Light­ning strikes can be fore­cast now

Youth Street News - - Youth News -

Fi­nally, man can even pre­dict light­ning! In a re­mark­able in­ven­tion that is likely to save thou­sands of lives across the coun­try, Andhra Pradesh has come out with a sys­tem with which light­ning can be fore­cast well in ad­vance. And the in­ven­tion is pay­ing off.

The state was in fact able to save a lot many lives in the pre­mon­soon sea­son this year by pre­dict­ing in the fi­nal two weeks of May about pos­si­ble light­ning strikes in the vil­lages of Anant­pur and Chit­toor. This is quite a proac­tive mea­sure, con­sid­er­ing in the year 2015 alone, Andhra had had 75 ca­su­al­ties due to light­ning strikes.

The sys­tem has been de­vel­oped by the AP'S State Dis­as­ter mit­i­ga­tion So­ci­ety that works in con­junc­tion with the Depart­ment of Rev­enue and Re­lief. They have come out with this one-of-its-kind fore­warn­ing de­vice with the help of the ISRO and Earth Net­works, a US based tech­nol­ogy firm that has 1200 sen­sors in 40 coun­tries. this firm is ac­tive weather mon­i­tor­ing across the globe. The AP gov­ern­ment has pro­vided all the funds and sup­port for the state

or­gan­i­sa­tions' tie up with ISRO and Earth Net­works.

In May again, the AP ad­min­is­tra­tion was able to is­sue a ma­jor alert half an hour be­fore light­ning struck on 16 May in Kup­pam and Pala­maner blocks in the state's south­ern most cor­ner. No loss of life was re­ported be­cause of the fore­warn­ing. Vil­lagers in Gum­ma­gatta also es­caped un­hurt the next day de­spite a ma­jor light­ning strike as the au­thor­i­ties had alerted them in ad­vance.

The gov­ern­ment is now con­sid­er­ing de­vel­op­ing an app based on the sys­tem so that peo­ple in far off ar­eas too can be alerted on an ur­gent ba­sis ahead of a pos­si­ble calamity. Four­teen sen­sors have al­ready been set up in Kup­pam, Anan­ta­pur, Kurnool, Kadapa, Srikaku­lam and Visakhapatnam which are in the dan­ger prone zone for light­ning strikes.

The sen­sors are set up in high rise tow­ers in ar­eas that are in the dan­ger prone zone and these sen­sors de­tect the na­ture of the clouds' elec­tro­mag­netic ac­tiv­ity. the data is then fed to the con­trol com­mand sys­tem in the head of­fice where me­te­o­ro­log­i­cal depart­ment of­fi­cials an­a­lyse it and is­sue warn­ings.

It has been found that with the use of this sys­tem 90% ac­cu­rate pre­dic­tions can be made.
