May 2nd 2008, it’s another sadness day in human race’s history, where the cyclone Nargis has made landfall in the Ayeyarwady Division of Burma with the peak winds of 165 km/h (105 mph). According to the final report, there are more than 100,000 people died in this natural disaster and more than 1 million homeless, battling to stave off hunger and disease. This tragedy to be known as the fifth deadliest natural disaster in the human being’s history!
In order to prevent this catastrophe from being happened in the future and causing too much of scarify, a team researchers in Bard High School Early College, New York has discovered an amazing news! According to the study, most of the large spikes in lightning activity occurred near the eye wall 36 hours before its starting to violent. They called it, “eyewall replacement”, where it’s one of the many ways hurricanes intensify.
Natalia Solarzano, one of the team researchers said that hurricanes have very least lightning at their core. This is due to its winds within 60 miles from the eye are normally horizontal, which prevents the huge updrafts necessary to form ice crystals and supercooled water (These two methods are the basic things that can lead to lightning).
A very high-tech lightning detection network named “World Wide Lightning Location Network (WWLLN)” is being used to detect lightning within 30 miliseconds after a lightning strike. The team have confident that this WWLLN will be soon become an important tool for hurricane prediction as well!
