KSDMA member-scientist Sekhar Lukose Kuriakose said an expert team would soon visit the place where the phenomenon was experienced and could give a scientific explanation only after that.
However, he said prima facie evidence showed that the incidents were not related to 'heat wave' condition, which caused wide destruction in Pakistan recently, or acid rain phenomenon.
"We are yet to find out an exact reason for the phenomenon. But, considering the primary indications, it is assumed that the incidents were not connected with acid rain effect or heat wave. We can give a scientific explanation only after a detailed study," Kuriakose told PTI.
"As it is monsoon season, the chances of heat wave hitting the state is less. But place like Palakkad is more prone to such phenomenon in the state during summer season," the scientist added.
