may also be covered.

A FREE warning service is available from the Early Warning Network (EWN) who provide enhanced warnings of approaching hailstorms, floods, bush fires, and other severe weather threats that may affect your region.

Abstract

A thunderstorm that developed over northeastern Spain on 16 June 2006 is analyzed. This severe thunderstorm produced hailstones as large as 40 mm and had a lifetime of 3 h and 30 min. Radar cross-sections show strong vertical development with cloud echo tops reaching an altitude of 13 km. The specific characteristics of the lightning activity of this storm were: (i) a large amount (81%) of negative cloud-to-ground (−CG) flashes with very low peak currents (< 10 kA in absolute value), (ii) a very large proportion of intra-cloud (IC) flashes with an IC/CG ratio reaching about 400, (iii) a large number of “short” IC flashes (with only 1-VHF source according to SAFIR detection), (iv) a large increase of the −CG flash rate and of the CG proportion near the end of the storm. The rate of −CG flashes with a low peak current were observed to evolve similarly to the rates of IC flashes. Most of them have been assumed to be IC flashes misclassified by the Spanish Lightning Detection Network (SLDN). They have been filtered as it is usually done for misclassified +CG flashes. After this filtering, CG flash rates remained very low (< 1 min^− 1) with +CG flashes sometimes dominant. All the particular lightning activity characteristics similar to those observed in the Severe Thunderstorm Electrification and Precipitation Study (STEPS) campaigns support the hypothesis that this thunderstorm could have had an inverted-polarity or complex charge structure. The maximum IC flash rate (67 min^− 1) peaked 24 min before the presence of reflectivity higher than 60 dBZ. The IC activity abruptly decreased during the period when reflectivity was dramatically increasing. The time of maximum reflectivity observed by radar was consistent with the times of reported hail at the ground….
