Kitti Thupsri, technical specialist at the Phitsanulok rainmaking operation centre, said yesterday that since March the centre – covering seven lowernorthern provinces – had dispatched 137 rainmaking flights using 150 tonnes of chemicals which induced 32 days of rain and helped many farmers.
However, as the drought becomes more severe farmers – especially those growing rice, corn and sugarcane – are calling for more rainmaking operations. Kitti said the centre, that can send out two to three plane flights a day, yesterday dispatched aircraft to spray raininducing chemicals in Tak, Phitsanulok and Khamphaeng Phetch. He said if the drought remained severe, the rainmaking operations would need to continue until October.
